Answer:

The answer is 907.5.

Step-by-step explanation:

The tenths place is the number just after the decimal. To round, we need to look at the number just to the right of the digit we need to round to. In this case, that number is 5. Now, if the digit to the right is anywhere from 1-4, we round down, by which I mean we keep the number the same. But if it is from 5-9, we round up. Therefore, we round up in this case, getting 907.5.

Answer:

(a) 51%

(b) 41%

Step-by-step explanation:

We can simplify this problem down by realizing that the amount of girls over 200 will get us our percentage as a decimal.

Looking at this table, we can see that $30+72=102$ girls were asked. So, $102\div200=0.51$ , and $0.51\cdot100=51$ .

We can also see that $30+52=82$ people preferred video games, so $82\div200=0.41$ , and $0.41\cdot100=41$ .

Hope this helped!

Answers;<br> A) 135 degree’s<br> B) 30 Degree’s<br> C) 180 or 0 Degree’s<br> D) 90 Degree’s

Vladimir [108]

Answer:

C). 0 degrees

Step-by-step explanation:

The given equation is:

-4 + 6 sinx = -4 + 4 sinx

adding 4 on both sides:

4 - 4 + 6 sinx = 4 - 4 + 4 sinx

6sinx = 4sinx

dividing by 2 on both sides, we get:

6sinx/2 = 4sinx/2

3 sinx = 2 sinx

subtracting 2 sinx from both sides we get:

sin x = 0

x = sin⁻¹ (0)

x = 0 degrees

There are 30 balls numbered 1-30 in a bag. One is randomly selected 12 times. What is the probability of getting a prime number

Sliva [168]

Answer: The probability of getting a prime number exactly five times = 0.1908

Step-by-step explanation:

Prime numbers from 1 to 30 are 2,3,5,7,11, 13, 17, 19, 23, 29.

The probability of getting a prime number p= $\dfrac{10}{30}=\dfrac13$

Number of trials n = 12

Binomial probability formula:

$P(X=x) = \ ^nC_x p^x(1-p)^{n-x}$

, where x= number of successes

n= number of trials.

x = Number of successes

p= probability of getting one success.

The probability of getting a prime number exactly five times:

$P(X=5)=\ ^{12}C_5(\frac13)^5(1-\frac13)^{7}$

$=\frac{12!}{5!7!}(\frac1{243})(\frac{128}{2187})\\\\=0.1908$

Hence, the probability of getting a prime number exactly five times = 0.1908
