Last year, Rebecca's car insurance cost her £2043. This year it only cost her £1675.26 By what percentage has Rebecca's car insurance been reduced?

Answers

Answer:

Step-by-step explanation:

Rebecca's car insurance been reduced by 18%

What is percentage?

A percentage is a number that tells us how much out of 100 and can also be written as a decimal or a fraction.

Given that, Last year, Rebecca's car insurance cost her £2043. This year it only cost her £1675.26.

Percentage decrease = (Final value - initial value) / initial value × 100

Final value = £1675.26

Initial value = £2043

Percentage decrease = (2043 - 1675.26) / 2043 × 100

= 367.74 / 2043 × 100

= 0.18 × 100

= 18 %

Hence, Rebecca's car insurance been reduced by 18%

Identify the number that does not belong with the other three. Explain your reasoning.

Answers

Answer:

To identify which integer does not belong with the rest, we must first evaluate each.

Step-by-step explanation:

[25.6...] is already evaluated. Therefore, let's move on to Integer b: [tex]\sqrt{x}[/tex], where is x is 48.

48 = 2 * 24--> 2 * 12--> 2 * 6--> 2 * 3√48 = [tex]\sqrt{2}[/tex] * 2 * 2 * 2 * 3We have 1 perfect sqaure: [tex]\sqrt{2}[/tex] * 2When we multiply, we receive 2.Therefore, 2 * [tex]\sqrt{2 * 3}[/tex]

When -51/2 is relatively prime, we receive -25 1/2

Finally, the last integer is already simplified.

Based on these results, you may determine the number that does not belong with the other three, whether than is through means of irrationability, value, absolte value, or whatever other means you decide.

Find the area of the shaded polygon.

Answer:

Step-by-step explain to solve for the maximum area, the first derivative should be solved and equate it to zero, then solve for x.

A = 37x - x^2

dA / dx = 37 - 2x

equate dA / dx = 0

0 = 37 - 2x

2x = 37

x = 37 / 2

x = 18.5 ft

so the maximum area is

A = 37x - x^2

A = 37( 18.5) - 18.5^2

A = 342.25 sq ft

so the answer is letter B

The distribution of tips given by customers who buy one cup of coffee is bimodal with a mean of $0.29 and a standard deviation of $0.1164. If a random sample of 50 tips from customers who buy one cup of coffee is selected, is it appropriate to calculate the probability of a sample mean being more than $0.32 using an approximately Normal model?

Yes, the population of all people who buy one cup of coffee is extremely large, so the shape of the sampling distribution of x is not a concern, and P(x> 32) = 0.0372.

Yes, since the sample size 50 is large enough, the sampling distribution for x would be approximately Normal, and P(x>32) = 0.0372.

Yes, since the sample size 50 is large enough, the sampling distribution for x would be approximately Normal, and P(x> 32) = 0.3983.

No, it is not appropriate to estimate the probability using an approximately Normal model because the population is not Normal, and the sample size is not reasonably large.

HELI KADAKIA to study ofc

The graph of (x + 5)² + (y – 10)² < 169. The circle with centre at (5, –10), shading inside the circle. The correct option is B.

What is a circle?

A circle is a two-dimensional geometry on the plane having a centre point and the circular line is drawn equidistant from the centre point. A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

The given equation of the graph is f(x + 5)² + (y – 10)² < 169. When we plot the equation we get the circle having an inside shaded part. The coordinates of the circle are (5,-10).

Therefore, the graph of (x + 5)² + (y – 10)² < 169. The circle with centre at (5, –10), shading inside the circle. The correct option is B.
