Please help me this is due today

Serjik [45]

Answer:

1. 15 (A)

2. 12 (G)

Step-by-step explanation:

1. We can make an equation out of this...

3x+3=48

x is the age of Geoff which is what we are trying to find out

We have to add 3 to both sides of the equation

3x+3=48

-3 -3

________

we end up with 3x=45

we then have to divide 3 by both sides because its the opposite of

multipling

3x=45

_____

we get x=15

2. We can write a problem statement

(2 x 9)-6=?

multiply 2 and 9 FIRST

18-6=?

your answer is 12

Your Welcome! Have a great rest of your day! :)

A sample of 140 Vopstra customers have had their annual phone charge recorded for the previous calendar year. The data were used

taurus [48]

Answer:

Correct option: (a)

Step-by-step explanation:

A confidence interval is an interval estimate of the parameter value.

A (1 - α)% confidence interval implies that the confidence interval has a (1 - α)% probability of consisting the true parameter value.

If 100 such confidence intervals are made then (1 - α) of these intervals would consist the true parameter value.

The 92% confidence interval for the mean annual phone charge of all Vopstra customers is:

$\$470\pm \$65=(\$405, \$535)$

This confidence interval implies that true mean annual phone charge of all Vopstra customers is contained in the interval ($405, $535) with 0.92 probability.

Thus, the correct option is (a).

Which ordered pair is a solution of the equation? Y-4=7(x-6)

deff fn [24]

Answer:

(6,4)

Step-by-step explanation:

The equation is in 'point-slope' form.

$y-y_1=m(x-x_1)\\\rule{150}{0.5}\\(x_1,y_1) \rightarrow \text{a point that's given}\\\\m \rightarrow \text{slope}$

This means we can identify the point that was used in the equation.

$y-\boxed{y_1} =m(x-\boxed{x_1}) | y-\boxed{4}=7(x-\boxed{6})\\\rule{210}{0.5}\\y_1 = 4\\\\x_1 =6\\\rule{210}{0.5}\\(x_1,y_1) \rightarrow \boxed{(6,4)}$

(6,4) would be a solution to the equation given.

Hope this helps.
