Answer:

C. 33

Step-by-step explanation:

The pattern increases by 4; 17+4=21, 21+4=25, 25+4=29, 29+4=33

Answer:

(a)Mean=14

(b)Median=14.5

Step-by-step explanation:

Given the data set:

5,5, 9, 10, 13, 16, 18, 20, 22, 22​

(a)Mean

[tex]\bar{x}=\dfrac{5+5+9+10+13+16+18+20+22+22}{10} \\=\dfrac{140}{10} \\Mean=14[/tex]

(b)5,5, 9, 10, 13, 16, 18, 20, 22, 22​

Since we have two terms in the middle, we take the average to obtain the median.

Median

[tex]=\frac{13+16}{2}\\=\frac{29}{2}\\Median=14.5[/tex]

Answer:

1/7

Step-by-step explanation:

The following information is missing:

Captain Nadia has a ship, the H.M.S Crimson Lynx. The ship is two furlongs from the dread pirate Tiffany and her merciless band of thieves.

If her ship hasn't already been hit, Captain Nadia has probability 1/2 of hitting the pirate ship. If her ship has been hit, Captain Nadia will always miss.

If her ship hasn't already been hit, dread pirate Tiffany has probability 2/7 of hitting the Captain's ship. If her ship has been hit, dread pirate Tiffany will always miss.

Let's call:

A: captain hits, P(A) = 1/2

A': captain miss, P(A') = 1 - P(A) = 1/2

B: pirate hits

We want to calculate P(A'∩B). This can be computed as follows:

P(A'∩B) = P(A')*P(B|A')

where P(B|A') means pirate hits given that captain miss. We know that P(B|A') = 2/7.  Replacing data into the equation:

P(A'∩B) = (1/2)*(2/7) =1/7

Answer:

B

Step-by-step explanation:

The transformation is proved through comparing the size of the bigger triangle to the smaller triangle in the individual sides. So the size of A F/ AB should be equal to AG / AC due to transformations making A F and AG the same times longer as AC and AB. By performing those calculations, you get 3.

Answer:

2.5 miles

Step-by-step explanation:

Jen ran for 10 minutes. This is 1/6 of an hour.

1/6*6=1

He covered 1 mile in that 10 minutes.

Jen then walked for 30 minutes. This is 1/2 of an hour.

1/2*3=1.5

He covered 1.5 miles in that 30 minutes.

1+1.5=2.5

The total distance covered by Jen is 2.5 miles.

Answer:

2.5

Step-by-step explanation:

Answer: 562.5

Step-by-step explanation:

Ok...Im PRETTY sure this is right, because you multiply 5 (5 years till 2025) times 7.5 (the rate of decrease in price) and subtract that from 500, so that would be 600-37.5, which gives you 562.5

Okay, so the formula for these types of problems is [tex]yab^x[/tex] I believe, or something like that.

So the price is 600 for y, 1-0.0075 is the b because it is decreasing in value each year, and it is 5 years from now, so 5 for the x.

Plug those in, and you will get about 577.83.

I hope this helps.

Answer:

The critical z value used to test a null hypothesis is ±1.75.

Step-by-step explanation:

We are given that the data has a normal distribution and the number of observations is greater than fifty.

Also, the hypothesis given to us is;

Null Hypothesis, [tex]H_0[/tex] : [tex]\mu[/tex] = 3.24

Alternate Hypothesis, [tex]H_1[/tex] : [tex]\mu\neq[/tex] 3.24

This means that our test is two-tailed because in the alternate hypothesis we are concerned with mean value is less than or greater than 3.24.

Also, level of significance (α) = 0.08

Now, for two-tailed test level of significance becomes =  [tex]\frac{\alpha}{2} =\frac{0.08}{2}[/tex] = 0.04

So, in the z-table the critical value of x at 4% significance level is given as 1.75.

Since, this is two-tailed test so the critical z value used to test a null hypothesis would be ±1.75.

At the 4% significance level, the z-value is 1.75. Therefore, for the two tailed test the z value becomes [tex]\pm[/tex] 1.75. and this can be determined by using the given data.

Given :

According to the hypothesis test:

Null Hypothesis  --  [tex]\rm H_0:\mu=3.24[/tex]

Alternate Hypothesis  --  [tex]\rm H_1 : \mu\neq 3.24[/tex]

According to the given data, the significance level is given by ​α = 0.08. So, the significance level for the two tailed test is given by:

[tex]\rm \dfrac{\alpha }{2}=\dfrac{0.08}{2}=0.04[/tex]

So, for the 4% significance level, the z-value is 1.75. Therefore, for the two tailed test the z value becomes [tex]\pm[/tex] 1.75.

So, the correct option is a).

