At midnight in Alaska, the temperature in Sitka is 29.7 degrees Fahrenheit.
Each hour after that the temperature decreases by 1.23 degrees until the sun comes up.
What is the temperature 2 hours after midnight?

Answers

Temperature

Level : JHS

the temperature in Sitka 2 hours after midnight is :

= 29.7°F + (2 × 1.23°F)

= 29.7°F + 2.46°F

= 32.16°F

So, the temperature in Sitka 2 hours after midnight is 32.16°F

#LearnWithEXO

Answer:

27.24° F

Step-by-step explanation:

Initial temperature = 29.7° FDecrease rate = 1.23° F / h

After 2 hours the temperature is:

29.7° F - 2*1.23° F = 27.24° F

An airport has an electronic system that randomly selects bags for extra security screening. Each bag has a 14% percent probability of being selected for extra screening, and one bag being selected or not doesn't affect whether or not another bag will be selected. Suppose that 222 bags go through the system, one after the other. What is the probability that both bags are selected for extra screening? Round your answer to two decimal places.

Answers

Probabilities are used to determine the chances of an event.

The probability that the two bags are selected for extra screening is 0.02

The given parameters are:

[tex]n = 2[/tex] --- number of bags

[tex]p = 14\%[/tex] --- the probability that a bag is selected for extra screening

The probability that the two bags are selected for extra screening is:

[tex]P(2) = p^n[/tex]

So, we have:

[tex]P(2) = (14\%)^2[/tex]

Express percentage as decimal

[tex]P(2) = (0.14)^2[/tex]

[tex]P(2) = 0.0196[/tex]

Approximate

[tex]P(2) = 0.02[/tex]

Hence, the required probability is 0.02

Answer:

To distribute means to divide something or give a share or part of something. According to the distributive 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.

The distributive property states that an expression which is given in form of A (B + C) can be solved as A × (B + C) = AB + AC.

What is the distributive property?

Distributive property says that the sum of two or more addends multiplied by a number gives you the same answer as distributing the multiplier, multiplying each addend separately, and adding the products together.

According to the distributive property, multiplying the sum of two or more addends by a number produces the same result as when each addend is multiplied individually by the number and the products are added together.

Example: Find the product using distributive property 6(42+35)

Now, 6(42+35)

= 6×42+6×35

= 252+210

= 462

Hence, the distributive property states that an expression which is given in form of A (B + C) can be solved as A × (B + C) = AB + AC.

–5x - 5y = -10

Answers

Step-by-step explanation:

The usual thing to do is to try to get rid of one variable first. So to get rid of x, we multiply the first equation by 5.

5(x + y) = 2(5)

-5x - 5y = -10

---> 5x + 5y = 10

-5x - 5y = -10

---> 0 = 0

As you can see, everything cancels out. If the statement is true, then it is infinitely many solutions.

After two semesters of course work, a student has completed 32 credit hours of course work with a grade point average of 3.15. What grade point average will the
student need to complete in order to raise their cumulative grade point average to 3.2, if the student is taking 14 credit hours of graded course work this semester
(third semester)?

Answers

Using weighed average, it is found that the student will need a GPA of 3.31.

To find a weighed average, each value is multiplied by it's weight.

For the student's average, we have that:

GPA of 3.15 with a weight of 32.GPA of x with a weight of 14.

We want the mean to be 3.2, thus:

[tex]\frac{3.15(32) + 14x}{32 + 14} = 3.2[/tex]

[tex]3.15(32) + 14x = 46(3.2)[/tex]

[tex]14x = 46(3.2) - 32(3.15)[/tex]

[tex]14x = 46.4[/tex]

[tex]x = \frac{46.4}{14}[/tex]

[tex]x = 3.31[/tex]

The student will need a GPA of 3.31.
