Does 22km 22m = 2222m

1 answer:

8 0

Based on the given numbers above, we must first remember that in every one kilometer is equal to one thousand meters (1000m). So if we convert 22 kilometers to meters, we get 22,000 meters. Add this up with 22 meters, we get 22,022 meters. Therefore, the answer for the given above would be FALSE. Hope this answer helps.

Tara has two bags of marbles the first bag contains 8 red marbles four blue marbles three green marbles the second bag contains

Lesechka [4]

Answer:

2/27

Explanation:

The two events, drawing a blue marble out of each bag, are independent. This means to find the probability of both occurring, we multiply them.

In the first bag, there are 5 blue marbles out of 15 total. This makes the probability 5/15, or 1/3.

In the second bag, there are 2 blue marbles out of 9 total. This makes the probability 2/9.

Together, the probability of both events happening are:

1/3(2/9) = 2/27

PLEASE HELP I DONT KNOW HOW TO SOLVE THIS :((

ANEK [815]

Answer:

$\displaystyle \angle A=30^\circ$

Step-by-step explanation:

We are given that in Circle O, Arc BAC measures 300°.

Recall that arc lengths will always total 360°. Therefore:

$\stackrel{\frown}{BAC}+\stackrel{\frown}{CB}=360^\circ$

By substitution:

$300+\stackrel{\frown}{CB}=360$

Thus:

$\stackrel{\frown}{CB}=60^\circ$

∠A intercepts Arc CB. Since it is an inscribed angle, it will be half of its intercepted arc. In other words:

$\angle A=\displaystyle \frac{1}{2}\stackrel{\frown}{CB}$

Therefore:

$\displaystyle \angle A=\frac{1}{2}(60)=30^\circ$

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

weqwewe [10]

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%
