The value of x in the given right triangle is 11.

A triangle in which one of the interior angles is 90° is called a right triangle. The longest side of the right triangle, which is also the side opposite the right angle, is the hypotenuse and the two arms of the right angle are the height and the base.

Given is a right triangle, with angles 5x-2 and 3x+4

We know that the sum of the both acute angles of a right triangle, is 90°

Therefore,

5x-2 + 3x+4 = 90°

8x = 88

x = 11

Hence, the value of x in the given right triangle is 11.

Answer:

Sample B is much bigger than Sample A

Step-by-step explanation:

It is because when seeing sample B alone we can see it has a larger mean than of Sample A. Mean is greater when the values we are using are of bigger value. Since Sample B has bigger values in it so it also a has bigger mean compared to Sample A which has a smaller mean (smaller values in it)

Answer:

x = -8

Step-by-step explanation:

using what's given, you can make the following equation:

3 + 2x + 22 = x + 17

3 + 22 + 2x - x = 17

25 + x = 17

x = 17 - 25

x = -8

Answer:

Step-by-step explanation:

3 + 2x + 22= x + 17

2x + 25 = x + 17

x + 25 = 17

x = -8

3 + 2(-8) + 22 = -8 + 17

25 - 16 = 9

9 = 9

Answer:

Step-by-step explanation:

f(x) = 2 |5(-4)+7| -1

     = 2 |(-20)+7| -1

     = 2 | -13 | -1

     = 26 - 1

     = 25

A function assigns the value of each element of one set to the other specific element of another set. The value of the function f(-4) is 25.

A function assigns the value of each element of one set to the other specific element of another set.

The value of f(-4) can be evaluated by substituting the value of x as -4 in the given function, therefore, the value of f(-4) can be written as,

f(x) = 2|5x+7| − 1

f(-4) = 2|5(-4)+7| − 1

      = 2|-20 + 7| - 1

      = 2|-13| - 1

      = 2(13) - 1

      = 26 - 1

      = 25

Hence, the value of the function f(-4) is 25.

Answer:

Question 1

The correct option is  A

Question two

 The correct option is B

Question three

   [tex]SE= 0.5[/tex]  

Question four

   [tex]z = - 3 [/tex]

Question five

The correct option is A

Step-by-step explanation:

   The population mean is  [tex]\mu =  50 \ grams[/tex]

   The sample size is  n = 16

   The population size is N  = 4000

   The sample mean is  [tex]\= x  =  48.5 \grams[/tex]

   The standard deviation is [tex]s  =  2 \ gram(s)[/tex]

Considering the first question

 The correct option is  A

z test because the SD of the population is known and the weights follow the normal curve

Considering  the second question

The correct option is  B

Yes, because with only 20 observations the sample SD is not a great estimate of the true population SD.

Considering  the third question  

   Generally the standard error is mathematically represented as

         [tex]SE= \frac{s }{\sqrt{n} }[/tex]

=>      [tex]SE= \frac{2 }{\sqrt{16} }[/tex]

=>       [tex]SE= 0.5[/tex]    

The null hypothesis is  [tex]H_o :  \mu  =  50[/tex]

The alternative  hypothesis is  [tex]H_a :  \mu  <  50[/tex]

Generally the test statistics is mathematically represented as

      [tex]z = \frac{ \= x  - \mu  }{ SE }[/tex]

=>    [tex]z = \frac{ 48.5 - 50 }{ 0.5}[/tex]

=>   [tex]z = - 3 [/tex]

Generally the p-value is mathematically represented as

     [tex]p-value  = P(Z <  z )[/tex]

=>  [tex]p-value  = P(Z <  - 3  )[/tex]

From the z-table the

    [tex]P(Z <  - 3  ) =0.0013499[/tex]

=>  [tex]p-value  = 0.0013499[/tex]

From the obtained values we see that

  [tex]p-value  <  \alpha[/tex]

So we reject the null hypotheses

The conclusion

it's very unlikely that the factory is making the candy bars 50 grams as they claim

