Answer: 3

Step-by-step explanation:

In 5 years, Jumoke will be 16. 16 divided by 2 is 8. Amina will be 8 in 5 years. If we subtract 5 from 8, we see that Amina is 3 currently.

Answer:

6 years old

Step-by-step explanation:

Suppose Amina's age is "a" and Jumoke's age is "j". We know that Jumoke is 11 years older than Amina, so we can say: j = a + 11

In 5 years' time, Jumoke will be twice as old as Amina then. In 5 years, Jumoke will be j + 5 years old, and Amina will be a + 5 years old. Since Jumoke will be twice as old then, the equation is: j + 5 = 2 * (a + 5)

We can substitute a + 11 in for j in the second equation:

(a + 11) + 5 = 2 * (a + 5) = 2a + 10

a + 16 = 2a + 10

a = 6

Thus, Amina's present age is 6 years old.

Hope this helps!

What is the vertex of the equation y = -x 2 + 10x - 28?
Roman55 [17]

Answer:

(5,-3)

Step-by-step explanation:

Rewrite the equation in vertex form

y =-(x-5)^2 - 3

You take the value of -5 (that would be your x value) and change it to the opposite sign -> +5

Then you take -3 (that would be your y value) and take it as it is

therefore the answer is (5, -3)

Statistics Question. Use the Desmos graphing calculator to find the least-squares regression line for the dataset in the table:
Soloha48 [4]

Given:

The table of values.

To find:

The least-squares regression line for the data set in the table by using the desmos graphing calculator.

Solution:

The general form of least-squares regression line is:

\hat{y}=mx+b           ...(i)

Where, m is the slope and b is the y-intercept.

By using the desmos graphing calculator, we get

m\approx 2.55,b\approx -6.435

Substitute these values in (i).

\hat{y}=(2.55)x+(-6.435)

\hat{y}=2.55x-6.435

Therefore, the correct option is A.
