Answer: x=26-14

Step-by-step explanation :you need to subtract on both sides so that why it is x=26-14.

Answer:

Since they have different z-scores, they are not earning relatively the same.

Step-by-step explanation:

We use z-scores to solve this question.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this question:

They will be earning relatively the same if they have the same z-score.

Tokyo:

Earns 460, mean 420, standard deviation 20. So [tex]X = 460, \mu = 420, \sigma = 20[/tex]. The z-score is:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{460 - 420}{20}[/tex]

[tex]Z = 2[/tex]

Hamburg:

Earns 3300, mean 3200, standard deviation 57. So [tex]\mu = 3300, \sigma = 3200, \sigma = 57[/tex].

The z-score is:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{3300 - 3200}{57}[/tex]

[tex]Z = 1.75[/tex]

Since they have different z-scores, they are not earning relatively the same.

Answer:

Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities.

For example, "The ratio of wings to beaks in the bird house at the zoo was 2:1, because for every 2 wings there was 1 beak."

"For every vote candidate A received, candidate C received nearly three votes."

Answer:

54.91 i think!!

Step-by-step explanation:

Answer:

Step-by-step explanation:

Use a distributive property.

Isolate the term of y from one side of the equation.

[tex]\Longrightarrow: \sf{A(B+C)=AB+AC}[/tex]

⇒: 4(y+2)=32

First, divide by 4 from both sides.

[tex]\Longrightarrow:\sf{\dfrac{4(y+2)}{4}=\dfrac{32}{4} }[/tex]

Solve.

⇒ 32/4=8

⇒ y+2=8

Subtract by 2 from both sides.

[tex]\Longrightarrow \sf{y+2-2=8-2}[/tex]

Solve.

Subtract the numbers from left to right.

8-2=6

y=6

Answer:

<A must be congruent to <A, <P must be congruent to <P, <Q must be congruent to <S, and <R must be congruent to <R

Step-by-step explanation:

Separate the vectors into their x- and y-components. Let u be the vector on the right and v the vector on the left, so that

u = 4 cos(45°) x + 4 sin(45°) y

v = 2 cos(135°) x + 2 sin(135°) y

where x and y denote the unit vectors in the x and y directions.

Then the sum is

u + v = (4 cos(45°) + 2 cos(135°)) x + (4 sin(45°) + 2 sin(135°)) y

and its magnitude is

||u + v|| = √((4 cos(45°) + 2 cos(135°))² + (4 sin(45°) + 2 sin(135°))²)

… = √(16 cos²(45°) + 16 cos(45°) cos(135°) + 4 cos²(135°) + 16 sin²(45°) + 16 sin(45°) sin(135°) + 4 sin²(135°))

… = √(16 (cos²(45°) + sin²(45°)) + 16 (cos(45°) cos(135°) + sin(45°) sin(135°)) + 4 (cos²(135°) + sin²(135°)))

… = √(16 + 16 cos(135° - 45°) + 4)

… = √(20 + 16 cos(90°))

… = √20 = 2√5

Answer: 2√5

Step-by-step explanation:

Use the Sine Law of triangles: In triangle with sides of length 1,2,3 that are opposite to angles 1,2,3 we have

1/sin1=2/sin2=3/sin3.

Answer:

PZ = 15

Step-by-step explanation:

Similar Triangles

Two triangles are similar if all of their corresponding side lengths are proportional to the same scale factor.

It's given triangles TPR and XPZ are similar, thus we can find the scale factor by comparing two corresponding sides with known lengths.

Sides TR and ZX are corresponding and the proportion of their side lengths is 15/9. The same proportion must be satisfied by the sides TP and XP:

[tex]\displaystyle \frac{15}{9}=\frac{25}{PX}[/tex]

PX and PZ are congruent, thus:

[tex]\displaystyle \frac{15}{9}=\frac{25}{PZ}[/tex]

[tex]\displaystyle PZ=25*\frac{9}{15}[/tex]

Calculating:

PZ = 15

Answer:

The value of y  = 30 when x = 5

Step-by-step explanation:

We know that when 'y' varies directly proportional to 'x', we get the equation

y ∝ x

y = kx

k = y/x

where k is called the 'constant of direct variation'.

We are given

y = 12 when x = 2

so substituting y = 12 and x = 2 in the equation

k = y/x

k = 12/2

k = 6

Thus, the value of k = 6

We have to determine the value of y when x = 5

so substitute x = 5 and k = 6 in the equation

y = kx

y = 6(5)

y = 30

Therefore, the value of y  = 30 when x = 5

Answer:

After 10 weeks, Tara will have taken 50 quizzes.

Step-by-step explanation:

Given that Tara took a total of 45 quizzes during the 9-week course, to determine the number of quizzes she will take after 10 weeks, taking into account that it is a proportional relationship, the following calculation must be performed:

(45/9) x 10 = X

5 x 10 = X

50 = X

So, after 10 weeks, Tara will have taken 50 quizzes.
