Answer:

infinite solutions

Step-by-step explanation:

3+4(5−x)=19−4x+4

Distribute

3 +20 -4x = 19 -4x +4

Combine like terms

23 -4x = 23 -4x

Add 4x to each side

23-4x+4x = 23-4x+4x

23 =23

This is always true so there are infinite solutions

Step-by-step explanation:

Answer:

The height is 12 feet.

Step-by-step explanation:

The formula for area of a triangle is 1/2 ⋅ b (base) ⋅ h (height).

Now let's plug in the numbers.

According to the word problem, the base is 12 feet.

As of now, our equation is: 1/2 ⋅ 12 ⋅ h

The only number times 1/2 that would give you an answer of 72 is 144.

12⋅12 = 144.

This means the height is 12.

And, 1/2 ⋅ 12 ⋅ 12 ⋅ = 72.

Because the area of the triangle is 72, 72 is the number we are looking for.

Therefore, the height is 12.

I really hope this made sense, it was a bit rushed.

When we do this, the base of the parallelogram has length b 1 + b 2, and the height is the same as the trapezoids, so the area of the parallelogram is (b 1 + b 2)*h. Since the two trapezoids of the same size created this parallelogram, the area of one of those trapezoids is one half the area of the parallelogram

Answer:

Step-by-step explanation:

Answer:

Angle A = 68 degree

Angle B = 44 degree

Step-by-step explanation:

Sum of all interior angles = Angle A+Angle B+ Angle C

180 = 68+x+x-24

180 = 68+2x-24

180-68 = 2x-24

112+24 = 2x

136/2 = x

68 = x

Therfore, Angle A = 68 degree

Angle B = (x-24)

= (68-24)

= 44 degree

Answer:

A = 4.5

B = 40.5

C = 4π or 12.566

D = 16

Step-by-step explanation:

A

6 x .5 = 3

3 x .5 = 1.5

1.5 x 3 = 4.5

B

12 x 3/4 = 9

1/2 (9)(9) = 40.5

C

8 x .25 = 2

π2² = 4π or 12.566

D

24 x 1/3 = 8

6 x 1/3 = 2

2 x 8 = 16

your answer should be 0.80

Subtract 6 from the total then divide by 2.

34-6 = 28

28/2 = 14

The length of the other two sides are 14 cm each

Answer:

i think that's right

Step-by-step explanation:

Answer:

a) By the Central Limit Theorem, it is approximately normal.

b) The standard error of the distribution of the sample mean is 1.8333.

c) 0.1379 = 13.79% of the samples will have a mean useful life of more than 38 hours.

d) 0.7939 = 79.39% of the samples will have a mean useful life greater than 34.5 hours

e) 0.656 = 65.6% of the samples will have a mean useful life between 34.5 and 38 hours

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

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

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Mean of 36 hours and a standard deviation of 5.5 hours.

This means that [tex]\mu = 36, \sigma = 5.5[/tex]

a. What can you say about the shape of the distribution of the sample mean?

By the Central Limit Theorem, it is approximately normal.

b. What is the standard error of the distribution of the sample mean? (Round your answer to 4 decimal places.)

Sample of 9 means that [tex]n = 9[/tex]. So

[tex]s = \frac{\sigma}{\sqrt{n}} = \frac{5.5}{\sqrt{9}} = 1.8333[/tex]

The standard error of the distribution of the sample mean is 1.8333.

c. What proportion of the samples will have a mean useful life of more than 38 hours?

This is 1 subtracted by the pvalue of Z when X = 38. So

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

By the Central Limit Theorem

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

[tex]Z = \frac{38 - 36}{1.8333}[/tex]

[tex]Z = 1.09[/tex]

[tex]Z = 1.09[/tex] has a pvalue of 0.8621

1 - 0.8621 = 0.1379

0.1379 = 13.79% of the samples will have a mean useful life of more than 38 hours.

d. What proportion of the sample will have a mean useful life greater than 34.5 hours?

This is 1 subtracted by the pvalue of Z when X = 34.5. So

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

[tex]Z = \frac{34.5 - 36}{1.8333}[/tex]

[tex]Z = -0.82[/tex]

[tex]Z = -0.82[/tex] has a pvalue of 0.2061.

