Answer:

6w + 2a = 28

Step-by-step explanation:

the expression given, 6w + 2a, contains no variable h, so it's best to just ignore that h = 5.

first, plug in the values for w and a. you can do this in whatever order you want, but i'll start with w for this example.

plug in 4 for w.

6w + 2a

6(4) + 2a

now plug in 2 for a.

6(4) + 2a

6(4) + 2(2)

after plugging in the values, your expression is 6(4) + 2(2).

all that's left is to simplify. again, this can be done in whatever order you prefer, but i'm going to start with 6(4).

6(4) + 2(2)

24 + 2(2)

continue simplifying by multiplying 2(2).

24 + 2(2)

24 + 4

now add 24 + 4.

24 + 4 = 28

so, when w = 4 and a = 2, 6w + 2a = 28.

you can check the answer by plugging those values for a and w back into the completed equation.

6w + 2a = 28

6(4) + 2(2) = 28

24 + 4 = 28

28 = 28

since both sides of the equation are equal, that means that your answer of 28 is correct! :)

i hope this helps! have a great day <3

Step-by-step explanation:

When you move v's tail to u's head, you see that the vectors align up.

The graph shows (u + v) for the given vectors u and v will be Graph A.

A vector is an object that has both a magnitude and a direction. Magnitude defines the size of the vector. It is represented by a line with an arrow, where the length of the line is the magnitude of the vector and the arrow shows the direction.

We have,

Four graphs and we have to tell which is the correct graph for (u + v).

So,

To add two vectors, add the corresponding components.

i.e. The sum of u and v  vector = ( u₁ + v₁, u₂ + v₂)

i.e.

Let u = (u₁, u₂)  and

v = (v₁, v₂)

Now,

(u + v) = ( u₁ + v₁, u₂ + v₂)

So,

From Graph A,

We have,

u = (1, 4) and v = (2, -2)

i.e.

u₁ = 1,

u₂ = 4,

v₁ = 2,

v₂ = -2

So,

Using the addition method of vector,

i.e.

(u + v) = ( u₁ + v₁, u₂ + v₂)

Substituting values,

(u + v) = [( 1 + 2), (4 + (-2))]

We get,

(u + v) = (3, 2)

So,

The graph A represents the correct points of (u +v).

Hence, we can say that the graph shows (u + v) for the given vectors u and v will be Graph A.

Answer:

The 85% confidence interval for the population proportion that claim to always buckle up is (0.7877, 0.8441).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

They randomly survey 391 drivers and find that 319 claim to always buckle up.

This means that [tex]n = 391, \pi = \frac{319}{391} = 0.8159[/tex]

85% confidence level

So [tex]\alpha = 0.15[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.15}{2} = 0.925[/tex], so [tex]Z = 1.44[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.8159 - 1.44\sqrt{\frac{0.8159*0.1841}{391}} = 0.7877[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.8159 + 1.44\sqrt{\frac{0.8159*0.1841}{391}} = 0.8441[/tex]

The 85% confidence interval for the population proportion that claim to always buckle up is (0.7877, 0.8441).

Answer:

The side on triangle PQR that corresponds to side LN in triangle MNL is side QR.

Step-by-step explanation:

Triangle PQR is a dilated version of triangle LMN, specifically a dilation of 2, since LN = 12, the corresponding side to it on triangle PQR is side QR because it is twice as big as side LN, which is the dilation value for converting triangle LMN to triangle PQR.

The side of triangle PQR corresponds to side LN in triangle MNL will be QR.

Similar triangle are those which have two pairs of interior corresponding angles are equal or two pairs of corresponding sides are in proportion.

We have,

Two triangles as shown in the given figure,

Now,

Using triangle similarity rule,

i.e.

Sides are in equal proportion,

i.e.

[tex]\frac{LM}{PR} =\frac{MN}{PQ} =\frac{LN}{QR}[/tex]

So,

Put values of sides ,

[tex]\frac{14}{28} =\frac{10}{20} =\frac{12}{24}[/tex]

i.e.

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

So,

All sides in proportion according to the question,

Now,

The side which is in proportion to side LN is QR.

Hence, we can say that the side of triangle PQR corresponds to side LN in triangle MNL will be QR.

Step-by-step explanation:

Answer:

26 = -28 - 12

Step-by-step explanation:

1. 12 x 1 - 12 x 3x

2. 8x - 36

Answer:

x = 1

Step-by-step explanation:

6x + 26 = 8x - 12(1 - 3x)

6x + 26 = 8x - 12 + 36x

6x + 26 = -12 + 44x

-6 + 6x + 26 = -12 + 44x - 6

26 = -12 + 38x

12 + 26 = -12 + 12 + 38x

38 = 38x

38/38 = 38x/38

Answer:

Test statistic | t| = |-2.0607| = 2.0607

Step-by-step explanation:

Step(i):-

Given that the mean of the Population = 6.0 parts / million

The mean of sample x⁻ = 5.6ppm

The variance of the sample = 0.49

The standard deviation of the sample (s) = √0.49 = 0.7

Step(ii):-

Test statistic

             [tex]t = \frac{x^{-} - mean}{\frac{S}{\sqrt{n} } }[/tex]

             [tex]t = \frac{5.6 - 6.0}{\frac{0.7}{\sqrt{13} } }[/tex]

            t = -2.0607

Final answer:-

Test statistic | t| = |-2.0607| = 2.0607

Step-by-step explanation:

I say 14 inches because width for the board at the restaurant is 36 (3×12) and the length is (3×7) so if the width for the board at home is 24 ( 2×12) then the length must be 14 ( 2×7). See what I did?

His home cutting board will be 14 inches long.

Since Emeril is building a cutting board for his home kitchen, and he wants it to be similar in size to the cutting board at gis restaurant, which is 36 inches wide by 21 inches long, and he has enough space on his home counter for a board that is 24 inches wide, to determine how long will his home cutting board be the following cross multiplication calculation must be performed:
