Answer: 0.1359

Step-by-step explanation:

mean = $400

Standard deviation = $50

Since the wages is normally distributed , the first thing is to find the z - score.

z = [tex]\frac{x-mean}{standard deviation}[/tex]

finding the z - value for 300 and 350 , we have

z = [tex]\frac{300-400}{50}[/tex]

z = [tex]\frac{-100}{50}[/tex]

2 = -2

also

z = [tex]\frac{350-400}{50}[/tex]

z = [tex]\frac{-50}{50}[/tex]

z = -1

The next thing is to check the calculated value on z - table.

From z - table :

P (z[tex]\leq[/tex] -2 ) = 0.0228

P ( z [tex]\leq -1[/tex] ) = 0.1587

combining the two

P ( -2[tex]\leq[/tex]z[tex]\leq[/tex]-1 ) = 0.1587 - 0.0228

P ( -2[tex]\leq[/tex]z[tex]\leq[/tex]-1 ) = 0.1359

Therefore , the the probability that a worker

selected at random makes between

$300 and $350 = 0.1359

Step-by-step explanation:

Answer:

[tex]x=3.1950[/tex]

Step-by-step explanation:

Given:

The equation to solve is given as:

[tex]\log_8 12=x-2[/tex]

In order to solve this, we use the base change formula of logarithms.

The base change formula is given as:

[tex]\log_a b=\frac{\log b}{\log a}[/tex]

Therefore, the equation can be rewritten as:

[tex]\frac{\log 12}{\log 8}=x-2[/tex]

Adding 2 on both the sides, we get:

[tex]x=2+\frac{\log 12}{\log 8}[/tex]

Now, we know that, [tex]\log 12=1.07918\ and\ \log 8=0.9031[/tex]

Plug in these values and solve for 'x'. This gives,

[tex]x=2+\frac{1.07918}{0.9031}\\\\x=2+1.19497=3.19497\approx3.1950[/tex]

Therefore, the value of 'x' is 3.1950 rounded to four decimal places.

Answer:x=3.1950 on ed yw

Step-by-step explanation:

Step-by-step explanation:

In given figure,

Base (b) = 11 and Angle = 28°

To find, the value of x = ?

We know that,

[tex]\cos A=\dfrac{b}{h}[/tex]

Where, h is the hypotaneous = x

⇒ [tex]\cos 28=\dfrac{11}{x}[/tex]

⇒ [tex]x=\dfrac{11}{\cos 28}[/tex]

The value of [tex]\cos 28[/tex] = 0.8829

⇒ x = [tex]\dfrac{11}{0.8829}[/tex]

⇒ x = 12.458

⇒ x ≈ 12.5

∴ The value of x ≈ 12.5

Thus, the value of x "option A) 12.5" is required answer.

Step-by-step explanation:

You can probably figure out the rectangle of 16 by 8 so no explaining there. 16×8=128. You know that diameter of the cirkel is equal to y so 8. The diameter of a cirkel is two times its radius. so 8=2r. r=4. The area of a cirkel is calculated by the formula \pi×r^2. Fill in r=4 in \pi×r^2 gives us \pi×4^2=16\pi. You only have half of the cirkel so 16\pi/2=8\pi. 128+8\pi=153.12 which is A.

There are [tex]\frac{5}{12}[/tex] of these components together

Solution:

As a science experiment Mo and Jo want to send their rocket into space

They need 1/4 cup of water and 1/6 cup of a secret component

From given question,

[tex]\text{Cup of water} = \frac{1}{4}\\\\\text{Cup of secret component } = \frac{1}{6}[/tex]

How much is there of these two components together?

So we need to add these together

[tex]\text{Cup of water}+ \text{Cup of secret component } = \frac{1}{4} + \frac{1}{6}\\\\\text{Cup of water}+ \text{Cup of secret component } = \frac{1 \times 6}{4 \times 6} + \frac{1 \times 4}{6 \times 4}\\\\\text{Cup of water}+ \text{Cup of secret component } =\frac{6}{24} + \frac{4}{24}\\\\\text{Cup of water}+ \text{Cup of secret component } = \frac{6+4}{24} = \frac{10}{24} = \frac{5}{12}[/tex]

Thus there are [tex]\frac{5}{12}[/tex] of these components together

Final answer:

The egg will take approximately 3.35 seconds to reach the ground.

Explanation:

To solve this problem, we can use the equation [tex]y = yo + vot + 0.5at^2[/tex] position, yo is the initial position, vo is the initial velocity, a is the acceleration, and t is the time.

In this case, yo = 90 ft, vo = 0 ft/s, a = -16 [tex]ft/s^2[/tex]y = 0 ft (since the egg reaches the ground). Plugging these values into the equation, we get 0 = 90 + (0)(t) + 0.5(-16)t^2.