1 - 0.2061 = 0.7939

0.7939 = 79.39% of the samples will have a mean useful life greater than 34.5 hours.

e. What proportion of the sample will have a mean useful life between 34.5 and 38 hours?

pvalue of Z when X = 38 subtracted by the pvalue of Z when X = 34.5. So

0.8621 - 0.2061 = 0.656

0.656 = 65.6% of the samples will have a mean useful life between 34.5 and 38 hours

Answer:

12

Step-by-step explanation:

Hello There!

When we are given two side lengths and the included angle we use this formula to solve for the area

[tex]A=\frac{1}{2} absin(C)[/tex]

where a and b = the side lengths and c = the included angle

The triangle gives us the following information

side length - 10 ft

side length - 4 ft

included angle - 37

Given this information we plug it into the formula

[tex]A=\frac{1}{2} 4*10sin(37)\\10*4=40\\40sin(37)=24.07260093\\\frac{24.07260093}{2} =12.03630046[/tex]

Finally we round to the nearest tenth and get that the area of the triangle is 12ft²

Answer:

x = 3 and x = -2

Step-by-step explanation:

The given equation is :

[tex]x^2-x-6=0[/tex]

We need to solve the given equation.

We can solve it using Completing the Square method.

We take two numbers such that their product is -6 and sum is -1.

So,

[tex]x^2-x-6=0\\\\x^2+2x-3x-6=0\\\\x(x+2)-3(x+2)=0\\\\(x-3)(x+2)=0\\\\x=3\ and\ x=-2[/tex]

so, the values of x are 3 and -2.

Given:

The equation is:

[tex]\log_{(x-2)}(x^2-4x-6)=\dfrac{4}{5}[/tex]

To find:

The exponential equation of the given logarithmic equation.

Solution:

We have,

[tex]\log_{(x-2)}(x^2-4x-6)=\dfrac{4}{5}[/tex]

According to property of logarithm,

[tex]\log_ax=b\Leftrightarrow x=a^b[/tex]

Using the property of logarithm, we get

[tex]x^2-4x-6=(x-2)^{\frac{4}{5}}[/tex]

Therefore, the required exponential equation is [tex]x^2-4x-6=(x-2)^{\frac{4}{5}}[/tex].

Answer:

The value of g(2.7) is 31.49.

Step-by-step explanation:

Translations of a function:

Suppose that we have a function f(x).

The translation of f(x) a units to the left is given by g(x) = f(x+a).

The translation of f(x) a units to the right is given by g(x) = f(x-a).

The translation of f(x) a units up is given by g(x) = f(x) + a.

The translation of f(x) a units down is given by g(x) = f(x) - a.

Suppose the graph of f(x)=x^2 is translated 3 units right and 1 unit down.

Three units right:

[tex]g(x) = f(x+3) = (x+3)^2[/tex]

One unit down:

[tex]g(x) = f(x+3) - 1 = (x+3)^2 - 1[/tex]

What is the value of g(2.7)?

This is g when [tex]x = 2.7[/tex]. So

[tex]g(2.7) = (2.7+3)^2 - 1 = (5.7)^2 - 1 = 31.49[/tex]

The value of g(2.7) is 31.49.

first move the 2x to the other side and you get 2y=4-2x, then you divide the entire equation by 2 and get y=2-x, which when re arranged is y = -x+2.

Answer:

2π/3 radians is equal to 120°.

Step-by-step explanation:

In this problem, we need to convert the angle 2π/3 radians to degrees.

The relation radian and degree is given by :

[tex]D=\dfrac{180}{\pi}\times R[/tex]

Substitute all the values,

[tex]D=\dfrac{180}{\pi}\times \dfrac{2\pi }{3}\\\\D=120^{\circ}[/tex]

So, 2π/3 radians is equal to 120°.

You will get 2x+2y=24. add it with the equation below. y will be eliminated and you will get the value of x. X=10. Plug in x and get the y value. Y=2

Answer:

1

Step-by-step explanation:

Given that,

[tex]a=3+2\sqrt{2}[/tex]

We need to find the value of [tex]a\times \dfrac{1}{a}[/tex].

So,

[tex]=3+2\sqrt{2} \times \dfrac{1}{3+2\sqrt{2}}\\\\=\dfrac{3+2\sqrt{2}}{3+2\sqrt{2}}[/tex]

As numerator and dinominator is same. It means,

[tex]=\dfrac{3+2\sqrt{2}}{3+2\sqrt{2}}\\\\=1[/tex]

So, the value of the given expression is equal to 1.
