Karen spends 450 on monthly bills.of this total amount,12% is for phone service,1/10 is internet service,2/9 is for utilities.id the rest of the amount is for food ,how much does Karen have for

Answers

The complete question is:
 how much does Karen have for food?

 For this case, we have that the full amount of money is:
 12/100 + 1/10 + 2/9 + x = 1
 Where,
 x: fraction of money for food
 Clearing x we have:
 x = 1 - (12/100 + 1/10 + 2/9)
 Rewriting:
 x = 251/450
 Thus, the amount of money for food is:
 450 * x = 450 * (251/450) = 251
 Answer:
 Karen has for food about:

The table shows the results of spinning a spinner several times. (Don’t mind my answer)

Answers

The answer is 1/4. To find this, add all the frequencies together, then you get 12. Then add B and C together to get 4. Divide 12 by 4 and get 1/4.

The experimental probability of spinning a B or a C is [tex]\( \frac{1}{4} \)[/tex].

To find the experimental probability of spinning a B or a C, we need to sum up the frequencies of outcomes B and C and then divide that by the total number of spins.

Given frequencies:

Outcome A: 3

Outcome B: 2

Outcome C: 1

Outcome D: 4

Outcome E: 2

Total frequency of B and C: 2 (from outcome B) + 1 (from outcome C) = 3

Total number of spins: Sum of all frequencies = 3 + 2 + 1 + 4 + 2 = 12

Experimental probability of spinning a B or a C: [tex]\(\frac{\text{Total frequency of B and C}}{\text{Total number of spins}} = \frac{3}{12} = \frac{1}{4}\)[/tex]

So, the experimental probability of spinning a B or a C is [tex]\(\frac{1}{4}\)[/tex].

A new patio will be an irregular hexagon. The patio will have two long parallel sides and an area of 360 square feet. The area of a geometrically similar patio is 250 square feet, and it’s long parallel sides are 12.5 feet apart. What is the corresponding distance on the new patio

Answers

The length of the new patio will be evaluated as follows:
The area scale factor=(area of new patio)/(area of original patio)
=360/250
=36/25
but
Linear scale factor=√(area scale factor)
Linear scale factor=√(36/25)=6/5
thus the length of the patio will be:
length=(linear scale factor)*(length of the original patio)
=6/5×12.5=15 ft

When Sally went bowling her scores were 108, 72, and 95. If she bowls a 4th game, what will her score need to be to give her an average of 91?

Answers

x= score of 4th game

Add the 4 scores, divide by 4 and set it equal to 91


(108 + 72 + 95 + x)/ 4= 91
multiply both sides by 4 to eliminate fraction

108 + 72 + 95 + x= 364
275 + x= 364

subtract both sides by 275
x= 89


ANSWER: The scored needed for the fourth game is 89.

Hope this helps! :)

To achieve an average score of 91, Sally needs to bowl an 89 in her fourth game, calculated by subtracting her current total score of 275 from the desired total of 364 points.

To calculate the score Sally needs in her fourth game to achieve an average of 91, we first need to determine the total points she needs after four games. We can calculate the required total points by multiplying the desired average score by the number of games:

91 × 4 = 364 total points

Next, we add up the scores from Sally's first three games:

108 + 72 + 95 = 275 points

Finally, we subtract the sum of her first three games from the total required points to find the score Sally needs in her fourth game:

364 - 275 = 89 points

Therefore, Sally needs to bowl a score of 89 in her fourth game to achieve an average of 91.

Sam intends to roll a six sided cube 100 times. What is the probability model he can use to predict whether or not each roll will give a result that is not a prime number?

Answers

It’s 0.5 probability chance because it is still the same cube being used for the probability of it landing on a prime number

The outcomes of rolling fair six sided die is [tex] \{1,2,3,4,5,6\} [/tex]. The prime numbers in the above outcomes are [tex] \{2,3,5\} [/tex]. The probability of not rolling a prime number is [tex] p=\frac{3}{6}= 0.5 [/tex].

Each trial is independent.

