Answer:
ok so this can be represented as
7.75x+675=1062.50
-675
7.75x=387.5
divide by 7.75
x=50
Hope This Helps!!!
Answer: There is none.
Step-by-step explanation:
There is no proportional relationship between Celsius and Fahrenheit because for a proportional relationship to exist, the two variables need to have an equivalent ratio between them which would ensure that their values vary constantly when they are either divided or multiplied.
In other words, only the arithmetic operations of multiplication and division should be present. In the above there is an additive operation which renders the two variables being Fahrenheit and Celsius, non-proportional.
Answer:
The mean is
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
What is the mean of this normal distribution if the probability of scoring above x = 209 is 0.0228?
This means that when X = 209, Z has a pvalue of 1-0.0228 = 0.9772. So when X = 209, Z = 2.
The mean is
Your percent is going to be <span>-203.008</span>
Step-by-step explanation:
a) 2/5 × 5/7 = 10/35 ➡ 2/7 (if needed to simplify)
b) 16/25 × 2/4 = 32/100 ➡ 8/25
c) 15/6 ÷ 3/15 ➡ 15/6 × 15/3 = 25/2
d) 4/11 × 12/9 = 16/33
e) 3/5 × 7/12 = 7/20
f) 9/27 × 2/6 ➡ 9/27 × 6/2 = 3
