Answer:

Sabrina bought 3 pounds of bananas.

Step-by-step explanation:

Given equations are:

a + b = 8       Eqn 1

0.95a + 1.10b = 8.05    Eqn 2

As we have to find the number of pounds of bananas bought, we will eliminate the variable a from the equation.

Multiplying Eqn 1 by 0.95

0.95(a+b=8)

0.95a+0.95b=7.60     Eqn 3

Subtracting Eqn 3 from Eqn 2

(0.95a+1.10b)-(0.95a+0.95b)=8.05-7.60

0.95a+1.10b-0.95a-0.95b=0.45

0.15b = 0.45

Dividing both sides by 0.15

[tex]\frac{0.15b}{0.15}=\frac{0.45}{0.15}\\b = 3[/tex]

Hence,

Sabrina bought 3 pounds of bananas.

If X = random variable

then, the standard deviation of the sampling distribution of X = [tex]\dfrac{\sigma}{\sqrt{n}}[/tex]

A.

GIven: [tex]\sigma= 1.2, \n= 6[/tex]

The standard deviation of the sampling distribution of X = [tex]\dfrac{1.2}{\sqrt{6}}=0.4899[/tex]

B. Let n be the sample size,

[tex]0.325=\dfrac{1.2}{\sqrt{n}}\\\\\Rightarrow\ \sqrt{n}=\dfrac{1.2}{0.325}\\\\\Rightarrow\ \sqrt{n}=3.69230769231\\\\\Rightarrow\ n= (3.69230769231)^2=13.6331360947\approx 14[/tex]

Hence, the required sample size = 14

Answer:

the group rents is 11 person tubes and there is 4 cooler tubes

Step-by-step explanation:

The computation is shown below:

The equation are as follows:

x + y = 15

y = 15 - x

And, the cost of person tube is $20

The cost of the cooler tube is $12.50

The total spending is $270

Now the equation is

20x + 12.50y = 270

Now put the value of y in the above equation

20x + 12.50(15 - x) = 270

20x + 187.50 - 12.50x = 270

20x - 12.50x + 187.50 = 270

7.50x + 187.50 = 270

7.50x = 270 - 187.50

7.50x = 82.50

x= 11

Now put the value of y in any of the equation

y = 15  - 11

= 4

So, the group rents is 11 person tubes and there is 4 cooler tubes

Answer:  Choice C.  y = (-1/2)x+7

=========================================================

Explanation:

The slope of the graphed line is -1/2 because we drop down 1 unit on the y axis each time we move to the right 2 units along the x axis. We could apply the slope formula for any two points on the diagonal line to also get a slope of -1/2.

The slope formula is m = (y2-y1)/(x2-x1).

Any two parallel lines have the same slope, but different y intercepts. So the parallel line will also have slope -1/2. Right away we can see the answer must be choice C. This is the only equation with slope -1/2 of the choices given.

Recall that slope intercept form y = mx+b has m as the slope. Not to be confused with the label m of the graphed line.

Note how plugging x = 6 into the equation for choice C leads to...

y = (-1/2)*x + 7

y = (-1/2)*6 + 7

y = -3 + 7

y = 4

Showing that (x,y) = (6,4) is on the equation y = (-1/2)x + 7. This confirms the answer.

---------------------------

Let's say we didn't have multiple choice answers to pick from, and instead it was fill in the blank. To find the y intercept b, we can do the following

y = mx+b

y = (-1/2)x + b ... plug in given slope m = -1/2

4 = (-1/2)*6 + b .... plug in the given point (x,y) = (6,4)

4 = -3 + b

4+3 = -3+b+3 ... adding 3 to both sides

7 = b

b = 7

Knowing that m = -1/2 and b = 7, we can update y = mx+b into y = (-1/2)x+7

Putting values

Answer:

The answer is below

Step-by-step explanation:

A football team scored 3 touchdowns, 3 extra points, and 4 field goals.  

a. Write an expression to represent the total points the football team scored.  

b. Write another expression that is equivalent to the one written above.  

c. If each touchdown is worth 6 points, each extra point is 1 point, and each field goal is 3 points, how many total points did the team score?  

