Let's solve for a
ab+c=d
Add -c to both sides
ab+c+-c=d+-c
ab=-c+d
Divide both sides by b
ab/b=-c+d/b
a= -c+d/b
I hope that's help ! Good night .
Answer:
4 14/15
Step-by-step explanation:
8x + 2x + 5x = 180
15x = 180
x = 180/12
x = 12
m∠1 = 8x = 8*12 = 96°
m∠2 = 2x = 2*12 = 24°
m∠3 = 5x = 5*12 = 60°
The solution to the Questions are
- The alternate hypothesis demonstrates that there are two possible outcomes for the test.
- Decision rule: If z > 2.05 or z<-2.05, reject H0
- The two-tailed nature of the test is shown by the alternative hypothesis.
- The result of the test yields the following P-value: 0.0096
<h3>What is the alternate hypothesis?</h3>
(a)
The alternate hypothesis demonstrates that there are two possible outcomes for the test.
(b)
Here we have

(b)
Here the test is two-tailed. So for
, the critical values of the z-test are -2.05 and 2.05.
Decision rule: If z > 2.05 or z<-2.05, reject H0
(c)
Test statistics will be

z=2.59
(d)
The two-tailed nature of the test is shown by the alternative hypothesis.
(e)
The result of the test yields the following P-value: 0.0096

Answer:
35
Step-by-step explanation:
70 × 0.5 = 35
or
50% = 1/2
so
70/2 = 35
