Answer: 5

Explanation:

Cube root (125) = Cube root(5^3) = 5

Answer: 5

Step-by-step explanation: 5 x 5 x 5 = 125 and since your finding the cubed root of 125, there are supposed to be 3 numbers you multiply that are the same. This is why the answer is 5. Plus, Roots are the inverse operation of exponents.

A recent survey of people who eat salad suggest that 78% like tomatoes on their salad, 49% like cheese on their salad, and 36% like both tomatoes and cheese on their salad. Suppose a person who eats salad is selected at random, and find they like cheese on their salad. What is the probability that the person also likes tomatoes on their salad?

0.29
0.46
0.49
0.73

Answers

Answer:

D) 0.73

Step-by-step explanation:

If we take the number of people liking cheese on their salad and divide it by the people who like both we get our result.

36%/49%

=

.36/.49

=

.73 or D

The conditional probability that the person also likes tomatoes on their salad is of 0.73.

What is Conditional Probability?

Conditional probability is the probability of one event happening, considering a previous event. The formula 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 problem, the events are given as follows:

Event A: Person likes cheese.Event B: Person likes tomatoes.

Hence, the probabilities are given by:

[tex]P(A) = 0.49, P(A \cap B) = 0.36[/tex].

The conditional probability is given by:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.36}{0.49} = 0.73[/tex]

What is the image of ( 3 , − 5 ) (3,−5) after a dilation by a scale factor of 5 5 centered at the origin?

Answers

Answer:

The coordinates of the image will be: (15, -25)

Step-by-step explanation:

Given the point

(3,−5)The scale factor 5.

A scale factor of 5 means that the new shape is five times the size of the original.

The coordinates of the image of (3,−5) after dilation by a scale factor of 5 centered at the origin can be obtained by multiplying the original coordinates of the object point by 5.

i.e.

(x, y) → (5x, 5y)

(3, -5) → (5×3, 5×(-5)) = (15, -25)

Therefore, the coordinates of the image will be: (15, -25)

Exponential Decay Function

The exponential function is used to model natural decaying processes, where the change is proportional to the actual quantity.

An exponential decaying function is expressed as:

[tex]C(t)=C_o\cdot(1-r)^t[/tex]

Where:

C(t) is the actual value of the function at time t

Co is the initial value of C at t=0

r is the decaying rate, expressed in decimal

The element has an initial mass of Mo=970 grams, the decaying rate is r=27.7% = 0.277 per minute.

The equation of the model is:

[tex]M(t)=M_o\cdot(1-r)^t[/tex]

[tex]M(t)=970\cdot(1-0.277)^t[/tex]

Operating:

[tex]M(t)=970\cdot 0.723^t[/tex]

After t=13 minutes the remaining mass is:

[tex]M(13)=970\cdot 0.723^{13}[/tex]

Calculating:

M(13)=14.3 gram

Answers

Answer:

a. 6

b. 12

c. [tex] y = 6x + 12 [/tex]

Step-by-step explanation:

a. Using two pairs of values given, (0, 12) and (1, 18)

Rate/slope = [tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{18 - 12}{1 - 0} = \frac{6}{1} = 6 [/tex]

Unit rate/slope (m) = 6

b. The starting value is the y-intercept (b). It is the value of of y when x = 0.

From the table, when x = 0, y = 12.

Therefore the starting value (b) would be 12.

c. The equation can be written in slope-intercept form, [tex] y = mx + b [/tex], where,

m = slope/rate = 6

b = starting value/intercept = 12.

Plug in the values into the equation

The equation would be:

✅[tex] y = 6x + 12 [/tex]

Question: Write a loop that inputs words until the user enters STOP.

Answer:

count = 0

word = input("User Input: ")

while word!="STOP":

    count = count+1

    print("You entered: "+str(word))

    word = input("User Input: ")

print("All done. "+str(count)+" words entered")

Step-by-step explanation:

This line initializes counter variable count to 0

count = 0

This line prompts user for input

word = input("User Input: ")

The following iteration is executed until user enters STOP

while word!="STOP":

This increments counter variable by 1

    count = count+1

This prints the word entered by the user

    print("You entered: "+str(word))

This line prompts user for another input

    word = input("User Input: ")

This prints the number of input by the user

print("All done. "+str(count)+" words entered")

Answer:

c = 0

word = input("Enter a word: ")

while word!="STOP":

  c = c+1

  print("#" + str(c) + ": You entered "+str(word))

  word = input("Please enter the next word: ")

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The number of songs is 19.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of games downloaded = g

Number of songs downloaded = g + 8

Total number of songs and games downloaded = 30

Now,

g + (g + 8) = 30

g + g + 8 = 30

2g + 8 = 30

Subtract 8 on both sides.

2g = 30 - 8

2g = 22

Divide 2 on both sides.

g = 11

The number of games = 11

The number of songs = 11 + 8 = 19

Thus,

The number of games is 11.

The number of songs is 19.

Answer:

Step-by-step explanation:

The y-axis corresponds to the line x=0. Any point on the y-axis will have an x-coordinate of 0.

If (a, b) is on the y-axis, then a = 0.

If the intersection point is (0, 0), then b=0. Otherwise, b is not 0.

Answer:

-9/22t

Step-by-step explanation:

since the denominators (22) and the variable are the same, you can pretend as if you are only solving -4 - 5

-4 minus 5 is making the number go farther left from the zero on the number line

so the number itself is getting bigger, but the sign will stay negative

if you move five left from -4 on a number line you get -9

so now you can add the denominator to your answer: -9/22 t

Graph the following direct proportions: y=-2.5x
If possible please explain how to do this so I won’t have to ask future questions :)

Answers

since the equation doesn’t have a constant term following the slope then it goes through the origin (0,0)

so start from the origin and go down 2.5 and over to the right 1 and keep repeating that pattern

then to make the left end of the line, go 2.5 up and 1 left

this will result in a line going downwards at a slope of 2.5 (aka making a y = -2.5x line)
