Answer:

164 minutes

Step-by-step explanation:

Assuming that Jerome's seed is maintained, we say that for every 1 mile, he takes 13 minutes and 40 seconds which is equivalent to[tex]13\frac {2}{3}[/tex] since 1 minute has 60 seconds hence [tex]\frac {40}{60}[/tex]=[tex]\frac {2}{3}[/tex]

Now if

1 mile = [tex]13\frac {2}{3}[/tex]

12 miles=??

We cross multiply hence 12\times[tex]13\frac {2}{3}=164[/tex]

Therefore, Jerome needs 164 minutes, equivalent to 2 hours 44 minutes

Answer:

x = 26

Step-by-step explanation:

The parallel lines are Line l and Line m. The other line shown is the transversal.

When 2 parallel lines are cut by a trasversal it creates 4 euqual angles and another 4 equal angles of different measure.

The angle "5x + 7" is equal to the angle "8x - 71" since they are alternate exterior angles.

So, we can equate both expressions and use algebra to solve for "x". The process is shown below:

[tex]5x+7=8x-71\\8x-5x=71+7\\3x=78\\x=\frac{78}{3}\\x=26[/tex]

Hence,

the value of x is 26

The true statements are:

A. Tree A's heights are less spread out than tree B's heights and

B. Tree A has lower average height than tree B

Explanation:

Standard deviation in this case represents the spreading out of heights of the trees, Since tree A has lesser standard deviation given equal to 5 , it is less spread out than B given equal to 12, hence option A. is true.

The average of a quantity is given by mean so, the average height can be compared by the given mean values of the trees. Since, A has lesser mean value (= 25) than B(=60), tree A is said to have lower average height than tree B hence option B. is true.

Answer:

[tex]0.333 - 2.58 \sqrt{\frac{0.333(1-0.333)}{219}}=0.251[/tex]

[tex]0.333 + 2.58 \sqrt{\frac{0.333(1-0.333)}{219}}=0.416[/tex]

The 99% confidence interval would be given (0.251;0.416).

(25.0 ,41.6)

Step-by-step explanation:

1) Data given and notation  

n=219 represent the random sample taken    

X=73 represent the students that reported that they have at least $1000 of credit card debt.

[tex]\hat p=\frac{73}{219}=0.333[/tex] estimated proportion of students that reported that they have at least $1000 of credit card debt.

[tex]\alpha=0.01[/tex] represent the significance level

z would represent the statistic (variable of interest)    

p= population proportion of students that reported that they have at least $1000 of credit card debt.

2) Confidence interval

The confidence interval would be given by this formula

[tex]\hat p \pm z_{\alpha/2} \sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]

For the 99% confidence interval the value of [tex]\alpha=1-0.99=0.01[/tex] and [tex]\alpha/2=0.005[/tex], with that value we can find the quantile required for the interval in the normal standard distribution.

[tex]z_{\alpha/2}=2.58[/tex]

And replacing into the confidence interval formula we got:

[tex]0.333 - 2.58 \sqrt{\frac{0.333(1-0.333)}{219}}=0.251[/tex]

[tex]0.333 + 2.58 \sqrt{\frac{0.333(1-0.333)}{219}}=0.416[/tex]

And the 99% confidence interval would be given (0.251;0.416).

We are confident that about 25.1% to 41.6% of students have at least $1000 of credit card debt.

And for this case the most accurate option is:

(25.0 ,41.6)

The ounces of chocolate chips used by Mrs Jacob is 70 ounce

Solution:

Given that Jacob is making several batches of cookies and is using 84 total ounces of chips

Let "c" be the ounces of chocolate chips

Let "p" be the ounces of peanut butter chips

To find: ounces of chocolate chips used by Mrs Jacob

Given that There are 5 times as many ounces of chocolate chips as peanut butter chips

Thus we can frame a equation as:

ounces of chocolate chips = 5 x ounces of peanut butter chips

c = 5p -------- eqn 1

Jacob used 84 total ounces of chip. Therefore,

ounces of chocolate chips + ounces of peanut butter chips = 84

c + p = 84 ---- eqn 2

Substitute eqn 1 in eqn 2

5p + p = 84

6p = 84

Substitute p = 14 in eqn 1

c = 5(14) = 70

Thus the ounces of chocolate chips used by Mrs Jacob is 70 ounce

Answer: $9 per ticket

Step-by-step explanation: Unit price means the cost per unit. In this case, the cost per ticket.

Since we know that it costs $36 for 4 movie tickets, to find the cost for 1 movie ticket, we need to divide 4 into $36 or 4 into 36.

4 divides into 36 9 times. 9 x 4 is 36 and 36 - 36 is 0. So 4 divides into 36 9 times which means that each movie ticket costs $9.

So the unit price is $9 per ticket.

Distance between two points is 7

Explanation:

This is a question based on reflection of point w.r.t line. During reflection we can see the mirror image with t-shirt print inverted.But the  distance from mirror remains same.

Assume a point (x,y), and it reflect in x-axis, then x-axis serves as the mirror, and the new point is (x,-y), because the distance from the mirror remains same. If the reflection of the point is (x,y) in y-axis, then y-axis serves as the mirror, and the new point is (-x,y). And if you reflect (x,y) in y=x line, then new point will be (y,x).

