Conditional Probability

1 answer:

3 0

To solve for P(QIR) we use the formula:
P(QIR)=[P(Q∩R)]/P(R)
But from the diagram:
P(Q∩R)=3/22
P(R)=7/22
hence
P(QIR)=3/22÷7/22=3/7

For her 1st birthday, Ruth's grandparents invested $1000 in an 18-year certificate for her that pays 10% compounded annually. Ho

Lyrx [107]

Answer:

The certificate will be worth $5,559.92 on Ruth's 19th birthday.

Step-by-step explanation:

The compound interest formula is given by:

$A = P(1 + \frac{r}{n})^{nt}$

Where A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit t and t is the time the money is invested or borrowed for.

In this problem, we have that:

$P = 1000, n = 1, r = 0.1, t = 18$

$A = 1000(1 + \frac{0.1}{1})^{1*18}$

$A = 5559.92$

The certificate will be worth $5,559.92 on Ruth's 19th birthday.

Answer:

Option D

Step-by-step explanation:

$F=\frac{9}{5}C+32\\\\F-32=\frac{9}{5}C \\\\5(F-32)=9C\\\\\frac{5(F-32)}{9}=C \\\\C=\frac{5}{9}( {F-32})$

For F=77°F

$C=\frac{5}{9}(F-32) \\\\C=\frac{5}{9}(77-32)\\\\C=\frac{5}{9}(45)\\\\C=\frac{225}{9} \\\\C=25$
