Find the value of x in the triangle shown below. x = 56° 99°​

Answer:

-7

Step-by-step explanation:

Answer:

d = 7

Step-by-step explanation:

1.5d + 9.25 = 4 + 2.25d

Combine the constants and the variables.

5.25 = 0.75d

Divide.

d = 7

Answer:

The value is  [tex]\sigma _x = 1.1832[/tex]

Step-by-step explanation:

From the question we are told that

   The  population mean is [tex]\mu = 25[/tex]

    The population standard deviation is  [tex]\sigma = 7[/tex]

    The sample size is  n =  35

Generally the standard deviation of the sampling distribution is mathematically represented as

       [tex]\sigma _x = \frac{\sigma}{\sqrt{n} }[/tex]

=>    [tex]\sigma _x = \frac{7}{\sqrt{35} }[/tex]

=>    [tex]\sigma _x = 1.1832[/tex]

Answer:

20 hat packs and 12 shirt packs

Step-by-step explanation:

Scout total troops of boys is 60

Hat come in packs is 3 and shirts come packs of 5 .Thus answer to above question 20 hats and 12 shirts at least

Explanation:

Answer:

The p- value  is [tex]p-value  =  0.2033[/tex]

Its interpretation is  

As  [tex]p-value > \alpha[/tex]

The decision rule is

Fail to reject the null hypothesis

 The conclusion is  

There is no  sufficient evidence to support the  company claims at a level of  sign9ificance of 0.05

Step-by-step explanation:

From the question we are told that

  The mean is  [tex]\mu =  30 \  inches[/tex]

  The standard deviation is   [tex]\sigma  =  1.2 \  inches[/tex]

  The sample size is  n  =  100

  The sample mean is  [tex]\= x  =  30.1[/tex]

Let assume the level of significance is  [tex]\alpha = 0.05[/tex]

The null hypothesis is [tex]H_o  :  \mu \le 30[/tex]

The alternative is  [tex]H_a : \mu > 30[/tex]

Generally the test test is mathematically represented as

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

=>  [tex]z =  \frac{30.1- 30 }{\frac{1.2}{\sqrt{100} } }[/tex]

=>  [tex]z =  0.83[/tex]

Generally from the z-table  the  probability of (Z > 0.83 ) is

   [tex]p-value  =  0.2033[/tex]

From the value obtained we see that  [tex]p-value > \alpha[/tex] hence

 The decision rule is

Fail to reject the null hypothesis

 The conclusion is  

There is no  sufficient evidence to support the  company claims at a level of  sign9ificance of 0.05

Answer:

[tex]7x\leq x-24[/tex]

Here, [tex]x[/tex] denotes the required number.

Step-by-step explanation:

Let [tex]x[/tex] denotes the required number that satisfies the following condition.

''seven times a number is less than or equal to a quantity that is 24 less than that same  number''

Seven times a number is equal to [tex]7x[/tex]

Quantity that is 24 less than that same  number is equal to [tex]x-24[/tex]

Now find the inequality.

As seven times a number is less than or equal to a quantity that is 24 less than that same  number,

[tex]7x\leq x-24[/tex]

Answer:

Yes its less than 0

Answer:

3.75 cups of sugar. I think

Answer:

3 3/4

Step-by-step explanation:

3/5 times 5

1.multiiply the numerator by 5

The numerator is the top number which is 3 in this case

So 3x5 is 15

You keep the denominator 4

so 15/4 that is an improper fraction now divide 15 by 4

or count by fours

4,8,12,16

16 is more than 15 so the new numerator is 12 and how many times did we count to fours? 3 times

so 3 is a whole now subtract the 12 you already took with 15. 3 is the extra so 3 wholes and 3 extras which is 3 3/4

*remember you keep the denominator the same

Answer:

Rita earns 10 points at the end of the play.

Bernie losses 35 points.

Step-by-step explanation:

Rita earns 6 points 3 time and loses 4 points twice

6 * 3 = 18

4 * 2 = 8

18 - 8 = 10 points

Bernie get bonus of 15 points

looses 25 points twice

15 -  (25 * 2) = -35 points

Answer:

¾(y + 3) + 9w

Step-by-step explanation:

Let's write it step by step:

Step 1: Three fourths of the sum of y and 3 is; ¾(y + 3)

Step 2: plus the product of 9 and w is;

¾(y + 3) + 9w

Thus,the final algebraic expression of the statement given in the question is;

¾(y + 3) + 9w

Answer:

1/2 liters

Step-by-step explanation:

Rosanne makes 1 1/2 liters of strawberry lemonade

She pours 1/4 of the lemonade into a thermos

The quantity left is

= 1 1/2 - 1/4

= 3/2 - 1/4

= 5/4

Her brother drinks 2/5 of the remaining lemonade

Therefore the quantity of lemonade that Rosanne brother drinks can be calculated as follows

= 2/5 × 5/4

=1/2

Hence the quantity of lemonade that Rosanne brother drinks is 1/2 liters

Answer:

1/2 liters

Step-by-step explanation: Rosanne makes 1 1/2 liters of strawberry lemonade

She pours 1/4 of the lemonade into a thermos

The quantity left is

= 1 1/2 - 1/4

= 3/2 - 1/4

= 5/4

Her brother drinks 2/5 of the remaining lemonade

Therefore the quantity of lemonade that Rosanne brother drinks can be calculated as follows

= 2/5 × 5/4

=1/2

Answer:

We will need two equations, one that adds up to the total number of marbles, and the other which writes one type of marbles in terms of the other.

For the first equation we know that:

[tex]r + b = 42[/tex]

For the second we are told that "The number of red marbles she has is three  more than twice the number of black marbles she has."

So we simply translate this into an equation being:

[tex]r = 2b + 3[/tex]

What happens to

- the angles on a shape

- the lines on the shape

- the shape itself

when the shape is transformed?

ANSWER:

- When a shape is transformed, the angles on the shape either increase or reduce in size

- When a shape is transformed, the lines on the shape change direction. They could also be shorter, longer, more curved, or more flattened.

- When a shape is transformed, the shape itself becomes another one.

Answer:

  y = 55°

Step-by-step explanation:

You know the sum of angles in a triangle is 180°. So, ...

  25° +30° +x = 180°

And, you know a linear pair of angles totals 180°:

  x + y = 180°

Substituting for 180°, we have ...

  25° +30° +x = x + y

Subtracting x from both sides, we get a relation that is useful to remember:

  25° +30° = y

  y = 55°

_____

This relation is usually described as ...

  An exterior angle is equal to the sum of the remote interior angles.
