MatroZZZ [7]

Answer:

240.

Step-by-step explanation:

Here is the correct question: Three sister are getting new outfits. shirts cost 11 each,skirts coat 25 each and shoes cost 44 a pair. what is the total cost of the new outfits for all of the sisters?

Given: Cost of each shirt is 11

Cost of each skirts coat is 25

Cost of each pair of shoes cost is 44.

Now, finding total cost of shirt, skirt coat and shoes as cost of one new outfit.

= $11+25+44 = 80$

∴ Total cost of one new outfit is 80.

Next, finding cost of new outfit for all, three sisters.

Cost of new outfit for three sister = $\textrm { cost of one outfit}\times \textrm{ number of sisters}$

∴ Cost of new outfit for three sister = $80\times 3= 240$

240 is the total cost of new outfit for all the sisters.

A human gene carries a certain disease from the mother to the child with a probability rate of 34%. That is, there is a 34% chan

eimsori [14]

Answer:

The probability that at least one of the children get the disease from their mother is P=0.7125.

Step-by-step explanation:

This can be modeled as a binomial random variable.

The parameter p=0.34 is the probability of a child being infected, and is constant and independent of the other events.

The parameter n=3 is the number of children (sample size).

Then, we have to calculate the probabilty that at least one of the children get the disease from their mother. That is:

$P(x\geq1)$

The probability of exactly k children being infected can be calculated as:

$P(x=k) = \dbinom{n}{k} p^{k}(1-p)^{n-k}$

Then, the easiest way to calculate this probability is using the complement: the value of the probability is 1 (or 100%) less the probability that no children gets infected.

$P(x\geq1)=1-P(x=0)\\\\\\P(x=0) = \dbinom{3}{0} p^{0}(1-p)^{3}=1*1*0.2875=0.2875\\\\\\P(x\geq1)=1-0.2875=0.7125$

MULTIPLE CHOICE

ddd [48]

The answer is B, 57 degrees. You can tell angle C is 57 degrees since 180-123 is 57 and both angles add up to 180 on a straight line. Then since the lines are parallel, angle a is 55 degrees because of alternate interior angle theorem. Then, a triangle’s angles add up to 180 so to figure out angle d, you do: 180- (55 + 57) which gives you 68. Since 55 + angle b + angle d = 180, you have to do 180 - (68+55) = 57 degrees. Hope this helps!
