G and H are mutually exclusive events. • P(G) = 0.5 • P(H) = 0.2

Answers

Answer:

[tex]P(G\ or\ H) = 0.7[/tex]

Step-by-step explanation:

Given

[tex]P(G) = 0.5[/tex]

[tex]P(H) = 0.2[/tex]

Required [Missing from the question]

[tex]P(G\ or\ H)[/tex]

Because the events are mutually exclusive, we use:

[tex]P(G\ or\ H) = P(G) + P(H)[/tex]

So, we have:

[tex]P(G\ or\ H) = 0.5 + 0.2[/tex]

[tex]P(G\ or\ H) = 0.7[/tex]

$987.65 is invested at 0.4% annual interest for 5 years.
a. Simple Interest b. Compound Interest

Answers

Answer:

I. Simple interest = $19.753

II. Compound interest = $1007.6

Step-by-step explanation:

Given the following data;

Principal = $987.65

Interest rate, R = 0.4%

Time, T = 5 years

To find the simple interest;

S.I = PRT/100

S.I = (987.65*0.4*5)/100

S.I = 1975.3/100

S.I = $19.753

II. To find the compound interest;

[tex] A = P(1 + \frac{r}{100})^{t}[/tex]

Substituting into the formula, we have;

[tex] A = 987.65(1 + \frac{0.4}{100})^{5}[/tex]

[tex] A = 987.65(1 + 0.004)^{5} [/tex]

[tex] A = 987.65(1.004)^{5} [/tex]

[tex] A = 987.65(1.0202)[/tex]

A = $1007.6

Carmen's father is 28 years older than her, 3 years ago we was 5 times her age, what are their ages?

The best centre of measure for this data is the mean which is equal to 10.90 seconds.

Mean, median and mode are use to measure for central tendency. Therefore, let's arrange the values in ascending order.

10.72, 10.75, 10.78, 10.80, 10.80, 10.88, 10.96, 10.99, 11.02, 11.10, 11.10,

According to the data, the values are very close to catch. Therefore, the mean will be used. Therefore,

mean = sum of data / number of data

mean = 10.72 + 10.75 + 10.78 + 10.80 + 10.80 + 10.88 + 10.96 + 10.99, 11.02 + 11.10 + 11.10  / 11

mean = 119.9 / 11

mean = 10.90

Za and Zb are
complementary angles. Za measures 59º.
What is the measure of Zb?

Answers

Complementary angles are two angles whose sum adds up to 90 degrees
Za + Zb = 90
You know Za measures 59
59 + Zb = 90

Solution: Zb is 31 degrees

Answer:

Zb = 31

Step-by-step explanation:

Complementary angles mean that the angles add up to 90 so:

Za + Zb = 90

59 + Zb = 90

Zb = 90 - 59

Zb = 31
