Answer:

The new value after an increase

of £258 by 43 will be: 368.94

Step-by-step explanation:

As we have to increase £258 by 43 using the multiplier method.

Let 'n' represent the new value after the increase of £258 by 43 using the multiplier method.

Using the formula

n = 258 + percentage increase

   =258+\left(43\%\:258\right)

   =258\:+\:43\%\:\times 258

Factoring out 258

    =\left(1\:+\:43\%\right)\:\times \:258

as 1 = 100 / 100 = 100%

so

   =\left(100\%\:+\:43\%\right)\:\times \:258

   =143\%\:\times \:258

    =\frac{143}{100}\times 258

    =\:\frac{143\times 258\:\:}{100}

    =\:\frac{36,894\:\:}{100}

    =368.94

Therefore, the new value after an increase

of £258 by 43 will be: 368.94

How do I answer this question
soldi70 [24.7K]

The answer is C. 2.

This is because the part that is inside of the parentheses is equal to 4. Multiplying the fractions in the numerator is equal to 4^\frac{3}{2}.

\frac{4^\frac{3}{2}}{4^\frac{1}{2}}=4., using the exponential rule 3/2-1/2=2/2 or 1. 4^1=4.

Now, we reduced the fraction, so all that is left is (4)^\frac{1}{2}. This is equal to 2.

So your answer is 2.

I hope this helps :)

The data shows the speed, in miles per hour, of motorists on a stretch of road.
melomori [17]

Answer:

i. 18 miles per hour is an outlier

ii. the outlier decreases the mean speed

Step-by-step explanation:

An outlier in a given data is one of the values that is far greater or lesser compared to others. It affect the mean and standard deviation of a given data significantly.

From the given data, 18 is far too small compared to other values. This is certainly an outlier. This would affect the mean speed by decreasing the value.

An interquartile range is a measure of differences among data by dividing a set of given data into quartile. Increasing the value of the outlier would increase the interquartile range.

Jenn equally shares 40 jellybeans with some friends. Is the number that each friends gets greater than 40 or less than 40? Expla
blagie [28]
I would say that it would be less than. The question says Jenn shared a total of 40 jellybeans equally and to share with others, Jenn would have to divide the jellybeans among her friends. Since she is dividing the jellybeans, the amount each friend gets would be less than the total. Therefore it would be less than 40.
