divide 3000 by 10 to get a tenth of 3000

If 3,000 is divided into ten equal parts, then one of those parts would be 300. You can also use the equation $\frac{1}{10} * 3,000 = \frac{3,000}{10}$ .

$\frac{1}{10}$ of 3,000 is 300.

What is the least common denominator for the fractions1/6and 3/4 ?

melomori [17]

A. 12; Least common denominator is the least multiple that the denominator have together. So you multiply the denominators until you get the first number they both have in common.
6*1 = 6
6*2 =12

4*1 =4
4*2 =8
4*3 = 12

Since the first number they both have in common is 12, the least common denominator is 12

Left on together, the cold and hot water faucets of a certain bathtub take 8 minutes to fill the tub. If it takes the cold wate

MArishka [77]

Cf=cold faucet rate
hf=hot faucet rate

cf*18min=1 tub
(cf+hf)*8min=1 tub
cf+hf=1tub/8min
cf=1tub/18min
hf=(1/8-1/18)tubs per minute
hf=5/72

It takes 14.4 minutes.

Answer:

The measure of reference angle is $30^{\circ}$ .
$\cos \theta=\frac{\sqrt{3}}{2}$

Step-by-step explanation:

Converting $\theta$ to degrees,

$\theta=\left(\frac{11\pi}{6} \right) \left(\frac{180}{\pi} \right)=330^{\circ}$

This means $\theta$ lies in Quadrant 4, and thus its reference angle is $360^{\circ}-330^{\circ}=\boxed{30^{\circ}}$

Since $\theta$ lies in the fourth quadrant, $\sin \theta$ and $\tan \theta$ are negative.

Since $\theta$ lies in the fourth quadrant, $\cos \theta$ is positive, and is equal to $\cos (30^{\circ})=\boxed{\frac{\sqrt{3}}{2}}$

It is estimated that one third of the general population has blood type A A sample of six people is selected at random. What is

Feliz [49]

Answer: 0.2195

Step-by-step explanation:

Binomial distribution formula :-

$P(x)=^nC_xp^x(1-p)^{n-x}$ , where P(x) is the probability of x successes in the n independent trials of the experiment and p is the probability of success.

Given : The probability of that the general population has blood type A = $\dfrac{1}{3}$

Sample size : n=6

Now, the probability that exactly three of them have blood type A is given by :-

$P(3)=^6C_3(\dfrac{1}{3})^3(1-\dfrac{1}{3})^{6-3}\\\\=\dfrac{6!}{3!3!}(\dfrac{1}{3})^3(\dfrac{2}{3})^{3}\\\\=0.219478737997\approx0.2195$

Therefore, the probability that exactly three of them have blood type A = 0.2195
