1. 30$ because 30% of $100 is 30$
2. 30%. 10% is 12•3
Given two coordinates point 1 as (-23,-14) and point 2 as(-18,2).
To find the midpoint we would use the formula below;
Where x1=-23, x2=-18, y1=-14, y2=2
We would substitute the values into the midpoint formula.
Therefore, the answer is
(4, -4) is the answer
-45<span>° is in quadrant IV and the point (4, -4) is the only point out of the points given that is also in quadrant IV</span>
Answer:
The minimum number of cups she must sell to reach her goal=43 cups
Step-by-step explanation:
Total earnings=Total Lemonade sales-Supplies expenditure
where;
Total earnings=$40
Total Lemonade sales=Price per cup×Number of cups sold(n)=(0.7×n)=0.7n
Supplies Expenditure=0.23 per cup=(0.23×n)=0.23n
Replacing;
40=0.7n+0.23n
Inequality; 0.7n+0.23n=40
Solving;
0.93n=40
n=40/0.93)=43 cups
The minimum number of cups she must sell to reach her goal=n=43 cups
Answer:
0.03 is the probability that for the sample mean IQ score is greater than 103.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 100
Standard Deviation, σ = 16
Sample size, n = 100
We are given that the distribution of IQ score is a bell shaped distribution that is a normal distribution.
Formula:
Standard error due to sampling =
P( mean IQ score is greater than 103)
P(x > 103)
Calculation the value from standard normal z table, we have,
0.03 is the probability that for the sample mean IQ score is greater than 103.
