Answer:

18

Step-by-step explanation:

x² = 16² + 30² - 2(16)(30)cos 30°

x² = 256 + 900 - 960(0.866)

x² = 1156 - 831.36

x² = 324.64

x = 18.02

Approx. 18

Answer:

18.01

Step-by-step explanation:

c^2=a^2+b^2-2abcos 30=

   = 16^2+30^2-2(16)(30)(cos30)             cos30=0.866

   = 1156-480√3 = 324.6156

c=√324.6156=18.01

Which algebraic expression represents “the class was divided into four equal groups”?
scZoUnD [109]

Answer:

\frac{w}{4}

Step-by-step explanation:

The algebraic expression states that

"The class we divided into four equal groups."

We have our expression right at the word of "divided", therefore the answer would be a division problem.

w over 4 fits this because it fits the expression, w - class and 4 - amount of groups.

4 + w - Would be the class added four groups

4w - The class multiplies four more groups

4 - w - Four groups was taken from the class

11Alexandr11 [23.1K]

y= mx+b

(16, -7) = (x,y)

2(16) - 3y = 12

32 - 3y = 12

32 - 12 = 3y

20/3 = y

6.6 = y

2x-3(-7) = 12

2x+21 = 12

2x = 12 - 21

x = -9/2

Insert the values into y = mx + b

solve for m and then solve for b

A consumer advocacy group wants to determine whether there is a difference between the proportions of the two leading automobile
podryga [215]

Answer:

The answer is "0.3206".

Step-by-step explanation:

H_0: p_1 = p_2\\\\H_a: p_1 \neq  p_2\\\\\hat{p_1} = \frac{X_1}{N_1} = \frac{53}{400} = 0.1325\\\\\hat{p_1}= \frac{X_2}{N_2} = \frac{78}{500}= 0.156\\\\\hat{p} = \frac{(X_1 + X_2)}{(N_1 + N_2)} = \frac{(53+78)}{(400+500)} = 0.1456

Testing statistic:

z = \frac{(\hat{p_1}- \hat{p_2})}{\sqrt{(\hat{p} \times (1-\hat{p}) \times (\frac{1}{N_1} + \frac{1}{N_2}))}}

=\frac{(0.1325-0.156)}{\sqrt{(0.1456\times (1-0.1456)\times (\frac{1}{400} + \frac{1}{500}))}}\\\\ = -0.99

Calculating the P-value Approach

\text{P-value}= 0.3206
