In expanded form that would be 4 + 0.2 + 0.09 + 0.003

Hope that helps :)

4 + .2 + .09 + .003 is 4.293 in expanded form.

Help with this question please

Tasya [4]

Let's simplify both sides to get:
$7y+14 = 9+8y-2$

Now we need to solve for y:
$14 = 9+y-2$
$14 = 7+y$
$y = 7$

So, your answer is A.

Please help me it’s due tonight and I’m stuck on this question!!

Answer:

The length of the ramp is 7.3 meters.

Step-by-step explanation:

The length of a triangle's side must be less than the sum of its two other sides. It also cannot have the same value as its other combined sides.

7 + 2 > 7.3

2 + 7.3 > 7

7 + 7.3 > 2

r is also longer than 7 meters, so that leaves option b. as your answer.

A binomial probability experiment is conducted with the given parameters. Compute the probability of x successes in the n indepe

Arlecino [84]

Answer:

P(4) =p(x=4) = 0.205078

Step-by-step explanation:

Explanation:-

The probability of x successes in the n independent trials of the experiment.

Given n=10, p=0.5,

By using Binomial distribution

$P(X =x) = n_{C_{x} } p^{x} q^{n-x}$

Given the p = 0.5

q=1-p =1-0.5=0.5

$P(X =4) = 10_{C_{4} } (0.5)^{4} (0.5)^{10-4}$

we will use formula

$n_{C_{r} } = \frac{n!}{(n-r)!r!}$

$10_{C_{4} } = \frac{10!}{(10-4)!4!}=\frac{10X9X8X7X6!}{6!4!} =\frac{10X9X8X7}{4X3X2X1} =210$

$P(X =4) = 210 (0.5)^{4} (0.5)^{10-4}$

$P(X =4) = 210 (0.5)^{4} (0.5)^{6}$

on calculation, we get

P(X=4) = 0.205078

Among many other pieces of information, the U.S. Census Bureau records the race or ethnicity of the residents of every county in

hram777 [196]

Answer:

The diversity index is 0.335 or 33.5%

Step-by-step explanation:

Probability index= probability that two people chosen at random are different ethnicity or races.

Let the probability of picking black = p(B) =0.15

probability of picking white= p(W)= 0.8

probability of picking Asian= p(A)=0.05

The probability of picking two people who are of different races or ethnicity can be gotten as:

Probability of picking: (White & Black) OR (White & Asian) OR (Black &Asian) OR (black &white) OR (Asian&white) OR (Asian& Black).

Using the notations given earlier, we can write the diversity index as:

Diversity index=p(W) x p(B)+ p(W) x p(A)+ p(B) x p(A) +p(B) x p(W)+ p(A) x p(W)+ p(A) x p(B)

Fixing the values for each term in the last expression gives:

Diversity index= 0.8x0.15 +0.8x0.05+ 0.15x0.05 +0.15x0.8+ 0.05x0.8+0.05x0.15

Diversity index= 0.12+0.04+0.0075+ 0.12+0.04+0.0075

Diversity index= 0.335 or 33.5%

Hence the diversity index is 0.335 or 33.5%