Answer:

The amount financed under this mortgage is $185,600

Step-by-step explanation:

Alice took out an 80/20 mortgage on a $232,000 home.

80/20 mortgage means pay 20% down payment and 80% finance amount of home value.

Home value = $232,000

Now, we need to find finance amount from this hone value of $232,000

Let's calculate the 80% of $232,000 as finance amount;

Finance amount = 80% of 232000

 Finance amount  = 0.80 x 232000

Finance amount = 185,600

Step-by-step explanation:

To find the sum, you most find the answers for both powers of tens. 10^2 is 100, so 4.9*100=490. 10^3 is 1000, so 6.8^1000= 6800. Add them together and you get 7290, which if divided by 1000, you get 7.29. Since 10^3 is 1000, the correct answer isE.

The surface area of the cylinder is [tex]\( 72\pi \)[/tex] or approximately [tex]\( 227.836 \)[/tex] square units when using [tex]\( \pi \approx 3.143 \)[/tex].

The surface area of a cylinder can be calculated using the formula:

[tex]\[ \text{Surface Area} = 2\pi r^2 + 2\pi r h \][/tex]

where [tex]\( r \)[/tex] is the radius of the base and [tex]\( h \)[/tex] is the height of the cylinder.

Given the base radius [tex]\( r = 4 \)[/tex] and the height [tex]\( h = 5 \)[/tex], we can substitute these values into the formula:

[tex]\[ \text{Surface Area} = 2\pi (4)^2 + 2\pi (4)(5) \][/tex]

[tex]\[ \text{Surface Area} = 2\pi (16) + 2\pi (20) \][/tex]

[tex]\[ \text{Surface Area} = 32\pi + 40\pi \][/tex]

[tex]\[ \text{Surface Area} = 72\pi \][/tex]

Now, if we use the approximation[tex]\( \pi \approx 3.143 \)[/tex], the surface area becomes:

[tex]\[ \text{Surface Area} \approx 72 \times 3.143 \][/tex]

[tex]\[ \text{Surface Area} \approx 227.836 \][/tex]

count all the dots that are greater than 10. you'll get 6 dots. the question is asking for the dots 10 and fewer there is 40 dots in total so you subtract

40-6= 34

the answer is 34/40

The probability for the dots 10 and fewer shots to get a successful shot is 34/40

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

The probability that Gerald makes a three-point shot in basketball is 20%.

He simulated 40 trials of three-point shots where each shot had a 0.2 probability of being successful, and in each trial, he counted how many shots it took to get the first successful shot.

all the dots that are greater than 10 = 6 dots.

we need to find for the dots 10 and fewer there are 40 dots in total

So,

40-6= 34

Thus, the answer is 34/40

Which of the following is true if the data point 11.1 is corrected to 11.7?

A.The mean increases.

B.The median increases.

C.The data set has two modes.

D.The range increases.

A.The mean increases.

C.The data set has two modes.

These are the correct answers.

A and C will be correct answers.

The average of a group of variables is referred to as the mean in mathematics and statistics. There are several methods for calculating the mean, including basic arithmetic means (adding the numbers together and dividing the result by the number of observations), geometric means, and harmonic means.

Given that the Data point is corrected from 11.1 to 11.7. As we already know if we increase the value of the data point the mean will rise when a data point is added that is above the mean or subtracted that is below the mean. The mean will drop if one or more data points are removed that are above the mean or added that are below the mean.

Therefore, If data point 1.1 is corrected to 11.7 then the mean will increase and the data set has two modes.

Answer:

0.6968 L

Step-by-step explanation:

We can calculate the resulting volume thanks to Boyle's Law, which tells us The volume is inversely proportional to the pressure:

• If the pressure increases, the volume decreases.

• If the pressure decreases, the volume increases.

Thus:

P1V1 = P2V2

We know that P1 = 12 atm, V1 = 0.0871 L and P2 = 1.5 atm, that is, the value that we do not know about V2, therefore we solve for V2:

V2 = P1V1 / P2

Replacing:

V2 = 12 * 0.0871 /1.5

V2 = 0.6968 L

Which makes sense, since decreasing the pressure increases the volume.

Step-by-step explanation:

The product of (3 – 2i) and (3 + 2i) simplifies to 13 after expanding and simplifying the expression, canceling out the imaginary terms.

To find the product of (3 – 2i) and (3 + 2i), we'll use the distributive property:

(3 - 2i)(3 + 2i) = 3(3) + 3(2i) - 2i(3) - 2i(2i)

                = 9 + 6i - 6i - 4i²

Since i² = -1, substitute -1 for i²:

= 9 + 6i - 6i - 4(-1)

= 9 + 6i - 6i + 4

The terms with imaginary parts cancel out:

= 9 + 4

= 13

Thus, the product of (3 – 2i) and (3 + 2i) equals 13.
