The length of the other leg of the right triangle will be 13.86 cm.

The complete question is given below.

The triangle BCD is a right triangle. The length of the hypotenuse is 19 centimeters. The length of one of the legs is 13 centimeters.

What is the length of the other leg?

<h3>What is a Pythagoras theorem?</h3>

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The Pythagoras theorem formula is given as

H² = P² + B²

Let the unknown sides be x. Then we have,

19² = 13² + x²

361 = 169 + x²

x² = 361 – 169

x² = 192

x = 13.856 ≈ 13.86 cm

More about the Pythagoras theorem link is given below.

Justin buys 12 pencils for $0.56. He pays with a $10 bill. How much charge will he recieve?

Andreyy89

I don't imagine you could divide with this since the answer would lead to 0.04 but if so i'm an idiot.

The way i would do it is 12 x 0.56 which makes 6.72. (it just makes sense?)

So for the 0.04 he would get back 9.96

The 6.72 he would get back 3.28

Sorry i considered the possibilities.

To determine the ________ of an event, you can use the formula P(E) = n(E)/n(S), where n(E) is the number of outcomes in the eve

Semenov [28]

Answer:

Probability

Step-by-step explanation:

Probability of an event is how likely that event is to happen. And it is denoted by letter P and calculated by the formula below:

P(E) = number of possible outcome/number of the total event sample

P(E) = n(E) / n(S)

Pennies made before 1983 are 97% copper and 3% zinc, whereas pennies made after 1983 are 3% copper and 97% zinc. listed belo

The table in the attached figure

Pennies made before 1983
Part a) find the mean
we have
[3.1047,3.1082, 3.1582, 3.0776, 3.1276, 3.1035]
Mean 1=[3.1047+3.1082 + 3.1582 + 3.0776 + 3.1276 + 3.1035]/6
Mean 1=3.1133 grams

the answer part a) is
The mean weight of the pennies made before 1983 is 3.1133 grams.

Part b)
to find the Median, place the numbers in value order and find the middle.
[3.1047,3.1082, 3.1582, 3.0776, 3.1276, 3.1035]
[3.0776, 3.1035, 3.1047,3.1082, 3.1276, 3.1582]
(3.1047+3.1082)/2=3.10645 grams

the answer part b) is
The median weight of the pennies made before 1983 is 3.10645 grams.

Pennies made after 1983
Part c) find the mean
we have
[2.4842, 2.4828, 2.5024, 2.4997, 2.4907, 2.4956]
Mean 2=[2.4842 + 2.4828 + 2.5024 + 2.4997 + 2.4907 + 2.4956]/6
Mean 2=2.4926 grams

the answer part c) is
The mean weight of the pennies made after 1983 is 2.4926 grams.

Part d)
to find the Median, place the numbers in value order and find the middle
[2.4842, 2.4828, 2.5024, 2.4997, 2.4907, 2.4956]
[2.4828, 2.4842, 2.4907, 2.4956, 2.4997, 2.5024]
[2.4907 +2.4956]/2=2.49315

the answer part d) is
The median weight of the pennies made after 1983 is 2.49315 grams.

Part e) compare the means
Find the percentage difference
 the percentage difference is the difference between the new value and the old value, divided by the old value
so
new value=2.4926 grams
old value=3.1133 grams
[3.1133-2.4926]/3.1133------> 0.20-----> 20%
that means
the difference in the means is considerable to be greater than 5%
