Answer:
C= 11
Explanation:
Answer:
H0: p = 0.078
Ha: p ≠ 0.078
Step-by-step explanation:
The researchers say that the rate is about 7.8%, or 0.078 as a decimal. That makes that the null hypothesis because using "is" in math is the same as saying "equals" and the null hypothesis always has the statement of equality in it. The reason there is a not equals to sign in the alternate is for this reason as well. The researchers say it is about that amount, not more or less than that amount. So it makes this a 2 tailed test. If the amount is significantly higher or lower, then we might have to reject the null hypothesis depending on the outcome of the test.
Solution:
X°+68°+(x-24)°=180°
Or,2x°-24°=180°
Or,x=180°
now by puttin' the value of x we get,
<A=180°
<B=68°
<C=156°
Answer:
B
Step-by-step explanation:
Since both angles together need to equal 180, set up your formula as
(x+30)+(x+10)=180
2x+40=180
Answer:
Option A
Step-by-step explanation:
Area of the given figure = area of triangle + area of rectangle
A = side x height/2 + width x length
= 5 x (8-1-2)/2 + 5 x 8
= 52.5 in2
