Decrease £14120 by 4% Give your answer rounded to 2 DP.
Answer:
(14120/100)*96 = £13,555.20
Step-by-step explanation:
Answer:
£13,555.20
Step-by-step explanation:
14120*4=56480
56480+14120=70,600
then 70,600+20
on a cauculaiter it will give you 70,620 but it is 70,600.20
then 14,1000.50-1,555.30=13,55.20
hope it is helpfull

Answer:
root 40 or 2 root 10
Step-by-step explanation:
You have to use the formula...
a^2 + b^2 = c^2
So...
2^2 + 6^2 = c^2
4 + 36 = 40
Which means...
Answer is root 40 or simplified... 2 root 10

The ground temperature at airport is 12 degrees. The temperature decreases by 5.2 degrees for every mile above ground. What would be temperature outside plane located at 3 miles above the airport
Answer:
The outside plane located at 3 miles above the airport is of -3.6 degrees.
Step-by-step explanation:
The ground temperature at airport is 12 degrees. The temperature decreases by 5.2 degrees for every mile above ground.
This means that the temperature in n miles above ground is given by:
[tex]T(n) = 12 - 5.2n[/tex]
What would be temperature outside plane located at 3 miles above the airport
This is T(3). So
[tex]T(3) = 12 - 5.2*3 = 12 - 15.6 = -3.6[/tex]
The outside plane located at 3 miles above the airport is of -3.6 degrees.
A self-serve frozen yogurt store sells servings up to 12 ounces. It charges $0.50 per ounce for a serving between 0 and 8 ounces, and $4 for any serving greater than 8 ounces and up to 12 ounces.
Answer:The answer is graph B.
Step-by-step explanation: It keeps going up at 0.50 because that is the price PER OUNCE for a serving between 0-8 ounces. The line on the graph is going straight at 4 because that is the price for ANY SERVING over 8 ounces/up to 12 ounces.

A car manufacturer produced 5.000 cars for a limited edition model Dealers sold all of these cars at mean price of $36,000 with a standard deviation of $3,000. Suppose we were to take random samples of 9 of these cars and calculate the sample mean price for each sample. Calculate the mean and standard deviation of the sampling distribution of .
Answer: Mean = $36,000 and standard deviation = $1000.
Step-by-step explanation:
The mean and the standard deviation of the sampling distribution of the sample mean:
[tex]Mean=\mu\\\\Standard\ deviation = \dfrac{\sigma}{\sqrt{n}}[/tex] , where n =sample size.
Here, we are given
[tex]\mu=\$36000,\ \ \sigma=\$3,000[/tex]
n= 9
Then, the mean and the standard deviation of the sampling distribution of the sample mean:
[tex]Mean=\$36000,\ \ Standard\ deviation=\dfrac{3000}{\sqrt{9}}=\dfrac{3000}{3}=\$1000[/tex]
Hence, Mean = $36,000 and standard deviation = $1000.

uppose you have purchased a filling machine for candy bags that is supposed to fill each bag with 16 oz of candy. Assume that the weights of filled bags are approximately normally distributed. A random sample of 10 bags yields the following data (in oz): 15.87, 16.02, 15.78, 15.83, 15.69, 15.81, 16.04, 15.81, 15.92, 16.10 On the basis of this data, can you conclude that the mean fill weight is actually less than 16 oz? Let LaTeX: \alpha=5\%α = 5 %. What would be the appropriate null and alternative hypothesis?
Answer:
Null, H0: μ ≥ 16
Alternative ; H1: μ < 16
reject H0
Step-by-step explanation:
Null, H0: μ ≥ 16
Alternative ; H1: μ < 16
To compute the test statistic :
We need the sample mean and sample standard deviation :
15.87, 16.02, 15.78, 15.83, 15.69, 15.81, 16.04, 15.81, 15.92, 16.10
Using calculator :
Sample mean, m = 15.887
Standard deviation = 0.13
Test statistic :
(m - μ) / s/sqrt(n)
(15.887 - 16) / 0.13/sqrt(10)
-0.113 / 0.0411096
= - 2.749
Tcritical at 95%
Tn-1, 0.025
T10,0.025 = 2.262
Since the test statistic value is less than the critical value, reject H0
. sells t-shirts for $2 and shorts for $4 in April the total sales were 600.00 people bought four times as many t-shirts as shorts how many t-shirts and shorts did they sell?
Answer:
200 t-shirts and 50 shorts
Step-by-step explanation:
t= t-shirts
s = shorts
600 = 2t + 4s
t = 4s
600 = 2(4s) + 4s
600 = 8s + 4s ––––> 600 = 12s
s = 50
t = 4(50) –––––> t = 200
check:
600 = 2(200) + 4(50)
600 = 400 + 200
600 = 600

For a two-day rental at the surf shop, it cost $55 to rent a surf board and $70 to rent a paddle board. On a certain weekend, the surf shop rented 51 total surf boards and paddle boards and made $3300. How many paddle boards were rented?
Answer:
7 paddleboards
Step-by-step explanation:
In order to solve this, you have to find the total amount that they earned by renting surfboards.
To find this you multiply 55 x 51 =2,805.
Then you use this factor and subtract it from the total amount they earned.
$3,300 - $2,805 = $495.
This shows us that they earned a total of $495 from renting out paddle boards. To find out how many paddle boards were rented out you have to divide $495 by $70 which is how much they charge to rent paddle boards.
495/70 = 7
In conclusion, they rented out 7 paddle boards.

n times 5 is equal to 24
word in equation and solve for variable
Step-by-step explanation: Remember that "times" mean multiply.
So reading the problem from left to right, we have n times 5,
that's n multiplied by 5 or 5n, is means equals, 24.
So we have 5n = 24.
We want to solve our equation for n so we want to get
n by itself on the left side of the equation.
Since n is being multiplied by 5, we need to divide both sides
of the equation by 5 and we have n = 24/5.
Don't be nervous to check your answer back in
the original equation even if it is a fraction.
4) The length of a rectangle is 7 inches more than the width. The perimeter of the rectangle
is 178 inches. Find the width of the rectangle.
Answer:
41 inches
please mark brainliest
Step-by-step explanation:
l= 7+w
perimeter = 2(l+w) =2(7+w +w)= 2(7+2w)= 14+ 4w
178= 14+4w
4w =178-14= 164
w= 164/4 = 41 inches
