Answer:

28%

Step-by-step explanation:

92-64=28

The percentage change in Alexandria's marks would be; 44%

A percentage is a minimum number or ratio that is measured by a fraction of 100. Percentage is the ratio of  the number for which you want to find  percentage to the total number with which you want to compare or out of and multiply this ratio with 100.

The percentage of change = (change in amount / original amount ) x 100

Alexandria's  marks in first attempt = 64

Alexandria's  marks in retake = 92

Then the Change in marks = 92-64 = 28

Thus Percentage of change on her tests

= ( change in marks / initial marks) ×100

=( 28/64)×100

= 43.75 %

≈ 44 %

Therefore, the percentage change in Alexandria's marks would be; 44%

Answer:

A and B

Step-by-step explanation:

A. In the number 4,235 the 4 represents 10 times as much as it represents in the number 2,435.

4,235 = 4 is 4,000

2,435 = 4 is 400

A. Is true

B. In the number 2,453 the 5 represents 10 times as much as it represents in the number 2,435.

2,453 = 5 is 50

2,435 = 5 is 5

True

C. In the number 3,245 the 3 represents 10 times as much as it represents in the number 2,435.

3,245 = 3 is 3,000

2,435 = 3 is 30

Not true

D. In the number 5,243 the 2 represents 110 as much as it represents in the number 2,435

Answer: t = 1 hour, 2 hours, 3 hours or 4 hours

Step-by-step explanation:

Reservation fee = $18

Additional fee per hour = $6 per hour

Number of hours to spend = t

The information in the question can be expressed as:

$18 + $6t < $48

$6t < $48 - $18

$6t < $30

t < $30/$6

t < 5

Answer:

Step-by-step explanation:

Given the line 2x-7y = -25

First let us get the slope of the line:

Rewrite the equation in the form y = mx+c

2x-7y = -25

-7y = -2x-25

y = -2x/-7-25/-7

y = 2/7 x +25/7

The slope of the line is 2/7

Ffor two lines to be perpendicular, the product of their slope must be -1

mM = -1

m(2/7)= -1

2m = -7

m = -7/2

Hence the lines perpendicular to the given line must be a line that has a slope of -7/2. Since we are not given option, we can say example of such line is y = -7/2 x + 15

Answer:

B. The graph is linear because it increases at a constant rate.

Answer:

The expectation is reasonable

Step-by-step explanation:

Since Jamal runs 1 mile in 5.05 minutes, and expected to run 5 km in 15.25 minutes, we need to find if this is true. So, we need to find if he can actually run 5 km in 15.25 minutes.

Now 1 mile = 1609 m and  5 km = 5000 m. So, 5 km = 5000 m × 1mile/1609 m

5 km = 5000/1609 mile

Also since Jamal runs 1 mile in 5.05 minutes, the time it takes to run 5 km = 5000/1609 mile is 5000/1609 mile × 5.05 minutes/1 mile = 25,250/1609 minutes = 15.69 minutes.

Since our calculation shows that Jamal runs a 5 kilometer race in 15.69 minutes, the expectation that he will break the record in 15.25 minutes is reasonable. He can only break the record if he runs faster since there is a difference of 15.69 - 15.25 minutes = 0.44 minutes = 0.44 × 60 = 26.4 seconds which is quite a short time. So the expectation is reasonable.

Answer: ( -3 1/2, -1 1/4 ) that's where it is on the coordinate plane...

Step-by-step explanation:

The point  ( -3 1/2, -1 1/4 ) on the coordinate plane is shown in the figure

The cartesian coordinate plane is an infinite 2 dimensional plane. Any 2 dimensional figure can be drawn on an infinite 2d plane. Each of the point of a cartesian plane is tracked by a location.

It is the perpendicular distance of that point from the horizontal axis and vertical axis, usually named x-axis and y-axis. The location is then written as: (a,b), where 'a' is that point's shortest distance from the y-axis and called x-coordinate of that point, and 'b' is that point's shortest distance from the x-axis, and called y-coordinate of that point.

Given;

Answer:

B. The length must decrease

Step-by-step explanation:

Given;

maximum volume of the tank, V = 24 ft³

maximum height of the tank, h = 4 ft

let the width of the tank = w

let the length of the tank = L

Volume of the tank is given by;

V = Lwh

L = V / (hw)

L = 24 / (4w)

L = 6/w

L is inversely proportional to w; an increase in w (width) will cause a decrease in L (length)

Therefore, If the designer increases the width of the fish tank, "The length must decrease"

Answer:

3(n+5)≥17

Step-by-step explanation:

3(n+5)≥17 is the expression for three times the sum of a number n and 5 is at least 17.

The relationship between two expressions or values that are not equal to each other is called inequality.

Given that three times, the sum of a number n and 5 is at least 17.

According to the question, the expression will be = 3(n+5)≥17

Hence, 3(n+5)≥17 is the expression for three times the sum of a number n and 5 is at least 17.

Answer:

The estimate of the average stopping distance of all model A tires with a 94% confidence interval is  

       [tex]132.94 <  \mu < 144.86[/tex]

Step-by-step explanation:

From the question we see that

   The sample size is  n  = 8

   The population standard deviation is  [tex]\sigma = 6.7[/tex]

Generally the sample mean is mathematically represented as

        [tex]\= x = \frac{\sum x_i }{n}[/tex]

=>     [tex]\= x = \frac{ 145 + 152 + \cdots + 133}{8}[/tex]

=>     [tex]\= x = 138.9[/tex]

From the question we are told the confidence level is  95% , hence the level of significance is    

      [tex]\alpha = (100 - 94 ) \%[/tex]

=>   [tex]\alpha = 0.04[/tex]

Generally the degree of freedom is mathematically represented as

      [tex]df = n - 1[/tex]

=>   [tex]df = 8 - 1[/tex]

=>   [tex]df = 7[/tex]

Because the n < 30  we will making use of the t table

Generally from the t distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] at a  degree of freedom of [tex]df = 7[/tex]  is  

   [tex]t_{\frac{\alpha }{2}, 7 } = 2.517 [/tex]

Generally the margin of error is mathematically represented as  

      [tex]E = t_{\frac{\alpha }{2} , df} *  \frac{\sigma }{\sqrt{n} }[/tex]

=>    [tex]E = 2.517 *  \frac{6.7 }{\sqrt{8} }[/tex]

=>     [tex]E =5.96 [/tex]

Generally 94% confidence interval is mathematically represented as  

          [tex]\= x -E <  \mu <  \=x  +E[/tex]

=>        [tex]138.9  -5.96 <  \mu < 138.9  + 5.96[/tex]

=>        [tex]132.94 <  \mu < 144.86[/tex]

Answer:

54

Step-by-step explanation:

Given f(x) = 6(1 - x), what is the value of f(-8)?

F(-8)=6(1--8)        -- plug -8 into f(x) and x spots.

F(-)8=6(9)      ---then solve

F(-8)=54     --- so the function to f(-8) is 54
