Hello, I need help with this question, Brainliest will be awarded to the first correct answer.

Akimi4 [234]

Answer:No

Step-by-step explanation:

it isn't a function because say u make a vertical line right through the sideways parabola (in purple), the line will cross two points from the parabola, if it only crossed through one point then it would be a function

The minimum amount of wrapping material needed to cover a biscuit would be equal to the biscuit area. The biscuit is spherical/circle, so the area would be <span>using circle formula. If the area is 200,96, the radius would be:
circle area = </span><span>π * r * r
200.96= 3.14 * r^2
r^2=</span>200.96/3.14
r= √64= 8

The diameter would be:
diameter = radius *2
diameter= 8*2= 16

Answer:

The decision rule is

Reject the null hypothesis

The test statistics is $t = -2.699$

Step-by-step explanation:

From the question we are told that

The first sample size is $n_1 = 15$

The mean at first deployment is $\= x _1 = \$ 150 000$

The standard deviation is $s_1 = \$ 40000$

The second sample size is $n_2 = 25$

The mean at second deployment is $\= x_2 = \$ 180000$

The standard deviation is $s_2 = \$ 30 000$

The null hypothesis is $H_o : \mu_1 = \mu_2$

The alternative hypothesis is $H_a : \mu_1 \ne \mu_2$

The level of significance is $\alpha = 0.05$

Generally the degree of freedom is mathematically represented as

$df =n_1 + n_2 -2$

=> $df =40 -2$

=> $df =38$

Generally the pooled variance is mathematically represented as

$s_p^2 = \frac{x(n_1 -1) s_1^2 + (n_2 - 1)s_2^2}{df}$

=> $s_p^2 = \frac{(15 -1) 40000^2 + (25 - 1)30000^2}{38}$

=> $s_p^2 = 1.1579 * 10^{9}$

Generally the test statistics is mathematically represented as

$t = \frac{ \= x_1 - \= x_2 }{\sqrt{s_p [\frac{1}{n_1} + \frac{1}{n_2} ]} }$

=> $t = \frac{ 150000 - 180000 }{\sqrt{1.11579 *10^{9} [\frac{1}{15} + \frac{1}{25} ]} }$

=> $t = -2.699$

Generally from the t distribution table the probability corresponding to the t statistics value to the left is

$t_{-2.699 , 38} = 0.00516046$

Generally the p -value is mathematically represented as

$p-value = 2* t_{-2.699, 38}$

=> $p-value = 2* 0.00516046$

=> $p-value = 0.01032$

From the obtained value we see that the $p-value < \alpha$ hence

The decision rule is

Reject the null hypothesis

3/4x=2x−5<br><br> NEED ANSWER WITHIN THE NEXT HOUR PLEASE GIVING 20 PTS!!!

Andrews [41]

Answer:

x = 4

Step-by-step explanation:

1. Write the equation

3/4x = 2x - 5

2. Get the variables on the same side

Let's subtract 2x! Now, since math is a veryyy jealous subject, you're going to do it on the other side too!

-1.25x = -5

3. Divide both sides by -1.25

x = 4

Thank you for the points!!!
