Answer:
b. area = 18 square units
Step-by-step explanation:
area of a triangle = 1/2 * base * height
area = 1/2 (6+3) + (6-2)
area = 1/2 * 9 * 4
area = 18 square units
therefore the answer is b.
20 with a number minus what will equal 9. ^_^
Answer:
The corresponding p - value will be is < 0.00001 which is less than 0.05
Step-by-step explanation:
Suppose p= 0.12 and n= 540 then the standard deviation can be taken out as √p(1-p)/n= √0.12(1-0.12)/540= 0.014
For the probability that the survey will provide a sample proportion within 6.03 of the population proportion
we will find the z statistic
z= p^-p/√p(1-p)/n
But √p(1-p)/n= 0.014 and p^-p= 6.03
Putting the values
z= 6.03/0.014= 430.71
The corresponding p - value will be is < 0.00001 which is less than 0.05
Answer:
B 9
Step-by-step explanation:
Use the rule of exponents for a division. To divide two powers with the same base, write the same base and subtract the exponents.

Now do it with your numbers.

Answer: B 9
Answer:
12.5
Step-by-step explanation:
a^2 + b^2 = c^2
a^2 + 10^2 = 16^2
a^2 + 100 = 256
a^2 = 256 - 100
a^2 = 156
a = 12.48 or 12.5
