Answer:
x=-2 y=3
Step-by-step explanation:
The substitution is basically given to you. Exchange x from the second equation with y-5
Once that is done and you combine the parentheses you get:
2y-10+y=-1
Add 10 on both sides of the equal sign
You get:
3y=9
Divide both sides by 3
You get:
y=3
To check your work you can substitute y in the second equation with 3 and solve it that way to get x=-2 (x equals negative two)
Answer:
<em>A.) There is a 3.4% chance that a random sample of 50 expectant mothers will have a mean age of 26.5 years old or greater if the mean age for a first time mother is 26 years old.</em>
Step-by-step explanation:
The mean age for a first time mother is assumed 26 years old (null hypothesis) and <em>p-value</em> of the sample mean (26.5 years ) is found as 0.034.
This is the probability of having first time mother mean age 26.5 or greater <em>under the assumption of null hypothesis. </em>
Answer:
y= 6
Step-by-step explanation:
A horizontal line means y = something ( the x value will change, but y remains the same)
In this case, the y value is 6
y= 6
Given :
Fresh Farm: $4.50 for 5 lbs
Fruit Garden: $1/5 for 1/3 lb
Mother Nature: $4 for 5 lbs
Country Market: $0.85 per pound
To Find :
Which store offers the lowest unit rate for cantaloupes, in dollars per pound.
Solution :
Dollar per pound of each store :
Fresh Farm : 4.50/5 = $0.9 per pound
Fruit Garden: (1/5)/(1/3) = $0.6 per pound
Mother Nature: 4/5 = $0.8 per pound
Country Market: $0.85 per pound
From above we can see that Fruit Garden offers lowest unit rate.
Hence, this is the required solution.
75% = 330 gumballs
Find 1%:
1% = 330 ÷ 75 = 4.4 gumballs
Find 100%:
100% = 4.4 x 100 = 440 gumballs.
Answer: 440 gumballs.
