I know you have 1 and 3 right but I'm sorry about not knowing the rest.
Step-by-step explanation:
A- 207 multiple 460 by 0.45
B- if 50 percent is 40 just multiply 40 by 2 its 80
C suppose you own a hot dog wagon and sell the following:
10 hot dogs in the morning
30 hot dogs in the afternoon
The number of hot dogs you sell in the afternoon is 300% of the number you sold in the morning. It’s three times as many.
A Z-score helps us to understand how far is the data from the mean. The Z-score of the learner for ACT is 2.1154, while for SAT is 2.1.
<h3>What is Z-score?</h3>
A Z-score helps us to understand how far is the data from the mean. It is a measure of how many times the data is above or below the mean. It is given by the formula,
Z = (X-μ)/σ
Where Z is the Z-score,
X is the data point,
μ is the mean and σ is the standard variable.
Given the mean for the ACT score is 21, while the standard deviation is 5.2, therefore, the Z-score for the ACT composite score will be,
Z = (32-21)/5.2 = 2.1154
Similarly, given the mean for the SAT score is 516, while the standard deviation is 116, therefore, the Z-score for the SAT composite score will be,
Z = (760-516)/116 = 2.1
Hence, the Z-score of the learner for ACT is 2.1154, while for SAT is 2.1.

Answer:
< BCA = 70
Step-by-step explanation:
The complete central angle of a circle is 360 degrees. The given portion is 250 degrees.
What is left over? BOA = 360 - 250 = 110
Tangents always meet the radius at 90 degrees. Since there are two tangents <CAO = <BAO = 90 degrees.
So piecing it all together, the equation becomes
<BAO + CAO + BAO + ACB = 360
110 + 90 + 90 + <ACB = 360
290 + <ACB = 360
<ACB + 290 - 290 = 360 - 290
ACB = 70 degrees
Answer:
If I were to say It would be 20-25 or 25-30 I think its 23
