Answer: 16 birds
Step-by-step explanation:
Acording to the info we know that: for every 1 squirrel there are 4 birds
=> the number of the birds if there were 15 squirrels: 15*4=60 (birds)
Answer: P(22 ≤ x ≤ 29) = 0.703
Step-by-step explanation:
Since the machine's output is normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = output of the machine in ounces per cup.
µ = mean output
σ = standard deviation
From the information given,
µ = 27
σ = 3
The probability of filling a cup between 22 and 29 ounces is expressed as
P(22 ≤ x ≤ 29)
For x = 22,
z = (22 - 27)/3 = - 1.67
Looking at the normal distribution table, the probability corresponding to the z score is 0.047
For x = 29,
z = (29 - 27)/3 = 0.67
Looking at the normal distribution table, the probability corresponding to the z score is 0.75
Therefore,
P(22 ≤ x ≤ 29) = 0.75 - 0.047 = 0.703
Answer:
-2
(The coordinate point is (0,-2))
Step-by-step explanation:
First, make an equation of the line.
Start off with finding the slope:
Slope = (13-1)/(5-1) = 12/4 = 3
Then solve for the y-intercept though substitution and simplification:
y=mx+b --> 1=3(1)+b --> 1=3+b --> b= -2
So the answer is -2.
Answer:
E. 55 hours.
Step by step:
Multiple $15x40, equals $600
Subtract $600 from $937.50, equals $337.50
50% more over 40 hours is $22.50
Divide $337.50 by $22.50, equals 15
Add 15 to 40, equals 45
So she worked 55 hours to get paid $937.50
Answer:
Time = distance/speed. T = 1,200,000,000/28,000. This can be cancelled to 1,200,000/28. Rounding 28 to 30 for the estimate, divide by another ten: 120,000. Then divide by the remaining 3 from 30: 120,000/3 = 40,000. It will take approximately 40,000 hours.
