Answer:
z-score
Step-by-step explanation:
Since we are given the mean and standard deviation of a national test (whole population) it is fair to assume a large population size, and the use of the z-score would be more appropriate, since the z-score is used for the standardization of population data, while the t-score is recommended for samples or small populations.
Answer:
530 m²
Step-by-step explanation:
First of all we need to label the missing sides ,please check the figure I provided for that :
x = 37 - (10+ 15) = 37 - 25 = 12
z = 10
y = 2 × 10 = 20
The shade does area = area of the whole rectangle − the white area
= 37 × 20 − [ (15×20)÷2 + (10×12)÷2 ]
= 740 − [ 150 + 60 ]
= 740. − 210
= 530
To do this question I recommend dividing each number by the lowest prime number you can each time.
36/2=18
18/2=9
9/3=3
Since 3 is prime we stop there. The prime factors of 36 are therefore 2,2,3, and 3. I would write this as 36=2^2x3^2
22 is simpler as it is just 2x11
Answer: y = 5(x - 3)² - 2
<u>Step-by-step explanation:</u>
Vertex form: y = a(x - h)² + k <em>where (h,k) is the vertex and "a" is the vertical stretch</em>
Given (h, k) = (3, -2) and (x, y) = (2, 3), we can find the a-value.
3 = a(2 - 3)² - 2
3 = a(1) - 2
<u>+2</u> <u> +2 </u>
5 = a
Next, input the vertex and the a-value into the vertex equation.
y = 5(x - 3)² - 2
Answer is √35 (square root of 35)
Reason: square root of 35 (which is = 5.9160797831.....) which is a non-terminating decimal, which means it is irrational.
An irrational number is any real number that cannot be expressed as a simple fraction or terminating decimals. There are many answers to this question.
