2) Mateo scored 99 out 150 on an exam. What’s his score as a percentage?
Answer:
You divide the smaller number by the bigger, or the received points out of the total, so you would divide 99 by 150 giving you 66%
Answer : 66%
Explanation : 33 ÷ 50 Or 99 ÷ 150
Tasha earns $75,000 per year. Her payroll deductions are 28% of her gross income. She saves 5% of her net
income each month in case of an emergency. How much will she budget for her emergency savings for the month
of March?
O $3,750
$312.50
O $87.50
O $225.00
Answer:
87.50
Step-by-step explanation:
75,000 x 28% ÷ 12
She will budget $225 for her emergency savings for the month of March
How to determine the amount saved for emergency?We have:
Gross = $75,000 per year.
Payroll deductions = 28%
So, the net pay is:
Net = (1 - 28%) * $75,000
Evaluate
Net = $54000
The net income per month is:
Monthly = $54000/12
Evaluate
Monthly = $4500
5% of her net income goes to emergency.
So, we have:
Emergency = 5% * $4500
Evaluate
Emergency = $225
Hence, she will budget $225 for her emergency savings for the month of March

You know that S times A is the digit N. Then, A squared plus whatever the first digit of the2 digit number XN is MA.
A cannot be five because if you were to do 5 times 5 it would be 25. A squared is 25 and the last digit is already A so added on to anything else the equation would be false. So the only considerable value for S would be one, but then A times S would be 5, but N is not A. I hope you get what I mean.
A cannot be 6 for the same reason (just change the 5 to six on my last pragraph).
If A were 7 then you'd have to find something to add to 49 to make it end in 7, which means adding 6. 7 times 9 is 63, so S could be 9. 79 times 7 is 573. That is the answer. A = 7, S = 9, M = 5, N = 3.
As for NINE - FOUR = FIVE, E - R is E so R must be 0.The only one digit number a number can be subtracted by to get itself is 0.
Now, N - U = V, or 1N - U = V
Let's say N is 3 and U is 6. V would be 7.
We've just took one from I. I - 1 - O = I. 1+O must be 10 or 0, but O must be positive, so O = 9. Let's say I is 5.
We just borrowed one form N. N-1 - F = F. N - 1 = 2 times F.
But we know that N is 3. 2 = 2 times F. F is 1.
Let's just make E = 8
My final answer is 3538 - 1960 = 1578
There are MANY other answers though.
N = 3, I = 5, E = 8, O = 9, U = 6, R = 0, V = 7.
Two joggers set out at the same time from their homes 21 miles apart. They agree to meet at a point somewhere in

The two joggers who are 21 miles apart travel at a speed 8 mph and 6 mph respectively and would meet after one and half hours.
What is an equation?An equation is an expression used to show the relationship between two or more variables and numbers.
Let a represent the speed of the faster jogger and represent the speed of the other jogger. Hence:
a = b + 2 (1)
Also:
In one and half hour (1.5 h):
a = d₁/1.5
d₁ = 1.5a
b = d₂/1.5
d₂ = 1.5b
d₁+ d₂ = 21
1.5a + 1.5b = 21 (2)

a = 8, b = 6

Write a equation: Two thirds of a number decreased by the product of a number and two, squared, is 43 (PLEASE ANSWER ASAP )
We can transform the mathematical sentence into the equation:
(2/3)*x - (2*y)^2 = 43
How to write the equation?
Here we have the sentence:
" Two thirds of a number decreased by the product of a number and two, squared, is 43"
First, we can define x as "the number"
Then:
" Two thirds of a number..." is:
(2/3)*x
Now we add the next part:
"... decreased by the product of a number and two, squared, is 43"
Assuming that this is another number, let's call it y, we have:
(2/3)*x - (2*y)^2 = 43

26
%.
Complete parts a) through c) below.
a) What would the managers expect the shape of the sampling distribution for the sample proportion to be?
Skewed to the left
Unimodal and symmetric
Skewed to the right
Nonsymmetric
b) What would be the mean of this sampling distribution?
(Round to two decimal places as needed.)
c) What would be the standard deviation of the samplingdistribution?
(Round to three decimal places as need
Answer: a) Unimodal and symmetric
b) 0.26
c) 0.038
Step-by-step explanation:
Given: Sample size of investors (n)= 131
True proportion of smartphone users(p) =26%
a) Since sampling distribution for the sample proportion is approximately normal when n is larger.
Normal distribution is Unimodal and symmetric.
So correct option : Unimodal and symmetric
b) mean of this sampling distribution = p = 0.26
c) standard deviation of the samplingdistribution = [tex]\sqrt{\dfrac{p(1-p)}{n}}=\sqrt{\dfrac{0.26\times (1-0.26)}{131}}=\sqrt{0.00146870229008}[/tex]

Total = ₹4500 + ₹540
= ₹5040
Answer:
Rs. 5040
Step-by-step explanation:
Price of cellphone=Rs. 4500
Gst additionally=12%
=12% of Rs. 4500
12/100 * 4500

The original price of a T-Shirt is $15. The T-Shirt is on sale for 35% off. What is the sale price?
Answer:
9.75$
Step-by-step explanation:
Answer:
9.75$
Step-by-step explanation:
The original price of the shirt is $15, and it's on sale for 35% off. What is the item's sale price?
First, convert the 35% to a real mathematical number. For percents, this is always done by dividing the 35% by 100%, or 35% / 100% = 0.350.
Second, find out what 35% of $15 is. This is the amount of the sale discount. This is always found by multiplying 0.350 by the item's cost $15, like this:
0.350 x $15 = $ 5.25.
So for this sale, you'll save $ 5.25 on this item.
This means, the cost of the item to you is
$15 - $ 5.25 = $ 9.75.
