r=24.5
now,
area=πr²
=22/7*(24.5)²

Dan loves to compete in triathlons. At a race a few months ago, he finished in 300 minutes. Yesterday, he completed another triathlon and finished in 306 minutes. What was the percent of increase in Dan's finishing time?
Answer:
2%
Step-by-step explanation:
If 300 minutes is 100%, how much percent is 306 minutes?
we need to use the rule of three
306 minutes x 100% / 300 minutes = 102%
Therefore the percent of the increase is 102%-100%= 2%

The sum of three consecutive integers is -561. What are the
integers?
I
Answer:
-188, -187, -186
Step-by-step explanation:
x + (x+1) +(x+2) will usually be the formula for questions like this. If there wer 4 consecutive numbers, you just add (x+3) and so on.
The three integers are:
x + (x+1) + (x+2) Simplify this :
3x+3 = -561 Get 3x by itself, subtract 3 on both sides:
-3 -3
3x = -564 Find x divide -564 and 3:
x = -188
-188 is the first number now you count up.
-188 is the first number, -187 is the second, -186 is the third.

Na'ilah is spinning 2 fair spinners. Which table shows all the possible outcomes of spinning both spinners
The possible outcomes of spinning both spinners is the sample space of the spinner
The possible outcomes are A1, A2, A3, B1, B2 and B3
How to determine the possible outcomesThe question is incomplete, as the number of sections in each spinner is not given.
Assume the sections on the first spinner are A and B, while the sections on the second spinner are 1, 2 and 3.
The possible outcomes would be: A1, A2, A3, B1, B2 and B3

Intelligence Quotient (IQ) scores are often reported to be normally distributed with μ=100.0 and σ=15.0. A random sample of 59 people is taken. Step 1 of 2 : What is the probability of a random person on the street having an IQ score of less than 98 ? Round your answer to 4 decimal places, if necessary.
Using the normal distribution, it is found that there is a 0.4483 = 44.83% probability of a random person on the street having an IQ score of less than 98.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem, the mean and the standard deviation are, respectively, given by [tex]\mu = 100[/tex] and [tex]\sigma = 15[/tex].
The probability of a random person on the street having an IQ score of less than 98 is the p-value of Z when X = 98, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{98 - 100}{15}[/tex]
[tex]Z = -0.13[/tex]
[tex]Z = -0.13[/tex] has a p-value of 0.4483.
0.4483 = 44.83% probability of a random person on the street having an IQ score of less than 98.

4 A game is being watched by 60 adults and some
children. If there are 20 more adults than children,
how many children are watching the game?
Lo Children
Answer:
20 children.
Step-by-step explanation:
We can solve this using an equation or simple mental math:
The equation: x=children x+20=adults
x + (x+20) = 60
2x + 20 = 60
2x = 40
x = 20
Mental Math: 40 plus 20 is 60 and 40 is 20 more than 20 so there are 40 adults and 20 children.

(-8+4i)(1 - i)
Which of the following is equivalent to the complex number shown above?
Note: i = -1
Answer:
-4 + 12i
Step-by-step explanation:
(-8 + 4i) (1 − i)
Distribute using FOIL.
(-8)(1) + (-8)(-i) + (4i)(1) + (4i)(-i)
-8 + 8i + 4i − 4i²
-8 + 12i + 4
-4 + 12i
The product of two complex numbers (-8+4i) and (1 - i) is - 4(1 + i).
What is a complex number?"A complex number is a number of the form a + bi, where 'a' and 'b' are real numbers. Here, i = √(- 1)."
Given, (- 8 + 4i)(1 - i)
= (- 8 + 4i - 8i - 4i²)
= [- 8 - 4i - 4(- 1)]
= (- 8 - 4i + 4)
= (- 4 - 4i)
= - 4(1 + i)

(a) is the college correct?
Show why you think this.
Answer:
yes, (I think)
because 27 more students left this year with a pass and last year the percentage would of been lower I don't know
The college is incorrect, it is 28.125%
What is percentage?Percentage is defined as ratio expressed as a fraction of 100.
No. of students in college in last year = 123 -27 = 96
The number of students leaving college ratio = (27/96)×100%
⇒0.28125×100%
⇒28.125%
