Which number satisfies the inequality 9h + 15 > 55?

Answers


When you say "Which number ...", I expect to see a list of choices at the
end of the question, and I get very upset when there's nothing there.

                                            9h + 15 > 55

Subtract  15  from each side:          9h > 40

Divide each side by  9 :                    h > 40/9

Any number greater than (4 and 4/9) satisfies the inequality.
9h + 15 > 55
      - 15 - 15
         9h > 40
          9      9
           h > 4⁴/₉

The solution set is equal to (4⁴/₉, ∞).

A number is doubled and then decreased by 13. the result is 61. what is the ordinal number?

Answers

let x be the number
x + x - 13 = 61
2x - 13 = 61
2x = 61 + 13
2x = 74
2x/2 = 74/2
x = 37
i would use the inverse operation.
61 divided by 2 plus 13 equals 43.5  

The table shows the ages and weights of babies at a hospital. What is the correlation between age and weight as shown in the table?

A.) none

B.) positive

C.) negative

D.) constant

Answers

Answer:

Option (b) is correct.

The correlation between age and weight  shown in the table is positive.

Step-by-step explanation:

Given: The table shows the ages and weights of babies at a hospital.

We have to determine the  correlation between age and weight as shown in the table.

We first  Plot these points to obtain the graph as show in attachment below.

Since, Using correlation calculator , we find the correlation  as 0.83113

Which is positive

Thus,  The correlation between age and weight  shown in the table is positive.

As age increases the weight increase.Hence, positive.

 

The correlation between age and weight as shown in the table is positive, This is further explained below, Option B is correct

What is correlation?

Correlation is simply a relationship that exists between events or objects, A relationship between mathematical variables that are subject to variation.

In conclusion, Therefore we look at the table to decipher the correlation between age and weight.

In the first 42 Super Bowls, 0.16(repeating sign over 6) of the MVPs were running backs.a. What percent of the MVPs were running backs? Write the percent as a mixed number.

b. What fraction, in simplest form, of the MVPs were not running backs?

Answers

0.16 (repeating sing over 6) is a decimal number. It represents the running backs among the MVP.

1) It can be converted into its percentage form by multiplying it with 100%. 

0.1666 x 100% = 16.66%  of the MVP are running backs.

2) 1 - 0.1666 = 0.8334 is the decimal number for MVPs who were not running backs.

Its fraction form is 0.8334/1.000 or 83.34% of the MVPs were not running backs.

2 sin x cos2x - 1 + 2 sin2x
2 sin x cos2x - sin x + 1 - 2 sin2x
2 sin x cos2x - 1 - 2 sin2x

Answers

Note that
sin 2x = 2 sin(x) cos(x)
cos 2x =  cos²x - sin²x = 2cos²x - 1 = 1 - 2sin²x

Therefore
sin 2x -  cos 2x
= 2 sin(x) cos(x) - (1 - 2sin²x)
= 2 sin(x) cos(x) - 1 + 2sin²x

Answer: 2 sin(x) cos(x) - 1 + 2 sin²x
