Answer by JKismyhusbandbae: expression 2 and expression 1
Look at the four expressions. Simplify any expressions that can be simplified to see which two are equivalent.
8v × 30v = ( 8 × 30) × ( v × v) = 
Since expression 2 can be simplified to expression 1, they are equivalent.
Answer:
- y= 7
- y= -3
- y= -4
- y= -8
Step-by-step explanation:
y= -5x+1
=-5.-1+1
=7

Answer:
Around 0.73% of adults in the USA have stage 2 high blood pressure
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean
and standard deviation
, the z-score 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 p-value, we get the probability that the value of the measure is greater than X.
Mean of 121 and standard deviation of 16.
This means that 
Around what percentage of adults in the USA have stage 2 high blood pressure
The proportion is 1 subtracted by the p-value of Z when X = 160. So



has a p-value of 0.9927.
1 - 0.9927 = 0.0073
0.0073*100% = 0.73%
Around 0.73% of adults in the USA have stage 2 high blood pressure
Answer:
243 students' favorite color is red
Step-by-step explanation:
if 55% of the students said their favorite color was blue, then 45% chose that red was their favorite color
we can get 45% of 540 using a cross-multiplication equation
45% is 45/100
45/100 is to ?/540
the (?) represents the value of students who chose red as their favorite color (we do not know this but we can figure it out using cross-multiplication)
45 times 540 is 24300
24300/100 = 243.
