41.=30°
43.=60°
45.=60°
47.=30°
Answer:
44
Step-by-step explanation:
Parenthesis
Exponents
Multiply
Divide
Add
Subtract
First we need to do the work inside the parenthesis that are in the boxed parenthesis
3 + 1 = 4
4 * 5 = 20
Now we multiply
20 * 2 = 40
Now we add
40 + 4 = 44
Best Of Luck,
- I.A. -
So area=1/2 base times height
50=1/2 base times height
multiply both sides by 2
100=base times height
base=4height
100=4height times height
100=4height^2
divide 4
25=height^2
squarer root
5=height
subisute
base=4(5)
base=20
height=5
Answer:
C.-2.33
Step-by-step explanation:
We are given that
Significance level,
%=0.01
We have to find the critical value of z for a left-tailed test.
To find the critical value , we will use the z-table at significance level 0.01 for left-tailed test.
By using the z-table at significance level 0.01 for left-tailed test
The critical value of z at 1% significance level for left-tailed test
=-2.33
We get p-value by using z-critical value
P-value=0.0099<0.01
So, hypothesis test would be reject the null hypothesis at at 1% significance level.
Hence, the critical value of z=-2.33
Option C is true.
