Lola has a rectangle piece of cardboard. the lenght of the cardboard is 14 inches. the width of the cardboard is half of its len
Vlad1618 [11]
Calculate the width
14:2=7
having given that the lenght is 14 in her slices too it means that she cuts it only in one direction so the width is
7:9=0.77777 (seven in period)

so she is pretty inacurate

Julia enjoys shooting paper balls into the wastebasket across her office. She misses the first shot 50% of the time. When she mi
Marianna [84]

Answer:

a) Probability that Julia misses two shots in a row = \frac{1}{2}\frac{1}{5} =\frac{1}{10}

b) We can use the complement rule on this case. Let X the number of shoots successful, we want this probability:

P(X \geq 1)

And using the complement rule we have this:

P(X \geq 1) = 1-P(X

And P(X=0) correspond to the probability that Julia misses two shots in a row founded on part A so then we have:

P(X\geq 1) = 1- \frac{1}{10}= \frac{9}{10}

Step-by-step explanation:

Part a

For this case we know that Julia enjoys shooting paper balls into the basket across her office.

She misses the first shot 50% of the time.

Probability that Julia misses the first shot = \frac{1}{2}

When she misses on the first shot, she misses the second shot 20% of the time.

Probability that Julia misses the second shot = \frac{1}{5}

For this case we need to find the probability of missing two shots in a row

So we can multiple the two probabilities like this

Probability that Julia misses two shots in a row = \frac{1}{2}\frac{1}{5} =\frac{1}{10}

Part b

For this case we want probability of making at least one successful throw

And we can use the complement rule on this case. Let X the number of shoots successful, we want this probability:

P(X \geq 1)

And using the complement rule we have this:

P(X \geq 1) = 1-P(X

And P(X=0) correspond to the probability that Julia misses two shots in a row founded on part A so then we have:

P(X\geq 1) = 1- \frac{1}{10}= \frac{9}{10}

Michelle and her brothers Sam and Dean are saving money over summer break each week Michelle saves three times as much as Sam Sa
Triss [41]
I believe you want to know how much each of them SAVED.

Let the amount saved by Michelle be x, the amount saved by Sam be y and the amount saved by Dean be z.

From the givens:
x = 3y (Michelle saves 3 times as much as Sam).......eq1
y = 2+z (Sam saves 2$ more than Dean)
z=y-2.........eq 2
x+y+z = 240 (total amount)......eq 3

substitute by equation 1 in 3:
3y+y+z=240
4y+z=240......eq 4

substitute by 2 in 4:
4y+y-2=240
5y=242
y= 48.4$

from 1:
x=3y
x=145.2$

from 2:
z=y-2
z=46.4$
