Find the value of the x in the equation 4(6x-9. 5)=46.

Alborosie

Following are the calculation to<u> find the value of x</u>:

Given:

$\to 4(6x-9. 5)=46\\$

To find:

x=?

Solution:

$\to 4(6x-9. 5)=46\\\\\to 24x- 38.0=46\\\\\to 24x =46-38\\\\\to 24x= 8\\\\\to x= \frac{8}{24}\\\\\to x= \frac{1}{3}\\\\$

Therefore, the final answer is " $\bold{\frac{1}{3}}$ ".

Luden [163]

Step-by-step explanation:

let the first number be x

let the second number be y

½ of the first number= ½x

Double the second; 2*y=2y

the sum... that is ½x+2y=14

every fourth visitor to a museum gets a free bumper sticker every tent visitor to the museum gets a free keychain which visitor

ioda

The 20th visitor will be the first to get both the key chain and the bumper sticker, I found this out by finding the least common multiple, or LCM, you do this by writing out the multiples of both 4 and 10, 4 8 12 16 20..... and 10 20 30... then you find the smallest number that both 4 and 10 have in common. I hope this helps, sorry if it doesn't.

A basketball player makes 70% of the free throws he shoots. Suppose that he tries 15 free throws.

Volgvan

Answer:

a.) .95

b.) The expected number of baskets is 10.50.

c.) 1.7748

Step-by-step explanation:

a.) This is a binomial distribution as there are two possibilities: makes a free throw or doesn't. This means that you can use the binomial function on a calculator to figure out the answer. Use the binomial CDF function on a calculator and the number of trials=15, probability of success=.7, lower bound=0, upper bound=7. Once you have evaluated the answer, .0500, it will need to be subtracted from1, as you want everything not included in this section. The answer to part a is thus 1-.0500=.95.

b.) The expected value is calculated by taking the total number of shots and multiplying it by the probability of making the shot: 15×.7=10.5 shots.

c.) The standard deviation of a binomial distribution can be calculated by the formula $\sqrt{(sample size)(probability)(1-probability)}$ . Plugging in the numbers you get $\sqrt{(15)(.7)(.3)}$ =1.7748.
