Answer:
lower than Amanda: 816 students
Step-by-step explanation:
An equivalent way in which to state this problem is: Find the area under the standard normal curve to the left (below) 940.
Most modern calculators have built in distribution functions.
In this case I entered the single command normalcdf(-1000,940, 850, 100)
and obtained 0.816.
In this particular situation, this means that 0.816(1000 students) scored lower than Amanda: 816 students.
Answer:
Lower than Amanda : 816 students. A student studied for 1 hour and earned a 50% on her test. If she had studied for 2
hours, she would have scored a 100% on her test. Help asap please
You have to double 1 and 50 to get 2 and 100
1:50 = 2:100
1x2=2
50x2=100
So the statement, if she studied for 2 hours, she would have gotten 100%, makes sense
Hope this helps!
A rectangle is 64cm long 40cm wide find is area and perimeter
Answer:
Area= 2560 Perimeter= 208
Step-by-step explanation:
Answer:
64 x 40 = 2,560 <------- your area because multiply the two given lengths.
64 + 64 + 40 + 40 = 208 <---------- your perimeter since opposite sides are parallel which means 2 sides are different. So two of both of the different lengths will be your perimeter.

At cycle and sport, customers can rent bikes, electric scooters, kayaks, canoes or paddleboards by the hour. Ari is renting a bike, meg is renting a electric scooter.
Answer:
Option A, 9b + 10s is correct
Step-by-step explanation:
The complete question is
At cycle and sport customers can rent bikes, electric scooters, kayaks, canoes, or paddleboards by the hour. Ari is renting a bi ke, and meg is renting an electric scooter. Which expression represents the total cost for Ari to rent a bike for b hours and Meg to rent a scooter for s hours (Please answer ASAP) A. 9b + 10s B. 9 + 10 C. (9+b) + (10 + s) D. 9 + 10 x b + s
Solution
The price of renting a bike for one hour is $9
The price of renting a scooter for one hour is $10
Given -
Ari rents a bike for b hours and Meg rents a scooter for s hours
Total cost of renting a bike is 9 * b
Total cost of renting a scooter is 10* s
The total cost of renting both the bike and scooter is
9b + 10s
Hence, option A is correct
Your family spends $30 for tickets to an aquarium and $3 per hour for parking. Write an equation that gives the total cost of your family’s visit to the aquarium as a function of the number of hours that you are there. If your family stays for 8 hours, how much money did your family spend for the visit?
Answer:
$54
Step-by-step explanation:
Total cost = ticket cost + parking cost:
C(x) = $30 + ($3/hr)x
An 8-hour stay would cost:
C(8) = $30 + ($3/hr)(8) = $54

A team of biologists is studying a population of 800 fish they find that 15 out of every 75 fish are more than 30cm long based of this result how many fish in the population are 30 cm or less in length
Answer:
640
Step-by-step explanation:
Since 15 out of every 75 fish are more than 30 cm long, the probability of finding a fish more than 30 cm is P(x > 30) = 15/75 = 1/5.
The probability of finding a fish 30 cm or less is P(x ≤ 30) = 1 - P(x > 30)
= 1 - 1/5
= (5 - 1)/5
= 4/5
Since we have 800 fish and the probability of finding a fish 30 cm or less is P(x ≤ 30) = 4/5, then the number of fish in the population that are 30 cm or less in length are 800 × P(x ≤ 30) = 800 × 4/5
= 160 × 4
= 640
So, 640 fish in the population are 30 cm or less in length
Jesse sent an email to 4 people for a school project. In her email, she requested that each person copy and send the same email to 4 additional people.If everyone continues to send the email as requested, which equation could be used to determine the number of emails, y, that will be sent for a given round, x?
M. y = x^4
P. y = 4^X
R. y = 4x
S. y = 4/X
Answer:
The equation could be used to determine the number of emails, y, that will be sent for a given round, x, is:
P. y = 4^XStep-by-step explanation:
To obtain the equation you must know how many emails will be sent in each case, taking into account that Jesse requested that each person copy and send the same email to 4 additional people, then:
First round: Jesse's emails = 4Second round = 16 = 4*4Third round = 64 = 16*4Fourth round = 256 = 64*4How you can see, each round is the same that to multiply the last sent emails by four, so, with the equation selected in the answer we can obtain these results:
y = 4^XIn the first round:
y = 4^(1)y = 4In the second round:
y = 4^(2)y = 16In the third round:
y = 4^(3)y = 64And, in the fourth round:
y = 4^(4)y = 256By this reason, the equation y = 4^X is the correct answer.
-8 = 1.3m - 2.1?
Pls help
Answer:
m=−4.538462
Step-by-step explanation:
Step 1: Flip the equation.
1.3m−2.1=−8
Step 2: Add 2.1 to both sides.
1.3m−2.1+2.1=−8+2.1
1.3m=−5.9
Step 3: Divide both sides by 1.3.
1.3m
1.3
=
−5.9
1.3
Answer: -4.538
Step-by-step explanation: -8=1.3m-2.1
add 2.1 to both sides to get 1.3m=-5.9
divide both sides by 1.3 to get -5.9/1.3
-4.538
Check
1.3(-4.538)-2.1=-7.999
round it to equal -8

Which statement is the most appropriate comparison of the centers?
It's D. the median for town A, 30, is less than the median for town B, 40.
The median for town A at 30° is less than the median for town B at 40°.
So, option (D) is the correct answer.
What is the median?The median is the "middle" of a sorted list of numbers. To find the median, place the numbers in value order and find the middle number".
For the given diagram,
Town A has temperatures = 20°, 30°, 40°
Town B has temperatures = 30°, 40°, 50°
The median of A = 30°
The median of B = 40°
Hence, From the above values, the median for town A at 30° is less than the median for town B at 40°.
Hence, we can conclude that option (D) is the correct answer.

Which expression is equivalent to 2w? w+w
2w+w
2w-w
w+2
Answer:
It is equivalent to w+w
Step-by-step explanation:
w+w= 2w
Answer:
A w+w
Step-by-step explanation:
because 2w means 2 * w ( 2 times w)
when you multiply 2 time any number, you add that number twice,
exp... 4 times 2 = 4 + 4
therefore 2w is also w+ w
given 2x - 9y - 12 = 0, express 5x - 4y + 7 = 0 in terms of x only
Answer:
[tex]4 \frac{1}{9}x[/tex] + [tex]12\frac{1}{3}[/tex] = 0
Step-by-step explanation:
Based on 2x - 9y - 12 = 0
-9y = 12 - 2x
9y = -12 + 2x
y = [tex]-1\frac{1}{3} + \frac{2}{9} x[/tex]
Therefore...
5x - 4y + 7 = 0
5x - 4([tex]-1\frac{1}{3} + \frac{2}{9} x[/tex]) + 7 = 0
5x + [tex]5\frac{1}{3}[/tex] - [tex]\frac{8}{9} x[/tex] + 7 = 0
[tex]4 \frac{1}{9}x[/tex] + [tex]12\frac{1}{3}[/tex] = 0
