Answer:
$100
Step-by-step explanation:
20%+30% = 50% off
50/100 = 1/2
200*1/2 = $100
Suppose y varies inversely with x and that y=2 when x=8 What is an equation for this inverse variation?
B. y= 2/8x
The answer is B. 0.75 because that’s what it would be equal to in decimal form.
Answer:
0.01
Step-by-step explanation:
Using the z score formula
z = (x-μ)/σ,
where x is the raw score = 135
μ is the population mean = 100
σ is the population standard deviation = 15
z = 135 - 100/15
z = 2.33333
P-value from Z-Table:
P(x<135) = 0.99018
P(x>135) = 1 - P(x<135)
P(x > 135) = 1 - 0.99018
= 0.0098153
Approximately to 2 decimal places
= 0.01
Therefore, the proportion of the population for the following IQ score of 135 is 0.01
Answer:
1. 3/10 is equal to .3 or 30%
2. 7/10 is equal to .7 or 70%
3. The distributive property of multiplication over addition can be used when you multiply a number by a sum. For example, suppose you want to multiply 3 by the sum of 10 + 2. 3(10 + 2) = (30 +20) you can distribute the value outside of the parentheses to the values inside.
