Answer:
y = 8
Step-by-step explanation:
simplify=9y-12=60
add 12 9y=72
divide 9y/9= y= 72/9=8
please mark branliest i really need it.
Answer:
Step-by-step explanation:
Assuming a normal distribution for the amount spent by Canadian households for high-speed broadband access, the formula for normal distribution is expressed as
z = (x - u)/s
Where
x = amount spent by the Canadian households.
u = mean amount spent monthly.
s = standard deviation
From the information given,
u = $80.63 CDN
s = $27.32 CDN
We want to find the probability that the average amount will exceed $85. It is expressed as
P(x greater than 85) = 1 - P(x lesser than or equal to 85)
For x = 85
z = (85 - 80)/27.32 = 0.18
Looking at the normal distribution table, the corresponding z score is 0.57142
P(x greater than 85) = 1 - 0.57142 = 0.43
For this case, the first thing we should do is define a variable.
- <em>x: percentage of plant growth
</em>
The formula that models this problem is given by:
Substituting values we have:

Answer:
The percent increase in the height of the plants is 100%
Answer:
8/17
Step-by-step explanation:
first find hypotenuse which is 34
then to get sine it is opposite/hypotenuse
opposite ÷ hypotenuse
16/34
8/17
