Hi!

<h3>The simplest way to find out if they're equal is by solving each of them. </h3><h3>Imagine a number line. </h3>
  • -7 + 9

-7 moves to the right 9 times, and lands on 2.

  • -9 + 7

-9 moves to the right 7 times, and lands on -2.

<u>So, does -7 + 9 = -9 + 7?</u>

<u>Or we could say, does 2 = -2?</u>

<h2>The answer is no. This is false. </h2>

Hope this helps! :)

For a random sample of Harvard University psychology majors, the responses on political ideology had a mean of 3.18 and standard
Nutka1998 [239]

Answer:

From the test give in the question it is obvious that  there is enough evidence to show that population mean varies for vegetarian and non-vegetarian

The P-value helps affirm the null hypothesis claims,The P-value attains  values relatively as large as that which exists in the sample given,if the null hypothesis is right

Step-by-step explanation:

From the question we are told that

Sample mean \=x_1=3.18

Standard deviation \delta_! =1.72

Sample size n_1 =51

Sample mean \=x_2=2.22

Standard deviation \delta_2 =0.67

Sample size n_2=20

Generally this is a two tailed test

therefore

   Null hypothesis  = h_0 :P_v_e_g= P_n_o_n_v_e_g

  Alternative hypothesis H_a : P_v_e_g \neq  P_n_o_n_v_e_g

From the test give in the question it is obvious that  there is enough evidence to show that population mean varies for vegetarian and non-vegetarian

The P-value helps affirm the null hypothesis claims,The P-value attains  values relatively as large as that which exists in the sample given,if the null hypothesis is right

Answer:

w=3 1\4

Step-by-step explanation:

A=LxW

a=14 1\12

l=4 1\3

w=?

14 1\12=4 1\3 x w

14 1\12 divided by 4 1\3=13\4=3 1\4

w=3 1\4

Find the measure of angle B<br> A.95<br> B.48<br> C.15<br> D.12<br> E.84
ryzh [129]

Answer:

<h2>E)   84</h2><h2 />

Step-by-step explanation:

side AB is congruent to side AX

this means that the angle ∠A = 4x is the same angle as ∠Z

therefore ∠A = ∠Z = 4x

inside angle of a triangle = 180

∠A + ∠B + ∠Z = 180

4x + 7x + 4x = 180

15x = 180

x = 180/15

x = 12

now substitute x = 12 into angle B

∠B = 7x

∠B = 7 (12)

∠B = 84

therefore, the answer is E)  84
