Using the linear equation: y-5= -2(x-6)
What is the slope of this line?_______

Convert the equation into Slope Intercept form. y =_______

What is the y-intercept of the equation? (0,____)

I'm not sure what you're really talking about.

But I think you are talking about fractions.

In fractions there are two places

The number that goes on the top is numerator.

Answer:

X/y = 2/5

Y= x+12

Where y = students

X= adults

Number of adults= 8

Number of students= 20

Step-by-step explanation:

The ratio of adults to students on a class field trip is 2 to 5. If there are 12 more students than adults.

Let adult be x

Let student be y

X/y = 2/5

5x= 2y.... equation one

Y= x+12..... equation two

Substituting equation two into equation one

5x= 2(x+12).

5x = 2x +24

3x= 24.

X= 8

Y= x+12

Y= 8+12

Y= 20

Number of adults= 8

Number of students= 20

Answer:

0.137.

Step-by-step explanation:

Given that

Sample size = 1100

Afraid to fly = 10 %

Mean = n x p

Mean = 1100 x 0.1 = 110

Variance = n p q

Variance = 1100 x 0.1 x 0.9 = 99

Standard deviation = [tex]\sqrt{n\times p\times q}[/tex]

S.D.=[tex]\sqrt{1100\times 0.1\times 0.9}[/tex]

S.D.=9.94

By using Normal distribution

[tex]Z=\dfrac{X-\mu}{\sigma}[/tex]

[tex]Z=\dfrac{121-110}{9.94}[/tex]

Z=1.16

[tex]P(X>121)=P(Z>1.16)=1-0.8643\\P(X>121)=0.137\\[/tex]

Thus the answer will be 0.137.

Answer:

19

Step-by-step explanation:

10 + 9 = 19. If you look at how many students are above the "30 mark", you will count 10 on the first bar and 9 on the second.

Step-by-step explanation:

y is the number of gallons left in the tank.

x is the number of hours you have been driving

Rate of consumption of gas

= (18 - y / x)

= 5 / 3 gallon per hour

= 6.309 L / hr

The rate at which your truck is using gas is 5/3 gallons per hour.

The rate at which your truck is using gas is calculated as follows;

Given that after 6 hours of driving, you have 8 gallons left in the tank, we can set up the following equation using the two given data points:

(Initial gallons - Remaining gallons) / (Initial time - Time elapsed) = (Change in gallons) / (Change in time)

The equation becomes;

Rate = (18 gallons - 8 gallons) / (6 hours - 0 hours)

Rate = (18 - 8) / 6

Simplifying this equation, we get:

Rate = 10 / 6

Rate = 5 / 3

Therefore, the rate at which your truck is using gas is 5/3 gallons per hour.

he got 0.08 percent questions correct

Answer:

72%

Step-by-step explanation:

A percentage is a number out of 100.  For example, 32/100 is 32%.  What you want to do with percentages is multiply the denominator of a fraction so it becomes 100 and multiply that same number to the numerator.  Sort of like a ratio!

If Mark got 18/25, we can multiply 25 by 4 to get 100 as the denominator.

Since you multiplied the denominator by 4, you have to multiply the numerator by 4 as well.  

18 times 4= 72.  So the numerator is 72 and the denominator is 100.  The fraction is 72/100, which is 72% since it is out of 100.

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

Definitely not.  -35 degrees is far below freezing (+32 degrees).  On the other hand, +35 degrees is very warm indeed.

No, the temperature of 35 degrees Fahrenheit is not as cold as a temperature of -35 degrees Fahrenheit.

We have temperature in degrees Fahrenheit.

We have to investigate - " Is a temperature of 35 degrees Fahrenheit as cold as a temperature of -35 degrees Fahrenheit ".

The formula is -

(°F − 32) × 5/9 = °C

According to the question -

Assume that -

A = 35°F = 1667 °C

B = -35°F = -37.2222 °C

The temperature 35°F represents very very high temperature (hot) whereas the  temperature  -35°F represents very very low temperature (cold).

Hence, No, the temperature of 35 degrees Fahrenheit is not as cold as a temperature of -35 degrees Fahrenheit.

The final expression after applying the distributive property is 7x-3

According to this property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Given here: The expression as 4+7(x-1)

The distributive property tells us how to solve expressions in the form of a(b + c).  

Now applying distributive property and solving for like terms we get :

Answer:

The  probability is  [tex]P(\$20,000 < X < \$35,000) = 0.6[/tex]

Step-by-step explanation:

From the question we are told that

     Workers' salaries in your company are uniformly distributed between $15,000 and $40,000 per year

  Generally the probability that a randomly chosen worker earns an annual salary between $20,000 and $35,000 is mathematically represented as

        [tex]P(\$20,000 < X \$35,000) = \frac{ 35000 - 20000}{ 40000 - 150000}[/tex]

  => [tex]P(\$20,000 < X < \$35,000) = 0.6[/tex]

Using the uniform distribution, it is found that there is a 0.6 = 60% probability that a randomly chosen worker earns an annual salary between $20,000 and $35,000.

An uniform distribution has two bounds, a and b.  

The probability of finding a value between c and d is:

[tex]P(c \leq X \leq d) = \frac{d - c}{b - a}[/tex]

In this problem, uniformly distributed between $15,000 and $40,000, hence [tex]a = 15, b = 40[/tex].

The desired probability is:

[tex]P(20 \leq X \leq 35) = \frac{35 - 20}{40 - 15} = 0.6[/tex]

0.6 = 60% probability that a randomly chosen worker earns an annual salary between $20,000 and $35,000.