Simplifying the equation, we have [tex]0 = 90 - 8t^2[/tex], we get[tex]8t^2 = 90[/tex] both sides by 8, we get [tex]t^2 = 11.25[/tex]e square root of both sides, we find that t ≈ 3.35 seconds.

Answer:

It takes May 6 minutes and 24 seconds to run 4 laps and 1 minute and 36 seconds per lap

Statement and question:

May runs around a 400-meter track at a constant speed of 250 meters per minute. How many minutes does it take May to complete 4 laps of the track?

Source:

Previous question that can be found at brainly

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Speed of May = 250 meters per minute

Length of the track = 400 meters

2. How many minutes does it take May to complete 4 laps of the track?

Let's answer the question calculating the total distance and the time it took Mary to run around the track, this way:

Total distance = 4 * 400 = 1,600 meters

Time it takes May to run 1,600 meters = 1,600/250

Time it takes May to run 1,600 meters = 6.4 minutes

6.4 minutes = 6 minutes + 0.4 * 60 seconds = 6 minutes and 24 seconds

Time it takes May to run one lap = 6.4/4 = 1.6

1.6 minutes = 1 minute + 0.6 * 60 seconds = 1 minute and 36 seconds

Answer:

10.8 cm

Step-by-step explanation:

we know that

1) A square picture with side length 30 cm is scaled by 60% on a photocopier

Remember that

[tex]60\%=60/100=0.60[/tex]

so

The length of the first copy of the picture is

[tex]30(0.60)=18\ cm[/tex]

2) The copy is then scaled by 60% again

so

The length of the second copy of the picture is

[tex]18(0.60)=10.8\ cm[/tex]

Based on the information given, the side length of the second copy of the picture is 10.8cm.

Therefore, the side length will be:

= 30 × 60% × 60%

= 10.8cm

In conclusion, the correct option is 10.8cm.

Final answer:

Line a and line b, being parallel, have the same slope which is the defining feature of parallel lines.

Explanation:

When two lines, line a and line b, are parallel, they will never intersect and will have the same slope. Therefore, if line a is parallel to line b, the statement 'Line a and line b have the same slope' is true.

In the context of the slope of lines, the sum of the slopes of line a and line b would not be 0 unless both slopes are zero, which is typically not the case for non-horizontal lines. The product of the slopes would not be 1 or -1 either, unless one of the lines is perpendicular to the other, which would imply that the lines are not parallel. Therefore, the characteristic feature of parallel lines is that their slopes are identical.

Answer:

ax = 20 - 5

ax = 15

Hope it helpss!!

Final answer:

The two numbers that add up to 29, where one number is one more than the other, are 14 and 15. The equation 2x + 1 = 29 helped determine that the smaller number is 14, and adding one gives us the larger number, 15.

Explanation:

The two numbers in question are those that sum up to 29, and one number is one more than the other. Let's denote the smaller number as x, which makes the larger number x + 1 because it's one more than the smaller one. Setting up the equation based on the information given, we have:
x + (x + 1) = 29
Combining like terms gives us:
2x + 1 = 29
To find the value of x, we subtract 1 from both sides:
2x = 28
And then divide by 2:
x = 14
Therefore, the smaller number is 14, and the larger number, being one more than 14, is 15.

None of the above graph gives the function.

Step-by-step explanation:

The function is given by

f(x) = - x + 1 for, x ≤ 0  .......... (1) and

f(x) = x + 1 for, x > 0 ............. (2)

Now, from this definition we can write for x = 0, the value of f(x) will be governed by the equation (1) and f(0) = - 0 + 1 = 1

So, (0,1) is a point on the graph and for x < 0 the f(x) will have negative slope and for x > 0, the f(x) will have  positive slope.

Step-by-step explanation:

The correct question is

Suppose that ∅ Is an angle with csc(∅)=-12/5 and ∅ Is not in the third quadrant. Compute the exact value of Tan(∅).

∅ Is not in the third quadrant

If csc(∅) is negative the angle lie in the III Quadrant or in the IV Quadrant

∅ Is not in the third quadrant ----> given problem

so

That means ----> ∅ Is in the fourth quadrant

step 1

Find the value of [tex]sin(\theta)[/tex]

we have

[tex]csc(\theta)=-\frac{12}{5}[/tex]

we know that

[tex]csc(\theta)=\frac{1}{sin(\theta)}[/tex]

therefore

[tex]sin(\theta)=-\frac{5}{12}[/tex]

step 2

Find the value of [tex]cos(\theta)[/tex]

we know that

[tex]sin^2(\theta)+cos^2(\theta)=1[/tex]

we have

[tex]sin(\theta)=-\frac{5}{12}[/tex]

substitute
