Answer:
0.42074
Step-by-step explanation:
In this question, we are asked to calculate the probability that a car will get less than 21 miles per gallon.
This is P(x < 21)
z = 21-22/5 = -1/5 = -0.2
Therefore the probability of getting less than 21 miles per gallon will be;
P(x<21) = P (z < -0.2)
= 0.42074
Answer:x = 7.667
Step-by-step explanation:
3x - 8 = 15
+ 8 = 23
3x = 23
divide 3 by 3 and 23 so you get x by itself
answer = 7.667
Answer:y= -2/5x-3
Step-by-step explanation:
It's actually pretty simple, all you gotta do is flip the fraction around so if it is 5/2x now is 2/5, and then change the sign, since it was positive now it's negative
Answer:
No
Step-by-step explanation:
Scientific notation has to be a number between 1 and 10 times 10 to the something power. 10.2 is not between 1 and 10
Let's solve your equation step-by-step.
x+78=90
Step 1: Subtract 78 from both sides.
x+78−78=90−78
x=12
