The weight of an object on Mars m is 40% of its weight on Earth w. Write a function rule for the situation. Then find the weight

Marrrta [24]

Answer: The weight of space probe on Mars is 6 lb.

Write a function rule for each situation. Then use your function as indicated. The force of gravity is less on Mars than it is on Earth. As a result, the weight of an object on Mars m is 40% of its weight on Earth w. Use your function to find the weight on Mars of a space probe that weighs 15 lb on Earth.

m is weight on Mars

w is weight on Earth

m is 40% of w

f(w) = m = (40/100)w

The weight of space probe is 15 lb on Earth

substituting w = 15 in the function we get,

f(15) = m = (40/100)15

= 6

ANSWER: The weight of space probe on Mars is 6 lb.

Step-by-step explanation:

Answer:

Hence, the answer is 40 pounds.

Step-by-step explanation:

An object that weighs 50 pounds on mars weighs 150 pounds on earth.

Let the object weighing 120 pounds on Earth, weighs x pounds on Mars.

We can solve this equation as :

=>

x = 40 pounds

Hence, the answer is 40 pounds.

Or we can also solve this as :

150 pounds on Earth weighs 50 pounds on Mars.

1 pound weighs = pounds on Mars

And 120 pounds will weigh = pounds on Mars.

Landon babysits and works part time. He babysat for 3 hours and worked at the water park for 10 hours and made 109$. Next week h

vovangra [49]

Answer:

$10.5 and $7.75

Step-by-step explanation:

Let Landon's hourly rate at babysitting job be $x$ and at water park be $y$

now, for the first week Landon babysat for 3 hours and worked at the water park for 10 hours and made 109$.

⇒ $3x + 10y = 109$ ....(1)

Next week Landon babysat for 8 hours and worked at the water park for 12 hours and made 177$.

⇒ $8x + 12y = 177$ ....(2)

From equation (2) we get

$y = \frac{177 - 8x}{12}$ ....(3)

Substituting value of $x$ from equation (3) to equation (1) we get

$x = 10.5$

Using value of x in equation (1) we get

$y = 7.75$

Hence hourly rate for Landon for babysitting job is $10.5 and for water park job is $7.75

10. A random sample of 10 fibers is taken from a collection of 92 fibers that consists of 43 fibers of polymer A, 17 fibers of p

vazorg [7]

Answer:

0.1150 = 11.50% probability that the sample does not contain any fibers of polymer B

Step-by-step explanation:

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this question:

Fibers are chosen without replacement, which means that we use the hypergeometric distribution.

92 fibers means that $N = 92$

Sample of 10 means that $n = 10$

No polymeter B which means that $x = 0$

17 fibers of polymeter B which means that $k = 17$

a. What is the probability that the sample does not contain any fibers of polymer B

This is P(X = 0).

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

$P(X = 0) = h(0,92,10,17) = \frac{C_{17,0}*C_{75,10}}{C_{92,10}} = 0.1150$

0.1150 = 11.50% probability that the sample does not contain any fibers of polymer B
