Last year 123 students left a college with a pass in English.
This year 27 more students than last year left the college with a pass in English.
The college says
'The number of students leaving college with a pass in English has increased by 24% from last year!
(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%
The college says,
'The number of students leaving college with a pass in English has increased by 24% from last year
Hence, The college is incorrect, it is 28.125%

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.

if the circumfrence if a circular sheet is 154 then find the radius and area.
take π as 22/7
Answer:
1886.5
Step-by-step explanation:
2πr=154
2*22/7*r=154
44/7r=154
44r=1078
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%

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)

Answer: I think the answer is 60 like the inequality
Step-by-step explanation:
Why? Well basically I did 70 - inequality and got 2 and when I subtracted those numbers it gave me 3 and then I added 3 + 2 and got 5 and then when I did 5 + 3 + 2 I got 80 and then I said thats to much so I divided 80 by 5 and got 33. and I thought 33 was to little so I added an extra 20 and got 60
