Answer:
heat the air
Step-by-step explanation:
Lightning is just a high-intensity amount of electricity. Picture zapping something with electricity: it doesn't get cold, it gets hot.
That's because when a current is passed through something, it has more energy, so the molecules start to vibrate faster and move around much faster than they were before, which causes friction and a buildup of heat.

To shift a function to the right by h units, replace x with (x -h). Here, the value of h is -π/2, so the function is shifted the opposite of right.
The function is shifted to the left by π/2 units.
A parks and recreational board in Birch County is interested in estimating the proportion of its residents in favor of having more public parks in that county. A random sample of Birch County residents was selected. All the selected residents were asked, "Are you in favor of having more public parks in your county?" A 98% confidence interval for the proportion of residents in favor of having more public parks in that county was calculated to be 0.54 ± 0.03. Which of the following statements is correct?
a. At the 98% confidence level, the majority of area residents is in favor of having more public parks in that county.
b. At the 98% confidence level, the estimate of 0.54 is within 0.03 of the true proportion of county residents in favor of having more public parks in that county.
c. In repeated sampling, 98% of sample proportions will fall in the interval (0.51, 0.57).
d. In repeated sampling, the true proportion of county residents in favor of having more public parks in that county will fall in the interval (0.51, 0.57).
e. In repeated sampling, 98% of the time the true proportion of county residents in favor of having more public parks in that county will be equal to 0.54.
Answer:
B.
Step-by-step explanation:
Trust me.
I just did it.
The correct statement is:
In repeated sampling, the true proportion of county residents in favor of having more public parks in that county will fall in the interval (0.51, 0.57).
Option D is the correct answer.
What is a confidence interval?A confidence interval is a range of values that is likely to contain the true value of an unknown parameter, such as a population means or proportion, based on a sample of data from that population.
It is a statistical measure of the degree of uncertainty or precision associated with a statistical estimate.
We have,
The 98% confidence interval for the proportion of residents in favor of having more public parks in the county is 0.54 ± 0.03.
This means that we are 98% confident that the true proportion of residents in favor of having more public parks in the county falls within the interval from 0.51 to 0.57.
Now,
The correct statement is:
In repeated sampling, the true proportion of county residents in favor of having more public parks in that county will fall in the interval (0.51, 0.57).
Option a is incorrect because we cannot determine whether the majority of residents are in favor of having more public parks based solely on the confidence interval.
Option b is incorrect because we cannot determine whether the estimate of 0.54 is within 0.03 of the true proportion of county residents in favor of having more public parks based solely on the confidence interval.
Option c is incorrect because it is a statement about the probability of the sample proportion falling within the interval in repeated sampling, which is not the same as the true proportion falling within the interval.
Option e is incorrect because it is a statement about the probability of the true proportion being equal to 0.54 in repeated sampling, which is not necessarily true based solely on the confidence interval.
Thus,
The correct statement is:
In repeated sampling, the true proportion of county residents in favor of having more public parks in that county will fall in the interval (0.51, 0.57).

Jack and Jill both ordered pizzas from Wayne’s pizza for their parties. Jack paid $58.50 for 3 pepperoni pizzas and 2 plain pizzas. Jill paid $67 for two pepperoni pizzas and 4 plain pizzas. How much does Wayne’s pizza charge for a plain pizza and for a pepperoni pizza ?
Answer:
A plain pizza is $10.50. A pepperoni pizza is $12.50.
Step-by-step explanation:
Solve a system of equations. Call x the price of plain pizzas and y the price of pepperoni pizzas. From the question we are told that for Jack:
[tex]58.50=2x+3y[/tex]
And for Jill:
[tex]67=4x+2y[/tex]
There are several ways to solve this. I'll used elimination. Multiply the first equation by 2:
[tex]117=4x+6y[/tex]
Now subtract the second equation from the first - this will get rid of the x, leaving only y, which can be solved for:
[tex](117-67)=(4x-4x)+(6y-2y)\\50=4y\\y=12.5[/tex]
Now sub the value for y into either of the original equations and solve for x. I'll use the first:
[tex]58.5=2x+3(12.5)\\58.5=2x+37.5\\21=2x\\x=10.5[/tex]
Answer:
One plain pizza would be $10.50 and one pepperoni pizza would be $12.50.

The value of Q is given by the relation Q = 17m. If m is an integer greater than 15 and less than 23, then which of the following is the value of Q?
complete question:
The value of Q is given by the relation Q = 17m. If m is an integer greater than 15 and less than 23, then which of the following is the value of Q?
A. 255
B. 290
C. 306
D. 391
Answer:
C. 306
Step-by-step explanation:
The equation is Q = 17m. m is an integer and it is greater than 15 and less than 23 . This means m can only be 16, 17, 18, 19, 20, 21 and 22.
Insert any of the value of Q from the options in the equation Q = 17m and solve the equation. The answer of m must be between 16 to 22.
let us try
option A
Q = 17m
255/17 = m
m = 15 (not A since it not greater than 15)
option B
Q = 17m
290/17 = m
m = 17.0588235294
(not an integer)
option C
Q = 17m
306/17 = m
m = 18
(correct . it is an integer and greater than 15 and less than 22)
option D
Q = 17m
391/17 = m
m = 23
(not less than 23)

Step-by-step explanation:
In ΔHIJ, the measure of ∠J=90°, the measure of ∠I=29°, and JH = 88 feet. Find the length of IJ to the nearest tenth of a foot.
We have been given that in ΔHIJ, the measure of ∠J=90°, the measure of ∠I=29°, and JH = 88 feet. We are asked to find the length of IJ to the nearest tenth of a foot.
First of all, we will draw a right triangle using our given information as shown in the attachment.
We can see that in triangle HIJ, the side IJ is adjacent side to angle I and JH is opposite side to angle I.
We know that tangent relates opposite side of right triangle to adjacent side.
[tex]\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}[/tex]
[tex]\text{tan}(29^{\circ})=\frac{88}{IJ}[/tex]
[tex]IJ=\frac{88}{\text{tan}(29^{\circ})}[/tex]
[tex]IJ=\frac{88}{0.554309051453}[/tex]
[tex]IJ=158.7562024638191237[/tex]
Upon rounding to nearest tenth, we will get:
[tex]IJ\approx 158.8[/tex]
Therefore, the length of the side IJ is approximately 258.8 units.

