btw the answer is

(12x+6)

Answer:

10 and -5

Step-by-step explanation:

x + y = 5

xy = -50

y = 5 - x

x(5-x) = -50

5x - x^2 = -50

x^2 - 5x - 50 = 0

from there on we can solve the classic way

[tex]\Delta = (-5)^2 - 4\cdot1\cdot(-50) = 25 + 200 = 225\\\sqrt{\Delta} = 15\\x_1 = \frac{5 - 15}{2} = -5\\x_2 = \frac{5+15}{2} = 10\\y_1 = 5 - x_1 = 10\\y_2 = 5 - x_2 = -5[/tex]

Everything checks out.

Answer:

-5 × 10 = -50

-5 + 10 = 5

Answer:

60%

Step-by-step explanation:

If there are 250 tables you can multiply it by 4 to work with 1000. This means you have to multiply the other table cloth numbers. 150 x 4 = 600. 100 x 4 = 400. Once you simplify you can get 40 white and 60 red out of 100.  60/100 = 60%.

Answer:

a. 1.97 is a statistic

b. t test is = 1.32

p value = 0.186

c. there is not enough evidence to support our claim

Step-by-step explanation:

a. 1.97 is not a parameter it is a statistic. It is the standard deviation of the sample. we represent this with the symbol s.

b. we are claiming that the mean hours that are spent watching television is different from 2.75

we form our hypothesis as:

h0; u = 2.75

h1: u not equal to 2.7

t stat = barx - u/s/√n

= 3.01-2.75/(1.97/√100)

= 0.26/(1.97/10)

= 0.26/0.197

= 1.32

we get p value

n = 100

df = 100-1 = 99

using t distribution, pvalue = 0.1899

c. the p value is higher than our alpha level here

0.189 > 0.05, so we fail to reject H0. our conclusion is that there is not enough evidence to show that μ is different from 2.75

Answer: 146

Step-by-step explanation: Divide 7300 by 50

Answer:

b = 1460

Step-by-step explanation:

50b = 7,300

the steps are easy and simple- Divide 50 on each side

50b/50 = 7300/50

this will isolate b and give it's answer

b = 1460

Answer:

Step-by-step explanation:

1.20 divided by 0.08 is 15

0.08 x 15= 1.20

Answer:

P(0) = 4C0 * 0.75⁰ * 0.25⁴ = 0.00390625 . = 0.004

P(1) = 4C1 * 0.75¹ * 0.25³ = 0.046875 . . . = 0.047

P(2) = 4C2 * 0.75² * 0.25² = 0.2109375 . . = 0.211

P(3) = 4C3 * 0.75³ * 0.25¹ = 0.421875 . . . = 0.422

P(4) = 4C4 * 0.75⁴ * 0.25⁰ = 0.31640625 . = 0.316

Check:

P(0) + P(1) + P(2) + P(3) + P(4) = 1 . . . ok

Step-by-step explanation:

In response to the question, we may say that So the dimensions of the rectangular living room are 10 meters by 10 meters.

In Euclidean geometry, a rectangle is a parallelogram with four small angles. It may also be defined as a fundamental rule hexagon or one in which all of the angles are equal. Another alternative for the parallelogram is a straight angle. Four of the vertices of a square are the same length. A quadrilateral with four 90° angle vertices and equal parallel sides has a rectangle-shaped cross section. As a result, it is also known as a "equirectangular rectangle." A rectangle is sometimes referred to as a parallelogram due to the equal and parallel dimensions of its two sides.

Let's denote the length of the rectangular living room as "L" and the width as "W".

Perimeter = 2L + 2W = 40

L + W = 20

We also know that the area of the living room is 100 square meters.

Area = L x W = 100

L + W = 20 (equation 1)

L x W = 100 (equation 2)

We can solve for one of the variables in terms of the other in equation 1:

[tex]L = 20 - W\\(20 - W) x W = 100\\20W - W^2 = 100\\W^2 - 20W + 100 = 0\\where a = 1, b = -20, and c = 100.\\W = (-(-20) + \sqrt((-20)^2 - 4 x 1 x 100)) / 2 x 1\\W = (20 + \sqrt(400 - 400)) / 2\\W = 10\\L + 10 = 20\\L = 10\\[/tex]

So the dimensions of the rectangular living room are 10 meters by 10 meters.

Answer:

f=12.7

Step-by-step explanation:

Answer:

12.7

Step-by-step explanation:

To find f, we need to "reverse" the operation and do 8.6 + 4.1 which equals 12.7.

Double check: 12.7 - 4.1 = 8.6 which is true. Therefore, 12.7 = f.
