Step-by-step explanation:

2(4x - 2) = 8(x - 7)

8x - 4 = 8x - 56

0x = -52

no solution

Answer:

2(4x-2) = 8(x-7)

Distribute on both sides

2(4x)-2(2) = 8(x)-(7)(8)

Simplify

8x - 4 = 8x - 56

Subtract 8x from both sides to balance the equation.

-4 = -56

This is not equal.

Therefore the answer is no solution

Answer:

The answer is pi and the estimate is 3.14

Step-by-step explanation:

Just took the test for plato and Edmentum users only

The estimated value of the expression is π which is approximately equal to the number 3.14.

Simplification is to make something easier to do or understand and to make something less complicated.

The expression is given below.

[tex]\Rightarrow \dfrac{5\sqrt2 \pi - 4\sqrt2 \pi}{\sqrt2}[/tex]

Taking √2and π common, then we have

[tex]\rightarrow \dfrac{(5 - 4)\sqrt2 \pi}{\sqrt2}\\\\\\\rightarrow \dfrac{\sqrt2 \pi}{\sqrt2}\\\\\\\rightarrow \pi \approx 3.14[/tex]

The value of the expression is 3.14.

Answer:

B. f (x) = 2x + 2.5

Step-by-step explanation:

Linear function:

A linear function has the following format:

[tex]y = mx + b[/tex]

In which m is the value that y changes by when x increases by 1, and b is the flat fee.

A bowling alley has a one-time charge of $2.50 to rent a pair of shoes and a charge of $2.00 for each game bowled.

This means that [tex]m = 2, b = 2.50[/tex]

So

[tex]f(x) = 2x + 2.5[/tex]

From this question, we can write

Let n be the number.

9n=3n+30

6n=30

n=5

We find that the number is 30.

Hi there!

it would be 10.. if your asking for what multiply by 9 and 3 more than the number.

1.Find common multiply:

[tex]9,18,27,36,45,54,63,72,81,90,99[/tex]

[tex]30,60,90,120[/tex]

2.Find what nine can multiply to and 30 can also:

[tex]=90[/tex]

3.Divide two terms:

Step-by-step explanation:

Answer:

the probability of a Type II error if in fact the mean waiting time u, is 9.8 minutes is 0.1251

Option A) is the correct answer.

Step-by-step explanation:

Given the data in the question;

we know that a type 11 error occur when a null hypothesis is false and we fail to reject it.

as in it in the question;

obtained mean is 9.8 which is obviously not equal to 8.3

But still we fail to reject the null hypothesis says mean is 8.3

Hence we have to find the probability of type 11 error

given that; it is right tailed and o.5, it corresponds to 1.645

so

z is equal to 1.645

z = (x-μ)/[tex]\frac{S}{\sqrt{n} }[/tex]

where our standard deviation s = 3.8

sample size n = 50

mean μ = 8.3

we substitute

1.645 = (x - 8.3)/[tex]\frac{3.8}{\sqrt{50} }[/tex]

1.645 = (x - 8.3) / 0.5374

0.884023 = x - 8.3

x = 0.884023 + 8.3

x = 9.18402

so, by general rule we will fail to reject the null hypothesis when we will get the z value less than 1.645

As we reject the null hypothesis for right tailed test when the obtained test statistics is greater than the critical value

so, we will fail to reject the null hypothesis as long as we get the sample mean less than 9.18402

Now, for mean 9.8 and standard deviation 3.8 and sample size 50

Z =  (9.18402 - 9.8)/[tex]\frac{3.8}{\sqrt{50} }[/tex]

Z = -0.61598 / 0.5374

Z = - 1.1462 ≈ - 1.15

from the z-score table;

P(z<-1.15) = 0.1251

Therefore, the probability of a Type II error if in fact the mean waiting time u, is 9.8 minutes is 0.1251

Option A) is the correct answer.

Answer:

m = 7

Step-by-step explanation:

1.2m = 8.4

m is being multiplied by 1.2

to get m alone, we do the inverse operation to multiplication which is division.

Divide both sides by 1.2

1.2m/1.2 = 8.4/1.2

m = 7

Answer:

m=7

Step-by-step explanation:

8.4/1.2=7

Answer:

7

Step-by-step explanation:

First multiply 6 by u and 7 to get 6u+7

next add  -8u + 6u and get -2u

then subtract 42 from both sides of the equation (28-42)

finally divide -2u from both sides of the equation and get 7

Answer:

Step-by-step explanation:

height = 14tan(24°)

area = 0.5(base)(height)

Find the angle that triples the height.

tanθ = 3×14tan(24°)

θ = arctan(3×14tan(24°)) ≅ 53.2°

The base angle will be 53.3 degrees when the area gets treble.

A triangle with two sides of equal length is an isosceles triangle.

The angles that have the base as one of their sides are called base angles.

[tex]Area = \frac{1}{2} bh[/tex]

Where,

b is the base of the triangle

h is the height of the triangle

According to the given question

We have,

Base angle of the isosceles triangle is 24 degrees.

Base of the isosceles triangle is 28 cm.

In triangle ABC

We have

BC = 28cm, BD = 14cm, AD = h and ∠ABD = 24 degrees

Now, in right angle triangle ABD

[tex]tan24 = \frac{h}{14}[/tex]

⇒ tan24 × 14 = h

Therefore,

Area of triangle ABC = [tex]\frac{1}{2}[/tex] × 28 × 14 × tan 24

Area of triangle ABC = 196tan24

Therefore, the base angles of an new  isosceles triangle when the area get treble is given but with the same base  by

Area of new isosceles  = 3× area of triangle ABC

⇒ [tex]\frac{1}{2}[/tex]× 28 × tanθ × 14 = 3×196tan24

⇒tanθ =  3 × 0.4452

⇒ tanθ = 1.3356

⇒ θ = [tex]tan^{-1}(1.34)[/tex]

⇒ θ = 53.3 degrees

Hence, the base angle will be 53.3 degrees when the area gets treble.
