Can someone please work out both problems, I need help with my math hw due in 4 hours

Answer:

C

Step-by-step explanation:

What I think

Answer: A= 2.5

              B= 12.9

              C= 12

              D= 3 (the 3 is a whole number not added to the fraction.)

              E= 4

Answer:

0.4198 = 41.98% probability that he or she has a basic model

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Extended warranty

Event B: Basic model

Probability of extended warranty:

34% of 50%(basic model)

47% of 100 - 50 = 50%(deluxe model). So

[tex]P(A) = 0.34*0.5 + 0.47*0.5 = 0.405[/tex]

Intersection of events A and B:

34% of 50%(basic model with extended warranty). So

[tex]P(A \cap B) = 0.34*0.5 = 0.17[/tex]

How likely is it that he or she has a basic model

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.17}{0.405} = 0.4198[/tex]

0.4198 = 41.98% probability that he or she has a basic model

Answer:

32.4%

Step-by-step explanation:

[tex]\frac{90x36}{100}[/tex]=[tex]\frac{3240}{100}[/tex]=32.4%

Answer:

I would say that this is 40 packs of mint flavored gum (sorry if this is wrong)

Step-by-step explanation:

Since there are 100 packs of gum, the 40% just turns into 40

Answer:

Answer:

110

Step-by-step explanation:

3x+5+2x=180

Step 1: Simplify both sides of the equation.

3x+5+2x=180

(3x+2x)+(5)=180(Combine Like Terms)

5x+5=180

5x+5=180

Step 2: Subtract 5 from both sides.

5x+5−5=180−5

5x=175

Step 3: Divide both sides by 5.

x=35

35*3+5=110

Answer:

B.9x

Step-by-step explanation:

A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.

Answer:

c.

Step-by-step explanation:

The pattern is supposed to be -4.

Gianna has 76 stamps left after 6 packages and pattern of decreasing stamps can be calculated as 100, 96, 92, 88, 84, 80, 76. Hence option c is correct

Gianna uses 100 stamps each day for her business. If she begins each day with 100 stamps, and after each package that is shipped has 4 less stamps,

In mathematics it deals with numbers of operations according to the statements.

As per question, after each package that is shipped has 4 less stamps.
Now,  for nth term of an arithmetic progression.
nth term = a + nd
Here, we have a = 100, d = -4 and  n = 6
So after 6th package shipped the number of stamps left.
= 100 - 6 x 4
= 76
And pattern of decreasing stamps can be calculated as 100, 96,92,88,84,80,76.

Thus, Gianna has 76 stamps left after 6 packages and pattern of decreasing stamps can be calculated as 100, 96,92,88,84,80,76.

Step-by-step explanation:

3x4 is 12 and then you subtract them from each 9ther

Answer:

The rate of the train on level ground is 75 mph, and the rate of the train in the mountains is 30 mph like you mentioned. If you were asking for the time it takes for the train to travel 120 miles in that speed in the mountain, then it would be 4 hours.

Answer:

Dakota must put 50 grams of clay in each pot to be able to divide the clay into 8 equal parts.

Step-by-step explanation:

Given that Dakota has 4/10 kg of clay and I divided the clay to make eight equal pots, to determine how many grams of clay are in each pot the following calculation must be performed:

4/10 kg = 0.4 kg = 400 grams

400/8 = X

50 = X

Thus, Dakota must put 50 grams of clay in each pot to be able to divide the clay into 8 equal parts.

Edge 2021

Answer:  the answer is 2.5

Step-by-step explanation:

Answer:

w= 5/2 inches or 2 1/2 inches

Step-by-step explanation:

area = length × width (w)

45/4 = 9/2 × w

45/4 =9w/2

45×2 = 9w×4

90 = 9w×4

9w= 90/4= 45/2

w= 45/2 × 1/9

w= 5/2 inches or 2 1/2 inches

Answer:

Option C - 1/81

Step-by-step explanation:

9^(-2) = 1/(9^2) [ Because a^(-m) = 1/(a^m) ]

so, 1/(9²) = 1/81.

Hope this helps you.

The correct expression which is equivalent to 9⁻² is,

⇒ 1 / 81

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ 9⁻²