Answer:
Using the formula a² + b² = c², we can plug in those two numbers, which I assume are the legs, to get our answer.
- Once we plug it in, we have to isolate the variable.
THEN
- We must square root (√) the final answer. Like so:
6.4² + 8.9² = c²
DO: The variable is already isolated, so we must do this a little differently. We'll square each number like it shows, and then add the two numbers together.
6.4² = 40.96
8.9² = 79.21
NOW: We can add them together.
40.96 + 79.21 = 120.17
LOOK: 120.17 = c²
We must now get rid of the 2, by square rooting both sides!
10.9622078068 = c

Find the sum of the first 200 terms of the arithmetic sequence:
4,7,10,13,...
Answer:

Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = 4 and d = 7 - 4 = 3, thus
[tex]S_{200}[/tex] = [tex]\frac{200}{2}[/tex] [ (2 × 4) + (199 × 3) ]

A device tests whether each light on a string of LED lights is functioning properly. A company estimates that 2.3% of LED lights that they produce are defective. The device is 96% accurate for lights that are functioning properly and 94% accurate for lights that are defective. You use the device to test a randomly selected light. What is the probability that the test result is correct? Round your answer to the nearest tenth.
Answer:
96% probability that the test result is correct
Step-by-step explanation:
We have these following probabilities:
2.3% probability that a randomly selected light is defective.
If the light is defective, 94% probability that the test result is correct.
100-2.3 = 97.7% probability that a randomly selected light is not defective.
If the light is not defective, 96% probability that the test result is correct.
What is the probability that the test result is correct?
94% of 2.3% and 96% of 97.7%. So
p = 0.94*0.023 + 0.96*0.977 = 0.96
96% probability that the test result is correct

What is the second step to solve for x?
We have been given an equation [tex]gv=-3x +5[/tex]. We are asked to solve our given equation for x.
First of all, we will separate expression with x on one side of equation. We can do it by subtracting 5 from both sides of equation.
[tex]gv-5=-3x +5-5[/tex]
[tex]gv-5=-3x[/tex]
Now we will switch the sides as:

find the semicircular. Either enter an exact answer in terms of n pi or use 3.14 for n and enter your answer as a decimal.
Answer:
Area = 25.12 square units.
Perimeter = 20.56 units
Step-by-step explanation:
If you are looking for area, here goes:
Area of circle = π * r^2
Area of semi-circle = S = (1/2) *π * r^2
S = (1/2)*π*(4^2) = (1/2)π*16 = 8π square units = 25.12 square units
Or if you are looking for the perimeter:
Circumference C = 2*π*r
Half-circumference = (1/2)C = (1/2)*2*π*r = π*r = π*4
Perimeter of semi-circle = 4 + 4 + 4π = 8 + 4π

D. 60 hL = 60000L
Answer:
C. 60 dL = 6000 mL
60 x 100 = 6000
Step-by-step explanation:
Formula: multiply the value by 100
Final answer:
The statement that is true is D, which correctly states that 60 hectoliters are equal to 60000 liters, as 1 hectoliter equals 1000 liters.
Explanation:
The student has asked which statement is true regarding the comparison of different units of volume measurement. Only one of the statements given represents an accurate conversion:
Answer D
60 hectoliters (hL) equals 60000 liters (L). This is true because 1 hectoliter is equivalent to 1000 liters. Hence, if we have 60 hectoliters, we multiply 60 by 1000 to find the conversion in liters:
60 hL * 1000 L/hL = 60000 L
Therefore, statement D is correct.

Eliana owns the Blossom garden shop. To keep her plants healthy, she always adds 3 cups of fertilizer for every 8 cups of soil. She filled a large pot with 24 cups of soil for a ficus plant. How many cups of fertilizer should Eliana add to the pot?
Answer: Eliana should add 9 cups of fertilizer to the pot.
Step-by-step explanation:
Given , Eliana always adds 3 cups of fertilizer for every 8 cups of soil. .
As the quantity of fertilizer is proportional to the quantity of soil.
That means,
[tex]\dfrac{\text{Number of cups of fertilizer for 24 cups of soil}}{\text{24}}=\dfrac{\text{Number of cups of fertilizer for 8 cups of soil}}{8}\\\\\Rightarrow \dfrac{\text{Number of cups of fertilizer for 24 cups of soil}}{24}=\dfrac{3}{8}[/tex]
Multiply 24 on both sides , we get
[tex]\Rightarrow\ \text{Number of cups of fertilizer for 24 cups of soil}=\dfrac{3}{8}\times24=3\times3=9[/tex]
Hence, Eliana should add 9 cups of fertilizer to the pot.
Eliana should add 9 cups of fertilizer to the pot.
Explanation:To determine how many cups of fertilizer Eliana should add to the pot, we can use the given ratio of 3 cups of fertilizer for every 8 cups of soil. Since Eliana filled the pot with 24 cups of soil, we can set up the following proportion:
3 cups of fertilizer / 8 cups of soil = x cups of fertilizer / 24 cups of soil
By cross-multiplying and solving for x, we find that Eliana should add 9 cups of fertilizer to the pot.
