Answer:

$\huge\boxed{\sf e =21}$

Step-by-step explanation:

<u>Given equation:</u>

$\displaystyle \frac{e}{3} = 7\\\\Multiply \ both \ sides \ by \ 3\\\\e = 7 \times 3\\\\e = 21\\\\\rule[225]{224}{2}$

Hope this helped!

Ainat [17]

Answer:

One of the assumptions we sometimes need to make when performing statistical inferences is that the response variable in the population has a Normal distribution. Is it possible to check that this assumption is satisfied?

Statement A is correct

Step-by-step explanation:

When performing statistical inferences, one of the assumptions often made is that the response variable in the population has a normal distribution.

Since we do not have the whole population, the above assumption cannot put to a check.

However, the t distribution is robust to modest departures from normality, thus it can be used, if there are no major outliers in the plot of the data.

Therefore, statement A is correct.

Identify the x- and y- intercepts of this equation. 5 − 4 = 20

Alinara [238K]

T he x and y intercepts of the equation: $5x-4y=20$ are : y-intercept is (0,-5) and x-intercept is (4,0)

So, Option D is correct.

Step-by-step explanation:

we need to identify the x and y intercepts of the equation: $5x-4y=20$

Finding x-intercept

For finding x-intercept put y=0

We are given the equation:

$5x-4y=20$

Solving:

$5x-4y=20\\5x-4(0)=20\\5x=20\\x=\frac{20}{5}\\x=4$

So, x-intercept is (4,0)

Finding y-intercept

For finding y-intercept put x=0

We are given the equation:

$5x-4y=20$

Solving:

$5x-4y=20\\5(0)-4y=20\\-4y=20\\y=\frac{20}{-4}\\y=-5$

So, y-intercept is (0,-5)

the x and y intercepts of the equation: $5x-4y=20$ are :y-intercept is (0,-5) and x-intercept is (4,0)

So, Option D is correct.

Divide £144 in the ratio 11:7

cluponka [151]

Answer:

88:56 = 11:7 pounds.

Step-by-step explanation:

Drop the pound sign. I live in Canada and I can't make that symbol. I'll add something at the end. We just want to divide 144 into a ratio of of 11:7

Step One

Add the two ratios together 11 + 7 = 18

Now set up a ratio to solve for 11 parts out of 18

11:18 = x:144 Proportion

11 / 18 = x / 144 Equation: Cross mulitiply

11*144 = 18x Combine the left side

1584 = 18x Divide by 18

1584 / 18 = x

88 = x

That is the larger amount (11 is larger than 7)

Find the smaller amount

144 - 88 = 56

The two amounts are in the ratio of 11:7

88:56 = 11:7
