Answer: Well since the ratio is 9:7 for red to blue well transfer that first by finding out the blue if there are 117 xc=9:7x13 would be 117 red and 7x13=91 blue so the new ratio is 117:91.

So now we add which I'm sure you can do,

Answer:

He will receive $515 for the 17 coins

Step-by-step explanation:

In this question, we are asked to calculate how much will be received for 17 coins , with each coin having a specific value in the US currency.

Obviously, there are four coins, so let’s proceed to get the amount he gets per type of coins.

For the m coin, she has 3 pieces. One m coin has a value of $10, then the amount of coins she makes on the m coins will be 3 * 10 = $30

For the a coin, he has 7 pieces. One m coin has a value of $5, then the amount of coins she makes on the a coins will be 7 * 5 = $35

For the t coin, he has 5 pieces. One t coin has a value of $50, then the amount of coins she makes on the t coins will be 5 * 50= $250

For the h coin, she has 2 pieces. One h coin has a value of $100, then the amount of coins she makes on the h coins will be 2* 100 = $200

The total amount made on the 17 coins would thus be mathematically equal to;

Amount made on m coins + Amount made on a coins + Amount made on t coins + Amount made on h coins

The total amount = $30 + $35 + $250 + $200 = $515

10-mg Atorvastatin Placebo Headache 15 65 No headache 17 3 3. If two different subjects are randomly selected, find the probabil

balu736 [363]

Answer:

0.6384

Step-by-step explanation:

Given that:

10-mg Atorvastatin Placebo Headache 15 65 No headache 17 3

Hence the total of number of patients = 15 + 65 + 17 + 3 = 100 patients

The number of patients with headache = 15 + 65 = 80 patients

Also, C(n, x) is the number of combinations in which n items can be chosen taken x at a time it is given by the formula:

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

The the probability that if two different subjects they both had a headache = $\frac{C(80,2)}{C(100,2)}=\frac{\frac{80!}{(80-2)!2!} }{\frac{100!}{(100-2)!2!} } =\frac{3160}{4950}=0.6384$

All seasons plumbing has two service trucks that frequently need repair. if the probability the first truck is available is .74,

faltersainse [42]

Availability of first truck probability P (1) = 0.74
Availability of second truck probability P (2) = 0.57
Availability of both truck probability P (1 and 2) = 0.46
So the probability of at least one available P (1 or 2) = P (1) + P (2) - P (1 and 2) = 0.74 + 0.57 - 0.46 = 0.85
Now the probability of at neither available = 1 - P (1 or 2) = 1 â€“ 0.85 = 0.15
