Divide the number 90 into three parts in the ratio 1:4:5.

Answers

Answer 1

Answer:

9, 36, and 45

Step-by-step explanation:

The order is 9, 36, and 45 because as we have to divide 90 into 1:4:5, 1+4+5=10 total parts. Then 90 divided by 10 equals to 9. The first number has 1 part, so 9x1=9 for the first number. For 4 parts, 9x4=36 for the second number. For 5 parts, 9x5=45 for the third number. The order is 9, 36, and 45. Hope it helps!

Answer 2

When we divide 90 in 1:4:5 ratio so it comes 9,36, and 45.

Given that,

The number is 90. We have to divide the above number in 1:4:5 ratio.

Based on the above information, the calculation is as follows:

x + 4x + 5x = 90

10x = 90

x = 9

Now multiply each ratio with 9 to get each value.

So, the values should be 9,36, and 45.

Therefore we can conclude that when we divide 90 in 1:4:5 ratio so it comes 9,36, and 45.

Some teenagers collected trash for a beach clean-up. The data for the number of pounds of trash collected by each teenager are shown below.

26, 26, 21, 22, 20, 25, 35

What is the range of the data?

Answers

Answer:

D. 15 pounds

Step-by-step explanation:

35-20=15

The range of the data that represents the number of pounds of trash collected by each teenager is 15.

What is the range of a data set?

The range is the difference between the Maximum value of the data set and the Minimum value of the dataset. Therefore, we can write the range as,

Range = Maximum value of the data set - Minimum value of the dataset

Given the data for the number of pounds of trash collected by each teenager as 26, 26, 21, 22, 20, 25, and 35.

Now, from the data, the Maximum value of the data set is 35 and the Minimum value of the dataset is 20. Therefore, we can write the range of the data set as,

Range = Maximum value of the data set - Minimum value of the dataset

          = 35 - 20

          = 15

Hence, the range of the data that represents the number of pounds of trash collected by each teenager is 15.

an inspector tested the first 125 radios that came off the production line today and found only 60% acceptable. After the inspector tested 25 more radios, the overall percentage of acceptable radios rose to 62%. The number of these 25 radios that were rejected is???

Answers

Answer: 7 radios

Step-by-step explanation:

The following can be deduced from the question:

Number of radios tested = 125 radios

Percentage acceptable = 60%

Numbers acceptable:

= 60% × 125

= 0.6 × 125

= 75 radios

Numbers rejected = 125 - 75 = 50 radio

We are further told that the inspector tested 25 more radios, this will be:

Number of radios tested

= 125 + 25 = 150 radios

Percentage acceptable = 62%

Numbers acceptable

= 62% × 150

= 0.62 × 150

= 93 radios

Numbers rejected= 150 - 93 = 57 radios

The number of these 25 radios that were rejected will be:

= 57 - 50

= 7 radios

Null hypothesis: The proportion of Americans that have seen a UFO is equal to 2 in a thousand.

Alternative hypothesis: The proportion of Americans that have seen a UFO is less than 2 in a thousand.

Type I error is the rejection of true null hypothesis so, in this case type I error is rejection of claim  that the proportion of Americans that have seen a UFO is equal to 2 in a thousand when that proportion is actually 2 in a thousand.

The radius of the circle is 2 inches.

[tex]r= 2 \ in[/tex]

Substitute the value into the formula.

[tex]a=\pi ( 2 \ in)^2[/tex]

break Abdul-Jabbar's career record?

Answers

Answer:

Step-by-step explanation:

LeBron James need to play to 1444 games to break Abdul-Jabbar's career record.

What is rate of change?

A rate of change is a rate that describes how one quantity changes in relation to other.

Given world record Kareem Abdul-Jabbar = 38,387 points.

Games played by LeBron = 280 games

Score of LeBron = 7446 points

Hence for each point LeBron has to play = 280/7446 games

Therefore to break the world record number of games required

                                       = (280*38,387)/7446

number of games required = 1443.5

or, number of games required = 1444

Hence,at this rate LeBron James need to play to 1444 games to break Abdul-Jabbar's career record.
