Use trigonometric ratios.
Use angle(19)
Adjacent side of angle measure 19 is X
The hypotenuse is 21.
Use the cosine
Cos(19)=x/21

Plug in calculator
(21)cos(19)=19.85

Round to the nearest tenth. Which means the 8 rounds up to 9.

1. Suppose you take a coin and flip it 4 times in a row. After each flip you record whether the coin landed heads or tails. What
bekas [8.4K]

Answer:

25%

Step-by-step explanation:

Great question, since a regular coin has two sides one heads and one tails. That gives us a 50% probability of it landing on either side of the coin. Since we would like to know the probability of getting 2 heads in a row, we would need to multiply the probability of the first toss landing on heads with the second toss landing on heads, like so...

\frac{1}{2} *\frac{1}{2} =\frac{1}{4}

So we can see that the probability of us getting two heads in a row is that of \frac{1}{4}[/tex] or 25%.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Christine has $875.83 In her savings account the account pays 9% compounded monthly. Christine does not make any deposits or wit
Karolina [17]

Answer: the account earns interest of $40.16

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1+r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = 875.83

r = 9% = 9/100 = 0.09

n = 12 because it was compounded 12 times in a year.

t = 6 months = 6/12 = 0.5 year

Therefore,.

A = 875.83(1+0.09/12)^0.5 × 12

A = 875.83(1+0.0075)^6

A = 875.83(1.0075)^6

A = 915.99

The interest that she earns is

915.99 - 875.83 = $40.16

guajiro [1.7K]

Answer:

3.25 cm is the answer to 3\frac{1}{4} of a cm.

Step-by-step explanation:

Given:

3\frac{1}{4} of a cm.

Solution:

Type I:

First we will see what is  \frac{1}{4}  

3\frac{1}{4}=0.25

i.e \frac{1}{4}  And  0.25 is SAME.

Now,

3\frac{1}{4}= 3\ and\ 0.25=3+0.25=3.25\ cm

Type II:

3\frac{1}{4}=\frac{4\times 3 + 1}{4}\\3\frac{1}{4}\\=\frac{12+1}{4}\\=\frac{13}{4}\\=3.25\ cm
