GEOMETRY Write and solve an equation to find the value of x so that it figures have the same area.

Answers

Answer:

C. x=7 and the expression is (5+x)9=x*(15 3/7)

Step-by-step explanation:

The width of the first shape is 5+x and the length is 9

The width of the second shape is x and the length is 15 3/7

You want the same area of the figures, so they are equal. And the formula for the area of a rectangle is l*w. So...

(5+x)9=x*(15 3/7)

45+9x=(108/7)x

315+63x=108x

63x-108x=-315

-45x=-315

x=7

So, your answer is C.

The number of apples left to eat are equivalent to 4.

What is percentage?

In mathematics →

a percentage is a number or ratio expressed as a fraction of 100.it is often denoted using the percent sign "%".

Given is that you have 5 apples to eat during the week and you eat 20% on the first day.

Assume the number of apples left are {x}. So, we can write -

{x] = 5 - 20% of 5

{x} = 5 - (20/100) x 5

{x} = 5 - 1

{x} = 4

Therefore,

Intro

Answers

Answer:

1:4

Step-by-step explanation:

If x is the volume of 30% acid solution, and y is the volume of 5% acid solution, then:

0.30x + 0.05y = 0.10(x + y)

0.30x + 0.05y = 0.10x + 0.10y

0.20x = 0.05y

x/y = 0.05/0.20

x/y = 1/4

A primatologist believes that rhesus monkeys possess curiosity. She reasons that, if this is true, then they should prefer novel stimulation to repetitive stimulation. An experiment is conducted in which 12 rhesus monkeys are randomly selected from the university colony and taught to press two bars. Pressing bar 1 always produces the same sound, whereas bar 2 produces a novel sound each time it is pressed. After learning to press the bars, the monkeys are tested for 15 minutes, during which they have free access to both bars. The number of presses on each bar during the 15 minutes is recorded. The resulting data are as follows:What is the alternative hypothesis? In this case, assume a nondirectional hypothesis is appropriate because there is insufficient empirical basis to warrant a directional hypothesis. What is the null hypothesis?

Mean of difference =[tex]\frac{Sum}{10}=\frac{123}{10}=12.3[/tex]

Standard deviation s =[tex]\sqrt{\frac{(x_i-\bar{x})^2}{n}}=8.93[/tex]

Null Hypothesis : mean of difference scores is 0 : [tex]H_0:\mu=0[/tex]

Alternate Hypothesis : mean of difference scores is different from 0 : [tex]H_a:\mu \neq 0[/tex]

We will use t test for unpaired

[tex]t = \frac{x-\mu}{\sqrt{\frac{s^2}{n-1}}}\\t = \frac{12.3-0}{\sqrt{\frac{8.93^2}{10-1}}}\\t=4.13[/tex]

Level of significance (two tailed) =[tex]\alpha = 0.05[/tex]

Degree of freedom = n-1 = 10-1 =9

Using calculator

The p-value is .002559.

p value < α

So ,we reject null hypothesis

So, It is statistically significant that mean of difference scores is different from 0
