<em>Multiply 5/6 by 3/10 (to do this,</em><em> multiply the numerator by the numerator </em><em>and the </em><em>denominator by the denominator).</em>

<em>Perform the</em><em> multiplications </em><em>in the </em><em>previous fraction.</em>

<em>Reduce the fraction </em><em>15/60</em><em> to its</em><em> lowest expression by extracting</em><em> and canceling 15.</em>

Answer:

$\frac{1}{4}$

Step-by-step explanation:

$\frac{5}{6}$ X $\frac{3}{10}$ = $\frac{15}{60}$ Just multiply the top numbers (numerators) and multiply the bottom numbers (denominators) across.

To simply, you can divide the top and bottom numbers by 15

$\frac{15}{60}$ ÷ $\frac{15}{15}$ = $\frac{1}{4}$

Assume the random variable x has a binomial distribution with the given probability of obtaining a success. Find the following.

borishaifa [10]

Answer:

P(x > 10) = 0.6981.

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

In this question:

$n = 14, p = 0.8$

P(x>10)

$P(x > 10) = P(X = 11) + P(X = 12) + P(X = 13) + P(X = 14)$

In which

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 11) = C_{14,11}.(0.8)^{11}.(0.2)^{3} = 0.2501$

$P(X = 12) = C_{14,12}.(0.8)^{12}.(0.2)^{2} = 0.2501$

$P(X = 13) = C_{14,13}.(0.8)^{13}.(0.2)^{1} = 0.1539$

$P(X = 14) = C_{14,14}.(0.8)^{14}.(0.2)^{0} = 0.0440$

$P(x > 10) = P(X = 11) + P(X = 12) + P(X = 13) + P(X = 14) = 0.2501 + 0.2501 + 0.1539 + 0.0440 = 0.6981$

So P(x > 10) = 0.6981.

Which equation represents a line which is parallel to the line 3y−2x=−24?

Blizzard [7]

Answer:

Any equation of the line with slope 2/3.

Parallel lines have identical slope.

Step-by-step explanation:

3y - 2x = - 24

3y = 2x - 24

y = 2/3x - 8

antiseptic1488 [7]

Answer:

Option b, c and e are wonderful approaches to solve the problem.

Step-by-step explanation:

Option (b) is appropriate this is because the option is talking about Simple random sampling where random universities are chosen to remove bias.

Option (c) is correct because this is an example of Stratified sampling where two homogenous groups (private and public universities are considered) and samples are chosen at random to remove bias

Option (e) is correct because this again is an example of Simple random sampling where 60 random STEM majors are chosen at random.

5000 principal earning 4% compounded annually, 7 years

almond37 [142]

Answer:

Step-by-step explanation:

Basically, you want to know interest. I = prt is the formula. 'I' will be left blank b/c that's unknown. P is principal, 5000. R is rate, 4%, or 0.04 when turned into a decimal. T is time, 7 years. So now when using the formula, it will all become I = 5000(0.04)(7). What that means is you first multiply 5,000 by 0.04, getting 200. Then when you multiply 200 by 7, it's 1,400, which will leave you with I = 1,400. Interest is 1,400.