In the given experiment of 100 trials, the binomial probability model can be used to predict the number of occurrence of non-prime numbers (X). The probability mass function is

[tex] P(X=x)=C(100,x)p^x(1-p)^{100-x},x=0,1,2,3,...,100 [/tex]. Since [tex] p=0.5,1-p=0.5 [/tex]

[tex] P(X=x)=C(100,x)0.5^x(0.5)^{100-x},x=0,1,2,3,...,100 \\
P(X=x)=C(100,x)(0.5)^{100},x=0,1,2,3,...,100 [/tex]

Helpppp plzzz Maddie is packing for a trip. in her closet,there are 3 red, 4 black, 2 green, and 2 yellow blouses. She randomly selects 2 blouses. Find each probability. 1. P(black and yellow) 2. P(green and green

Answers

Final answer:

Calculate the probabilities of selecting specific pairs of blouses from Maddie's closet with different colors.

Explanation:

1. P(black and yellow):

Number of ways to select 1 black blouse out of 4 black blouses = 4Number of ways to select 1 yellow blouse out of 2 yellow blouses = 2Total number of ways to select 2 blouses out of 11 blouses = 11C2 = 55

Therefore, P(black and yellow) = (4/55) * (2/11) = 8/605

2. P(green and green):

Number of ways to select 2 green blouses out of 2 green blouses = 1Total number of ways to select 2 blouses out of 11 blouses = 11C2 = 55

Therefore, P(green and green) = (1/55) * (1/11) = 1/605

which expression gives the length of pq in the triangle shown below?

Answers

For this case what we should do is use the Pythagorean theorem.
 We have then:
 PQ ^ 2 = 15 ^ 2 + 19 ^ 2
 Clearing we have:
 PQ = root (15 ^ 2 + 19 ^ 2)
 Answer:
 
The expression used to find PQ is given by:
 
PQ = root (15 ^ 2 + 19 ^ 2)
 
option C
We have to use the Pythagorean theorem.
 So it will be:
 PQ ^ 2 = 15 ^ 2 + 19 ^ 2
 PQ = root (15 ^ 2 + 19 ^ 2)
 So the expression used to find PQ is given by:
 PQ = root (15 ^ 2 + 19 ^ 2)
 

So the answer would be letter C.

Which system of equation can represent the equation?

Answers

Answer:

         log(x+3)
y₁ =  --------------
            log(4)

         log(2 + x)
y₂ = ----------------
             log(2)

Explanation:

1) Here you must use the property named change of base of the logarithm.

That rule is:

[tex]log_{a}b= \frac{log_c{b}}{log_ca} [/tex]

2) Changing to base 10 that is:

[tex]log_{b}a= \frac{loga}{logb} [/tex]

3) Using it with the given equation, you get:

[tex]log_4(x+3)= \frac{log_(x+3)}{log(4)} log_2(2+x)= \frac{log(2+x)}{log(2)}[/tex]

4) Now, to set your system you can make the left side of the equation equal to y₁ and the right side equal to y₂

         log(x+3)
y₁ =  -------------
           log(4)

         log(2 + x)
y₂ = ---------------
            log(2)

And that is your system which is the first choice of the list.

How many cubic centimeters of water can this paper cone cup hold?

Answers

Final answer:

To determine the number of cubic centimeters of water that the paper cone cup can hold, calculate the volume using the formula for the volume of a cone, and then convert it to cubic centimeters.

Explanation:

To calculate the number of cubic centimeters of water the paper cone cup can hold, we need to first determine its volume. The volume of a cone can be calculated using the formula V = (1/3) π r² h, where V is the volume, π is the mathematical constant pi, r is the radius of the base of the cone, and h is the height of the cone.

Once we have the volume of the cone, we can convert it to cubic centimeters since the dimensions given are in centimeters. Finally, we can determine the number of cubic centimeters of water the paper cone cup can hold.

For example, if the cone has a radius of 5 cm and a height of 10 cm, the volume would be:

V = (1/3) π (5 cm)² (10 cm)

V = (1/3) π (25 cm²) (10 cm)

V = (1/3) π (250 cm³)

V ≈ 261.79 cm³

Therefore, the paper cone cup can hold approximately 261.79 cubic centimeters of water.
