Answer: D

Step-by-step explanation: its best you can get to the a quotient (from Latin: quotiens "how many times", pronounced) is a quantity produced by the division of two numbers. The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division (in the case of Euclidean division), or as a fraction or a ratio (in the case of proper division). For example, when dividing 20 (the dividend) by 3 (the divisor), the quotient is 6 in the Euclidean division sense, and 62/3 in the proper division sense.

Answer:

[tex]A=160ft^2[/tex]

Step-by-step explanation:

Length of yard [tex]l=37ft[/tex]

Width of yard [tex]w=43ft[/tex]

Walk [tex]l_w=2ft[/tex]

Generally the perameter of the fence P is mathematically given by

[tex]P=l+w[/tex]

[tex]P=37+43[/tex]

[tex]P=80[/tex]

Generally the equation for area of walk is mathematically given by

[tex]A=P*l_w[/tex]

[tex]A=80*2[/tex]

[tex]A=160 ft^2[/tex]

Therefore area of walk is

[tex]A=160ft^2[/tex]

Answer:

The surface area is 286.5in.

Step-by-step explanation:

7.5 * 11.5 = 86.25 * 2 = 172.5in for two big rectangles

7.5 * 3 = 22.5 for little rectangle

11.5 * 3 = 34.5 * 2 = 69 for two medioum rectangles

7.5 * 3 = 22.5 for the smallest rectangle

22.5 + 69 + 22.5 + 172.5 = 286.5 in SA

Answer:B

y=13cos(1/13x)+13

Step-by-step explanation:

The cosine equation to model the height of the red spot over a distance you ride is y = 13 cos (x/13) + 13. Then the correct option is B.

It is a function that repeats itself in a particular time interval.

You ride through some wet paint on your bike, creating a red spot on the tire.

Write a cosine equation to model the height of the red spot over the distance you ride.

Your bike tire has a radius (r) of 13 inches.

The period is the circumference of the tire (2πr).

The cosine equation is given as

y = A cos (Bx + C) + D

Where

A = the amplitude

B = time period

C = phase difference

D = shifting of central line

Then we have the diagram

A = 13

B = 1/13

C = 0

D = 13

Then the equation will be

[tex]\rm y = 13 \cos (\dfrac{1}{13}x - 0 ) + 13\\\\y = 13 \cos (\dfrac{x}{13} ) + 13[/tex]

The smallest sample size needed to construct a 99% confidence interval with a margin of error of no more than ±1 inch is 39.

The margin of error (E) for a confidence interval is described as:

E = z × (σ / √n)

where:

E is the desired margin of error

z is the z-score corresponding to the desired confidence level (in this case, 99% confidence level)

σ is the population standard deviation

n is the sample size

In this case, the margin of error is no more than ±1 inch, so E = 1 inch.

Now, determine the z-score corresponding to a 99% confidence level using a standard normal distribution table or statistical software.

For a 99% confidence level, the z-score is approximately 2.576.

Plugging in the known values into the margin of error formula,

1 = 2.576 × (2.4 / √n)

To solve for n, rearrange the formula as follows:

√n = (2.576 × 2.4) / 1

√n = 6.1824

n = (6.1824)²

n ≈ 38.16

Therefore, the smallest sample size needed to construct a 99% confidence interval with a margin of error of no more than ±1 inch is 39.

This question doesn't make sense.

How is the longer side 7 when the shorter side is 15?

Here's your answer anyway:

82.5

Step-by-step explanation:

Answer:

you will have to find the slope in the y= mx+b form.

you can find the slope also by looking at the graph and looking at the rise over run

so it's a square which means all of the sides are equal.

that means x+7=3x+1

      subtract 1 from both sides

x + 6 = 3x

      subtract x from both sides

6 = 2x

      divide both sides by 2

3 = x

you can do the same for y

2y - 1 = -3y + 14

    add 3y to both sides

5y - 1 = 14

     add 1 to both sides

5y = 15

      divide both sides by 5

y = 3

Answer:

23

Solving steps

We know x= -10-15y, so we can subtract it to the equation above

x = -10-15y

2x+5y=35

2(-10-15y) + 5y = 35

(Refer to the 1st image to solve for y)

Y = -11/5

We now know y= -11/5, so we can subtract it to the equation for x.

Y = -11/5

x = -10-15y

x = -10-15(-11/5)

(Refer to the 2nd and 3rd image to solve for x) (Make sure to look at both images first before writing something down)

x = 33 - 10

x = 23

Please give brainlliest thanks! :)

This problem can take a while if you cannot observer the answer quickly.

First of all we can see that 32=2*2*2*2*2=2^5

243, if you don't know its actually is 3^5

Now we can see that this turns into...

- 2^5/3^5

since the 5th power doesn't change the sign of the original number, we can put the negative in the ( ), if you don't know what I mean look below

(-3)^2=9 Positive

(-3)^3=-27 Negative since its to the odd power it keeps the sign.

This problem can be simplified to.

(-2/3)^5

And this is the answer :D

Answer:

m is equal to -1 ± 2√3, which is approximately equal to 2.46 and -4.46

Step-by-step explanation:

-4m² + 2m - 11 = -5m²

m² + 2m - 11 = 0

m² + 2m + 1 = 12

(m + 1)² = 12

m + 1 = ± √12

m = -1 ± 2√3
