Answer:

Due to the higher z-score, she did better in the free throw category.

Step-by-step explanation:

Z-score:

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question:

She did better in the category that she had the higher z-score:

Free-throws:

Her free throw percentage was 79%, which means that [tex]X = 79[/tex]

The team averaged 87% from the free throw line with a standard deviation of 12, which means that [tex]\mu = 87, \sigma = 12[/tex]. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{79 - 87}{12}[/tex]

[tex]Z = -0.67[/tex]

Steals:

She had 4 steals, which means that [tex]X = 4[/tex]

Averaged 7 steals with a standard deviation of 3, which means that [tex]\mu = 7, \sigma = 3[/tex]. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{4 - 7}{3}[/tex]

[tex]Z = -1[/tex]

Due to the higher z-score, she did better in the free throw category.

Answer:

  5 miles

Step-by-step explanation:

It may get a bit messy, but we can solve for the desired value directly. Let d = the distance walked (in miles). Then 20-d is the distance traveled in the car. The relevant relation is ...

  time = distance / speed

The total travel time is 9:00 -6:50 = 2:10 = 2 1/6 hours = 13/6 hours. Here is the equation for total travel time.

  total time = time spent walking + time spent riding

  13/6 = (d/3) + (20-d)/30

Multiplying by 30 gives ...

  65 = 10d + 20 -d

  45 = 9d . . . . . . . . . . subtract 20

  5 = d . . . . . . . . . . . . divide by 9

The girl walked 5 miles.

_____

Check

Her walking time was (5 mi)/(3 mph) = 5/3 h = 1:40.

Her riding time was (15 mi)/(30 mph) = 1/2 h = 0:30.

Her total travel time was 1:40 +0:30 = 1:70 = 2:10, as required.

Answer:

f5= 5

Step-by-step explanation:

The value of F₅ in the given Fibonacci sequence is 5, i.e. option A is the correct answer.

Fibonacci sequence is a sequence in which each number is the sum of the two preceding ones.

i.e.

[tex]F_n = F_{n-1} + F_{n-2}[/tex]

We have,

Fibonacci sequence {0, 1, 1, 2, 3, 5, 8, ...}

i.e.

F₁ = 0, F₁ = 1, F₂ = 1, F₃ = 2, F₄ = 3, F₅ = 5, F₆ = 8

Now,

We have to find the value of F₅,

Here, for n = 5,

i.e.

[tex]F_5 = F_{5-1} + F_{5-2}[/tex]

i.e.

F₅ = F₄ + F₃

So,

F₅ = 3 + 2

So,

We get,

F₅ = 5

So, the value of  F₅ for the given sequence is  F₅.

Hence, we can say that the value of F₅ in the given Fibonacci sequence is 5, i.e. option A is the correct answer.

Answer:

Step-by-step explanation:

The predicted value of $16,348 for the car in 2014.

The depreciation rate is the percentage rate at which an asset is depreciated over its projected useful life.

Given,

The car was purchased for $22,800 in 2010.

The value of the car was $14,100 in 2012.

The time elapsed between 2010 and 2012 is 2 years, so we can calculate the annual depreciation rate as follows:

depreciation rate = (purchase price - value after 2 years) / (purchase price x 2 years)

= (22,800 - 14,100) / (22,800 * 2)

= 0.0798 or 7.98%

This means that the car depreciates by approximately 7.98% of its value per year. To predict the value of the car in 2014, we can use this rate to calculate the value after 4 years (since 2010):

value after 4 years = purchase price x (1 - depreciation rate)⁴

= 22,800 x (1 - 0.0798)⁴

≈ 16,347.97

Rounding this to the nearest dollar gives us a predicted value of $16,348 for the car in 2014.

Answer:

  11.  (-4, -1)

  12.  (2, 7)

Step-by-step explanation:

The midpoint is the average of the end point coordinates. For segment AB, the midpoint M is ...

  M = (A+B)/2

If you have A and M, you can find the other end point B from ...

  2M = A+B . . . . multiply the above equation by 2

  B = 2M -A . . . . subtract A from both sides

__

11. The midpoint (M) is ...

  M = ((-1, 2) +(-7, -4))/2 = (-1-7, 2-4)/2 = (-8, -2)/2

  M = (-4, -1)

__

12. The missing end point is ...

  Z = 2Y -X

  Z = 2(-4, 8) -(-10, 9) = (2(-4)+10, 2(8) -9)

  Z = (2, 7)

Step-by-step explanation:

Answer:

A). (1, 7)

Step-by-step explanation:

-3x – 2y = -17

9x + 2y = 23

____________+

6x = 6

x = 6/6

x = 1

9x + 2y = 23

9(1) + 2y = 23

9 + 2y = 23

2y = 23 - 9

2y = 14

y = 14/2

y = 7

Answer:

P = 7

Step-by-step explanation:

We have 21 total cards and out of those 21 cards, 14 of those are birthday cards. So that means that the amount of cards that are not birthday cards is the number of cards subtracted by the number of birthday cards, also shown as 21 - 14. So 21 - 14 = P, so now we solve what 21 - 14 is which is 7, so that means P = 7.

Answer:

y = -5x -10

Step-by-step explanation:

This is the slope-intercept form:

[tex]y-y_{1} = m(x -x_{1})[/tex]

First, we look for the slope. The slope is found by using the equation:

[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1}}[/tex]

[tex]m = \frac{5 - (-25)}{-3 - 3} = \frac{30}{-6} = -5[/tex]

m = -5.

Now, given the two points, our y₁ is -25, and our x₁ is 3. Therefore, we substitute these values into the equation, and get:

y - (-25) = -5(x - 3)

y + 25 = -5(x - 3)

y + 25 = -5x + 15

y = -5x + 15 -25

y = -5x -10

Answer:

the answer to the problem is y= -5x - 10

Answer:

Percentage error of your estimate = 13%    

Step-by-step explanation:

Given

Approximate value = 85

Exact value = 75

To determine

Percentage error can be determined using the formula

Percentage Error =  |Approximate Value − Exact Value| / |Exact Value| × 100%

                             = |85 − 75| / |75| × 100%

                             = 10 / 75 × 100%

                             = 0.1333 × 100%

                             = 13%

Therefore, percentage error of your estimate = 13%

Answer:

$65.52

Step-by-step explanation:

y = mx + b

y = amount spent on fuel = ?

m = price per gallon = $3.90

x = gallons  = 16.8

b is not needed for this problem

y = (3.90)(16.8)

y = $65.52

The amount of money that Sam spends on fuel will be $65.52.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

To fill up his fuel tank, Sam puts in 16.8 gallons of gas at $3.90 per gallon.

The amount of money that Sam spends on fuel will be given by the multiplication of the numbers 16.8 and 3.9.

⇒ $3.90 x 16.8

⇒ $65.52

The amount of money that Sam spends on fuel will be $65.52.
