Answer:

308

Step-by-step explanation:

Based on the given conditions, formulate: 7 x 572/13

Cross out the common factor: 7 x 44

Calculate the product or quotient: 308

Answer:

308

Step-by-step explanation:

572 divided by 13 is 44 which means there is 44 miles per gallon. So multiply 44 x 7 and you get 308 miles.

James took 97 minutes to clean his house. there were 12 rooms in the house, and it took him the same amount of time to clean each room. time  left after he finished cleaning is 4 hour 36 minutes

James took 97 minutes to clean his house.

there were 12 rooms in the house,

and it took him the same amount of time to clean each room

how much time did he have left after he finished cleaning?

one room clean =97 minutes

12 room clean = 97*12 amount of minutes

                        = 1164 minutes

                       = 19hour 24 minutes

James took 19 hour 24 minutes to clean 12 room

amount of time left = 24 hour - 19 hour 24 minutes

             = 4 hour 36 minutes

Adriel’s age if the sum of the square of adriel’s age and 4 times jevonte’s age is 85 is 7 years

Let the ages be x and x + 2 since they're consecutive odd integers.

We want to find Adriel’s age if the sum of the square of adriel’s age and 4 times jevonte’s age is 85. This will be illustrated as:

x² + 4(x + 2) = 85

x² + 4x + 8 = 85

Collect like terms

x² + 4x + 8 - 85

x² + 4x - 77 = 0

x² + 11x - 7x - 77 = 0

x(x + 12) - 7(x + 11) = 0

x - 7 = 0

x = 0 + 7

Therefore, the age is 7 years.

Answer:

8

Step-by-step explanation:

Let the number be “X"

Solution:

4 + (X/2) = 8

(X/2) = 8-4

(X/2) = 4

X = 4×2

X = 8

THEREFORE THE ANSWER IS “8”

Answer:

This is a simultaneous equation.

Step-by-step explanation:

let the first number be x and second be y

Lets make an equation first:

3x-y = 8 .....(1)

x+y = 12........(2)

Solve by elimination.

Dass

3x+x= 8+12

4x=20

x=5

find y

x+y=12

5+y=12

y=12-5

y= 7

Therefore the two numbers are 5 and 7

The equation of the perpendicular line that passes through (−10, 2) will be y = (5/4)x + 14.5.

If the slope of the line is m, then the slope of the perpendicular line will be negative 1/m.

The equation is given below.

4x + 5y = 15

5y = −4x + 15

y = −(4/5)x + 3

The slope of the equation is −4/5. Then the slope of the perpendicular line will be 5/4. Then the equation is given as,

y = (5/4)x + c

The equation that passes through (−10, 2) will be

2 = (5/4)(−10) + c

2 = −12.5 + c

c = 14.5

Then the equation of the perpendicular line that passes through (−10, 2) will be y = (5/4)x + 14.5.

The ratio of the number of words Li Zhen typed to the number of words Kara typed to the number of words Rose typed = 8 : 4 : 1

Total numbers of words Li Zhen, Kara and Rose typed = 156 words

What is Ratio ?

A ratio displays the multiplicity of two numbers. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. The ratio of oranges to the overall amount of fruit is 8:14, and the ratio of lemons to oranges is 6:8.

Since, it's given that

    the number of words Kara typed = 48

number of words Li Zhen typed = 2 x 48

                                                      =96words

a)  The ratio of the number of words Kara typed to the number of words Rose typed = 4:1

Since, it's given that

    the number of words Kara typed = 48

let, the number of words Rose typed = x

then, by equating them we get,

4/1 = 48/x

       4x = 48

          x = 48/4

          x = 12

The ratio of the number of words Li Zhen typed to the number of words Kara typed to the number of words Rose typed :

=  96 : 48 : 12

= 8 : 4 : 1

b) Now we know that,

  The number of words Li Zhen typed = 96words

  The number of words Kara typed = 48words

  The number of words Rose typed = 12words

Then, the total numbers of words Li Zhen, Kara and Rose type altogether

                               = 96 + 48 + 12

                               = 156 words

The woodworker should make atmost 4 rocking kitchen chair and 3 simple kitchen chair to maximize the profit under given conditions of 192 woodworking hours and 21 painting hours.

Profit maximization is a process that businesses go through to make sure the best levels of output and prices are realized in order to maximize their returns. The company modifies important variables like sale price, production costs, and output levels in order to achieve its profit objectives.

inequality, A mathematical statement expressing an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to etc.

Given,

Time needed to woodwork a rocking kitchen chair= 30 hours

Time needed to paint a rocking kitchen chair=3 hours

Time needed to woodwork a simple kitchen chair= 24 hours

Time needed to paint a simple kitchen chair=3 hours

Maximum time given by worker= 192 hours for woodwork and 21 hours to paint

Let x and y be the maximum number of chairs created by woodworker of both the types.

so the system of inequality would be,

30x+24y<192      ......(1)

3x+3y<21             ......(2)

To find x and y,

multiply the (2) by 10

30x+30y<210

subtract (1) from (2)

30x+24y-(30x+30y)<192-210

-6y<-18

y<3

3x+3y<21

3x+3*3<21

iq scores have a bell shape distribution with a mean of 100 and standard deviation of 15. 81.855%  of the population has an iq score between 70 and 115

What is z-score?

The z score, also referred to as the standard score, serves to calculate how far each data point place is from its mean. In other words, it calculates x's (data point's) deviation in terms of standard deviations.

Using z tables, you may calculate the proportion of the population that is either below or above the score.

Now, according to the question;

IQ scores follow a normal distribution, with a mean of 100 as well as a standard deviation = 15.

A z score is determined as follows:

z = (x - μ)/σ

μ = mean of the distribution

σ = standard distribution of the sampling.

Calculation for the z score for x = 70 and  115

z= (70-100)/15

= -30/15

=-2

and x=115

z = (115 - 100)/15

= 15/15

z = 1.0

Use z-score table, then likelihood that a randomly chosen person's IQ is more than 115 is,

P( -2 < z < 1)= P(z<1) - P(z< -2)

                   =  0.8413 - 0.02275

                  = 0.81855

Therefore, the percent of the population has an iq between 70and 115 is 81.855%.

even if an independent variable has an effect on the dependent variable, it fail to reject the null hypothesis and make a type II error

Even if a treatment is effective in the real world (it has an effect), it is still possible to obtain a sample mean that is so similar to the population mean that the sample mean doesn't fall in the critical, or rejection, region. If this happens, you are likely to fail to reject the null hypothesis and make a type II error.

Since that sample mean is so similar to the population mean, the treatment effect may not be detected on analysis even though it is in fact significant, this will cause the research to erroneously concluded that the treatment effect is zero and accept the null hypothesis when it is actually not zero. This is a type II error. Type II error in statistics means the non-rejection of a false null hypothesis and type I error is the rejection of a correct null hypothesis.