Testing the hypothesis, we have that:

At the null hypothesis, we test if the factory is doing what it is supposed to, that is, the mean is of 50 grams, hence:

[tex]H_0: \mu = 50[/tex]

At the alternative hypothesis, we test if the factory is cheating the customer, that is, the mean is of less than 50 grams, hence:

[tex]H_1: \mu < 50[/tex]

We have the standard deviation for the population, thus, the z-distribution is used. The test statistic is given by:

[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

The parameters are:

For this problem, the values of the parameters are: [tex]\overline{x} = 48.5, \mu = 50, \sigma = 2, n = 16[/tex]

Hence, the standard error is:

[tex]S_e = \frac{2}{\sqrt{16}} = 0.5[/tex]

The value of the test statistic is:

[tex]z = \frac{\overline{x} - \mu}{S_e}[/tex]

[tex]z = \frac{48.5 - 50}{0.5}[/tex]

[tex]z = -3[/tex]

The critical value for a left-tailed test, as we are testing if the mean is less than a value, with a significance level of 0.05, is of [tex]z^{\ast} = -1.645[/tex]

Since the test statistic is less than the critical value for the left-tailed test, we can reject the null hypothesis.

Answer:

Step-by-step explanation:

y=-5x+12

10x+2y=-2

Subtract 10x to the other side of the equation and you will get 2y=-10x-2

Then divide both side by 2 to get y by itself

It will lead you to y=-5x+1

Notice that your point is (0,12) and it says parallel so you will keep your slope but your y-intercept will change

Final answer: y=-5x+12

I believe it's y= -5x+12. I really hope this helps. Happy schooling!!

Answer:

$89.70

Step-by-step explanation:

To solve this equation, let's formulate a linear equation.

Let [tex]b[/tex] equal bags of mulch.

Let [tex]t[/tex] equal the total amount.

We know the price of each bag of mulch ($4.98), so we can represent this as:

[tex]4.98b[/tex]

We also know that there's a fee of $15, so we can just represent this as:

[tex]15[/tex]

Let's put these values into an equation:

[tex]t=4.98b+15[/tex]

Now with an equation, we know that she purchases a total of 15 bags, so let's substitute [tex]15[/tex] for [tex]b[/tex]:

[tex]t=4.98(15)+15[/tex]

Multiply:

[tex]t=74.70+15[/tex]

Add:

[tex]t=89.70[/tex]

_

Check your work by substituting the total amount into the initial equation:

[tex]89.70=4.98b+15[/tex]

Subtract [tex]15[/tex] from both sides of the equation:

[tex]74.70=4.98b[/tex]

Divide both sides of the equation by the coefficient of [tex]b[/tex], which is [tex]4.98[/tex]:

[tex]15=b[/tex]

Amber did in fact purchase 15 bags, so we know our total amount is correct!

Answer:

0, π, 2π, π/6 and 5+(π/6)

Step-by-step explanation:

Rearranging, sinx (2 sinx - 1) = 0.

In [0, 2π],sin x = 0 for x = 0, π and 2π.

The other factor = 0 gives the other two solutions.

sin 5+(π/6) = sin (π−(π-6)) = sin π/6 = 1/2.

Answer:

Step-by-step explanation:

The slope is achieved through (5-3)/((0-(-1)) which is 2. The y-intercept is just where x=0 on the equation so (0,5). 3. Put it all together in y=mx+b to get 2x+5. Hope that helps!

Answer:

a = 2 hours and 9 minutes

Explanation:

(using fractions)

45 minutes + 1 2/5 hours = 3/4 hours + 7/5 hours = 15/20 + 28/20 = 43/20 = 2 3/20 = 2 9 /60 = 2 hours 9 minutes.

(using decimals)

45 minutes + 1 2/5 hours =

0.75 hours + 1.4 hours = 2.15 hours = 2 hours 9 minutes.

since .15 × 60 = 9 .

Also keep in mind that there are 60 minutes in an hour.
