Assuming the two angles are supplementary, the angle measuring x is equal to 33.75, and the angle measuring 3x+45 is equal to 146.25.
Step-by-step explanation:
x+(3x+45)=4x+45=180
4x+45=180
-45 -45
4x=135
÷3 ÷3
x=33.75
3x+45=146.25
Answer:
Probability that the cost will be less than $500 is 0.95994 .
Step-by-step explanation:
We are given that Money magazine reported that a visit to a hospital emergency room for something as simple as a sore throat has a mean cost of $348 with a standard deviation of $87.
Let X = cost of a hospital emergency room visit for this medical service
So, X ~ N(
)
The standard normal z score distribution is given by;
Z = 
~ N(0,1)
(a) Probability that the cost will be less than $500 = P(X < $500)
P(X < 500) = P( < 
) = P(Z < 1.75) = 0.95994 {from z table}
Therefore, the probability that the cost will be less than $500 is 0.95994 .
Answer:
its either -7 or 7 but im not super confidant in that answer but thats what makes sense to me
Answer:
19 weeks
Step-by-step explanation:
Given equation:
P = w
Where,
w = the number of weeks he has taken piano lessons
p = the total number of pieces he has learned
how many weeks of piano lessons will Lamar need before he will be able to play a total of 19 pieces?
Find w when p = 19
P = w
p = 19
Since P = w
19 = w
Therefore,
w = 19
Lamar need 19 weeks before he will be able to play a total of 19 pieces
The product of 4 and a number increased by 6 is 30 would be written like this;
4x + 6 = 30
