Hal Fritz purchased a $5,000 bond at 95. The annual interest is 6%.
Trava [24]
Hi there :-)

Bond Cost = Face Value × Percent
5,000×0.95=4,750

Annual Interest=Face Value×Interest Rate
5,000×0.06=300

Annual Yield=Annual Interest×Bond Cost
(300÷4,750)×100=6.32%

Hope it helps

In △JKL, the measure of ZL=90°, KL = 11 feet, and JK = 32 feet. Find the measure of
Tanzania [10]

Answer:

x = 20.1 degrees

Step-by-step explanation:

Use the inverse sine function to calculate the angle measure. While the sine function uses the opposite and hypotenuse's angle measures, the inverse sine uses the side lengths of the opposite and hypotenuse.

Using something like desmos, plug in arcsin(11/32) and make sure you have selected degrees instead of radians in the setting to get the correct output.

Note that Inverse sine , cosine, and tangent can be written like arcsin, arccos, arctan or  sin^-1,  cos^-1, tan^-1.

x= 20.1

What is the fifth term of the sequence defined by the recursive rule f(1) = 5, f(n)=f(n-1) + 3
Oxana [17]

Answer:

f(5) = 17

Step-by-step explanation:

Using the recursive rule and f(1) = 5 , then

f(2) = f(1) + 3 = 5 + 3 = 8

f(3) = f(2) + 3 = 8 + 3 = 11

f(4) = f(3) + 3 = 11 + 3 = 14

f(5) = f(4) + 3 = 14 + 3 = 17

Suppose that Frida selects a ball by first picking one of two boxes at random and then selecting a ball from this box at random.
BaLLatris [955]

Answer:

3/4

Step-by-step explanation:

Given the following :

Number of boxes = 2

First box :

White balls = 3

Blue balls = 2

Second box:

White balls = 4

Blue balls = 1

What is the probability that Frida picked a ball from the first box if she has selected a blue ball?

Probability (P) = (required outcome / Total possible outcomes)

Probability of picking first box : P(F) = 1/2

Probability of not picking second box :P(S) 1/2

Probability of picking blue from first box : P(B | F) = 3/5

Probability of picking blue, but not from first box : P(Blue not from second box) P(B|S) = 1/5

probability that Frida picked a ball from the first box if she has selected a blue ball?

P(F) * P(B|F) ÷ (P(F) * P(B|F)) + (P(S) * P(B|S))

(1/2 * 3/5) ÷ ((1/2 *3/5) + (1/2 * 1/5)

3/10 ÷ (3/10 + 1/10)

3/10 ÷ 4/10

3/10 * 10/4

= 3/4

How do you know if a girl like you and what is x+10 divided by 6 = 1
strojnjashka [21]

Answer:

x = -2/3

Step-by-step explanation:

x + 10 ÷ 6 = 1

Divide

x + 1 2/3 = 1

Subtract 1 2/3

x = -2/3

Also, as a girl, we do give some signs to people that we like, we start conversations with the person, we make eye contact and then look away (at least that what I do lol), flirts with you, agrees with you, wants to spend time with you, etc.