So considering the above question, if new point is (5, -3.5), then the original point must be (5, 3.5)

Distance between two points [tex]P(X_1, Y_1)[/tex] and [tex]Q(X_2, Y_2)[/tex]is given by:

d(P, Q) = [tex]\sqrt{ (X_2-X_1)^{2} + (Y_2-Y_1)^{2}}[/tex]

[tex]Y_2-Y_2 = (3.5) - (-3.5) = 3.5+3.5 = 7\\ \\X_2-X_1 = 5 - 5 = 0[/tex]

[tex]So \sqrt {(Y_2-Y_1)^{2} + (X_2-X_1)^{2}} = \sqrt { 7^{2} + 0^{2}} = \sqrt { 14+0} = \sqrt {14} = 7[/tex]

So distance = 7

To calculate the CPI for year 2 in a simple economy involving shirts and pants, we first find the total cost of the basket in both years considering the price increase. Then, using the formula for CPI, we find that the CPI for year 2 is 122.45, indicating an increase in the average price level compared to the base year.

To calculate the Consumer Price Index (CPI) for year 2 in a simple economy with only shirts and pants in the basket of goods, we first need to understand the concept of CPI. The CPI represents the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. Here, we're given that the price of each item increases by $1 in year 2, with the new prices being $21 for pants and $26 for shirts.

First, calculate the total cost of the basket in year 2:
Cost of 3 shirts in year 2 = 3 shirts * $26 per shirt = $78
Cost of 2 pairs of pants in year 2 = 2 pants * $21 per pants = $42
Total cost of the basket in year 2 = $78 + $42 = $120

To determine the CPI for year 2, we also need to know the base year's total cost, which isn't directly provided here.

However, assuming the base year (year 1) prices were $1 less for each item, the prices would have been $20 for shirts and $19 for pants.

Cost of the basket in year 1:

Cost of 3 shirts = 3 shirts * $20 per shirt = $60

Cost of 2 pairs of pants = 2 pants * $19 per pants = $38

Total cost of the basket in year 1 = $60 + $38 = $98

Finally, to calculate the CPI for year 2, we use the formula:

CPI for year 2 = (Total cost of the basket in year 2 / Total cost of the basket in year 1) * 100
= ($120 / $98) * 100 = 122.45

Therefore, the CPI for year 2 is 122.45, indicating prices have increased on average when comparing year 2 to the base year (year 1). This helps in understanding the inflation rate and cost of living increases for consumers.

Answer:

1/256

Step-by-step explanation:

1/256

4^-4 as a fraction is 1/256. It cannot be further simplified because 1 and 256 have no common factors other than 1, making it the simplest form.

To express 4^-4 as a fraction and simplify it, we can apply the rule that states any non-zero number raised to a negative exponent is equivalent to 1 divided by that number raised to the positive exponent.

So, for 4^-4, we can write it as:

4^-4 = 1 / 4^4

Now, let's calculate 4^4:

4^4 = 4 * 4 * 4 * 4 = 256

So, we have:

4^-4 = 1 / 256

This is the fraction representation of 4^-4. To determine if it can be further simplified, we can check if the numerator and denominator have any common factors other than 1. In this case, 1 and 256 have no common factors other than 1.

Therefore, 1/256 is already in its simplest form. It represents the fraction equivalent of 4^-4, which is a small value. It means that 4 raised to the power of -4 is a very small positive number, specifically 1/256, indicating that the original number 4^-4 is less than 1 and quite close to zero in value.

The equation of line in point slope form is y - 4 = 7x - 56

Solution:

Given that m = 7 and point is (8, 4)

We have to find the equation of line in point slope form

It emphasizes the slope of the line and a point on the line

The point slope form is given as:

[tex]y - y_1 = m(x - x_1)[/tex]

Where "m" is the slope of line

Substitute m = 7 and (x, y) = (8, 4) in above point slope form

[tex]y - 4 = 7(x - 8)[/tex]

[tex]y - 4 = 7x - 56[/tex]

Thus equation of line in point slope form is found

We can write the equation in standard form

The standard form of an equation is Ax + By = C. In this kind of equation, x and y are variables and A, B, and C are integers.

[tex]y - 4 = 7x - 56\\\\7x - y -52 = 0[/tex]

Step-by-step explanation:

Point B(2, 8) reflect to x-axis

It means the x value won't change, the only thing that will change is the y value.

According to it, we can know that B' is (2, -8)

(2, -8) → (-8, 2+4) = (-8, 6) = B''

Final answer:

To obtain the coordinates of B'' after a reflection across the x-axis and a translation of (x,y)
ightarrow(y,x+4), point B(2,8) becomes B'(2,-8) after reflection and then B''(-8, 6) after translation.

Explanation:

The student is asking about the results of performing a geometric transformation on a point in the coordinate plane. Specifically, point B(2,8) is first reflected across the x-axis, and then is translated according to the rule (x,y)
ightarrow(y,x+4). To find the coordinates of B'', we follow these steps:

Reflect B across the x-axis: The x-coordinate remains the same, but the y-coordinate changes sign, resulting in B'(2,-8).

Apply the translation rule: We then take the coordinates of B' and apply the rule. The x-value of B' becomes the y-value of B'' and the y-value of B', decreased by 4, becomes the new x-value. Therefore, B'' = (-8, 2+4) = (-8, 6).

The final coordinates of B'' after the reflection and translation are (-8,6).

The number that satisfies the condition that, when added to five and then doubled, is one less than the number itself is -11. We found this number by setting up an equation and solving for the variable.

Let's define x to be the number we're trying to find. According to the question, if the sum of this number and five is doubled, the result is one less than the number.

The equation based on the given information is 2(x + 5) = x - 1. To solve for x, let's distribute the 2 to both terms in the parentheses: 2x + 10 = x - 1.

Next, we need to get all the x terms on one side and the constant terms on the other side. We can do this by subtracting x from both sides, giving us: x + 10 = -1. Then, subtract 10 from both sides to isolate x: x = -11. So, the number we're looking for is -11.
