justin did push ups every day this week. he did 8 push ups monday. 14 push ups on tuesday. 18 push ups wednesday. 6 pushups thursday, and 8 push ups friday. find the mean number of pushups.​

Answers

Answer 1

Answer:

9

Step-by-step explanation:

if you list them from least to greatest, it would go: 6, 8, 8, 9, 12, 14, 18

Eliminate it one by one on each side and the middle number is 9

Answer 2

Answer:

The mean number is 10.8

Step-by-step explanation:

Since the mean number is the average of all numbers divided by how many there are, then 8+14+18+6+8=54. 54 divided by 5 equals 10.8.

Suppose you draw two cards from a standard 52-card deck. Find the probability, when both cards are drawn without replacement, that the first card is a spade and the second card has a different suit.

Answers

18.75%
There are 4 suits in a standard deck and each hold 13 cards from ace to king. The probability of drawing a spade will be 25% because there is a 1/4 chance. To first draw a spade and then drawing a card that is not a spade is about 75% so if you multiply 0.25 and 0.75 together you get 0.1875 which equals 18.75%

Step-by-step explanation:

1. A newborn giraffe weighs about 65 kilograms. How much does it weigh in grams?

65 kg = 65*1000 g = 65000 g

2. The average height of a female giraffe is 4.6 meters. What is her height in centimeters?

4.6 m = 4.6*100 cm = 460 cm

3. The capacity of a beaker is 0.1 liter. Convert this to milliliters.

0.1 l = 0.1*1000 ml = 100 ml

4. A pig weighs 9.8 pounds. Convert the pig’s weight to ounces.

9.8 pounds = 9.8*16 ounces = 156.8 ounces

5. A marker is 0.13 meters long. What is the length in millimeters?

Answers

Answer:

A .x+y=150 y=x+80

B. x=35 y=115

x + (x + 80) = 150

2x + 80 = 150

2x = 70

x =35 practicing the guitar

then put x back in to solve for y

C. no because that is a whole 10 minutes more so it would be for 160 minutes of practice instead.

Step-by-step explanation:

this is my first time answering a question so hope it helps :)

Part A:

A pair of linear equations to show the relationship between the number of minutes ;

x=Max practices the guitar

y= the number of minutes he practices the piano

Pair of equation are :

x+y=150

y=x+80

Part B:

The time does Max spend practicing the piano every day:

x=35 y=115 x + (x + 80) = 150 2x + 80 = 150 2x = 70 x =35

Subsitute x back in to solve for y.

x+y=150  

35+y=150

y=115

Part C:

No , it is not possible because that is a whole 10 minutes more so it would be for 160 minutes of practice instead.

c. y=x, y=x^3, y=1/x, y=cos x
d. y=1/x, y=sin x, y=x^2

Answers

The plot of a function f(x) is symmetric across the y-axis if it is even, meaning f(-x) = f(x) for all x in the function's domain.

The answer is then A because

(-x)² = (-1)² x² = x²

|-x| = |-1| |x| = |x|

cos(-x) = cos(x)

The answer is not

• B because sin(-x) = -sin(x) and (-x)³ = (-1)³ x³ = -x³

• C because -xx and again because of x³

• D because 1/(-x) = -1/x and again because of sin(x)

At a local department store, skirts typically cost $15. However, due to a special, the
skirts are reduced to $3. What percent of the original price has the skirts been reduced
to?

Answers

Answer: 20%

Step-by-step explanation:

(part / whole) * 100

(3 / 15) * 100 = 20%

The skirts have been reduced to 20% of their original price.

You are looking for the percentage of the original price that the new price is. This means that you are looking for what percentage of $15 that $3 is:

= New price / Original price x 100%

= 3 / 15 x 100%

= 1/5 x 100%

= 20%

The skirts have therefore been reduced to 20% of their original price.

Juniper drives at a constant speed on the highway towards Exit 34. The graph below shows the distance, in miles, that Juniper is from Exit 34 over time.
——————————

The slope of the graph is
60.

The y-intercept gives the initial distance, in miles, from Exit 34.

The y-intercept of the graph is
3.5.

The slope gives the rate, in miles per hour, at which the distance to Exit 34 changes over time.

Answers

Answer:

Options (2) and (4)

Step-by-step explanation:

Option (1)

The slope of the graph is 60.

From the graph attached,

Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

         = [tex]\frac{-210}{3.5}[/tex]

         = - 60

False.

Option (2)

y-intercept gives the initial distance, in miles from Exit 34.

True.

Option (3)

y-intercept of the graph is 3.5

Since, y-intercept of the graph is 210.

Therefore, Option (3) is False.

Option (4)

Slope gives the rate, in miles per hour, at which the distance to Exit 34 changes over time.

True.

Step-by-step explanation:

Possible rational zeros are of the form ...

  ±{divisor of the constant term}/{divisor of the leading coefficient}

__

1. Rational zeros will be one of ±{1, 2, 3, 6, 9, 18}/{1, 2}, so will be ...

  {±1/2, ±1, ±3/2, ±2, ±3, ±9/2, ±6, ±9, ±18}

__

2. Rational zeros will be one of {±1, ±2, ±3, ±4, ±6, ±8, ±12 ±24}.

__

3. The pairs of coefficients suggest factoring by pairs:

  f(x) = (2x^3 +2x^2) -(8x +8) = 2x^2(x +1) -8(x +1) = 2(x^2 -4)(x +1)

  f(x) = 2(x -2)(x +2)(x +1)

Zeros of f(x) are 2, -2, -1, values of x that make the factors zero.

__

4. The sum of coefficients is zero, so x=1 is a zero. Factoring that out by any of several means, you find ...

  f(x) = (x -1)(x^2 +2x -8)

The quadratic is factored by looking for factors of -8 that have a sum of 2. (4 and -2 are those)

  f(x) = (x -1)(x +4)(x -2)

Zeros of f(x) are 1, -4, 2.
