Answer:
The first answer choice, (-14) + 8
Step-by-step explanation:
1. Solve (-14) - (-8)
(-14) - (-8) = -6
2. Solve the answer choices
(-14) + 8= -6
14 - (-8)= 22
14 + (-8)= 6
(-14) + (-8)= -22
The answer is x=1
x^5=1
x=5[square]1
x=1
Say the base length is 8, and the height is 8. If you multiply it by 1/4, the new base length is 2. The formula for the area of a triangle is: A=1/2bh you take 1/2 of 2, which is 1, and you multiply by the height (8) to get 8 square units for the area. This is opposed to if you simply did the formula without multiplying by 1/4. If you avoided multiplying by 1/4, you would get A=(4)(8), which would get you 32 square inches for the area. So, in conclusion, multiplying the base by 1/4, gets you 1/4 the area.
Answer: 24
Step-by-step explanation:
36/3 = 12
This means that 12 is one third of the flower pots.
Since she uses two thirds, just multiply the answer by 2.
12x2 = 24, so 2/3 is 24
Therefore, Mary plants daisies in 24 flower pots.
Hope this helps!
This question is incomplete, the complete question is;
A certain organization reported the following scores for two parts of the scholastic Aptitude test ( SAT)
Evidence-based Reading and writing : 533
Mathematics : 527
Assume the population standard deviation for each part is σ = 100.
What is the probability a sample of 66 test takers will provide a sample mean test score within 10 points of the population mean of 533 on the Evidence-based Reading and Writing part of the test?
Answer: the required probability is 0.582
Step-by-step explanation:
Given that;
Population mean = 533
sample size n = 66
population standard deviation σ = 100
σ of x bar = 100/√66 = 12.3091
Normal distribution with mean 533 and SD of 12.3091
P( 523 <x< 543 )
Z = 10 / 12.3091
Z = 0.8124, -0.8124
P( z < 0 0.8124) - P( z < -0.8124) { from table}
⇒ 0.7910 - 0.2090
= 0.582
Therefore, the required probability is 0.582