Solution:

a) Let t represent the number of points for a touchdown, e represent the number of points for the extra point and f represent the number of points for a field goal.

Total points = 3(t) + 3(e) + 4(f) = 3t + 3e + 4f

b) Total points = 3t + 3e + 4f   OR

Total points = t + t + t + e + e + e + f + f + f + f  OR

Total points = 3(t + e) + 4f

c) Total points = 3(t + e) + 4f = 3(6 + 1) + 4(3) = 3(7) + 4(3)

Total points = 21 + 12 = 33 points

The sum of the points the team has from different point gaining options

give the total number of points the team scores.

Reasons:

The number of touchdowns by the football team, t = 3

Number of extra points by the football team, e = 3

Number of field goals by the team, f = 4

Therefor, the total number of points, P = 3·t + 3·e +4.f

The specified editor is an equation editor, which can be used to write mathematical equations.

Using an equation editor, we have;

[tex]\mathrm{The \ total \ points \ the \ football \ team \ scored } = 3 \cdot t + 3 \cdot e + 4 \cdot f[/tex]

Answer/Step-by-step explanation:

a.) Service A charges of 40 cents to pick you up is the initial value (y-intercept). Form the graph, the line that has a y-intercept of approximately 40 cents is line m.

Also, the initial value of line l is $1.10 from the graph, which is the pick up cost that Service B charges. Therefore,

Line m = Service A

Line l = Service B

b.) The additional charge of service B = the slope of line l. Let's calculate the slope to see if it's greater than or less than 30 cents per mile of the trip.

Using two points on line l, (0, 1.10) and (7, 2.5)

Slope = change in y/change in x = (2.5 - 1.10)/(7 - 0)

= 1.4/7 = 0.2

Additional charge per mile for service B is $0.2 = 20 cents.

Therefore we can conclude that the additional charge per mile for service B is less than 30 cents/mile of the trip.

The coordinates of the vertices after the dilation by a scale factor 1/5 centered at the origin  will be:

Step-by-step explanation:

We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.

If the scale factor > 1, the image is enlarged

If the scale factor is between 0 and 1, it gets shrunk

If the scale factor = 1, the object and the image are congruent

Rule to calculate the dilation by a scale factor 1/5 centered at the origin

P(x, y) → P'(1/5x, 1/5y)

Here, P'(1/5, 1/5y) is the image of P(x, y).

Given the vertices of the triangle UVW

U (-5, -10)

V (0, -10)

W (-5, 10)

so

Rule to calculate the dilation by a scale factor 1/5 centered at the origin

P(x, y) → P'(1/5x, 1/5y)

U (-5, -10) → U'(1/5(-5), 1/5(-10))  → U'(-1, -2)

V (0, -10) → V'(1/5(0), 1/5(-10))  → V'(0, -2)

W (-5, 10) → W'(1/5(-5), 1/5(10))  → W'(-1, 2)

Therefore, the coordinates of the vertices after the dilation by a scale factor 1/5 centered at the origin  will be:

Step-by-step explanation:

From the question, we are given that the ratio of the number of adults to the number of children at the resturant is 3:7.

The choices below that represent an equivalent ratio goes thus:

A: 6:14

This can be represented as: 6/14. The common factor is 2 and we reduce to lowest term which would be: = 3/7 = 3:7

This is an equivalent ratio.

B: 8:12

This can be represented as: 8/12. The common factor is 4 and we reduce to lowest term which would be: = 2/3 = 2:3

This is not an equivalent ratio.

C: 15:35

This can be represented as: 15/35. The common factor is 5 and we reduce to lowest term which would be: = 3/7 = 3:7

This is an equivalent ratio.

D: 21:9

This can be represented as: 21/9. The common factor is 3 and we reduce to lowest term which would be: = 7/3 = 7:3

This is not an equivalent ratio.

E: 30:70

This can be represented as: 30/70. The common factor is 10 and we reduce to lowest term which would be: = 3/7 = 3:7

This is an equivalent ratio.
