In order for the two investments to yield at least $1550, the remainder of the money has to earn an interest of 7%.

<h3 /><h3>Equation that can be derived from the question</h3>

The formula that can be used to determine simple interest is: principal x time x interest rate.

0.12(10,000) + x($5000) = $1550

$1,200 + 5000x = $1550

Where:

x = interest rate paid in the account where $5000 was deposited.

<h3>Determination of the interest rate</h3>

In the above equation, combine similar terms:

$5000x = $1550 - $1200

Add similar terms together

$5000x = $350

Divide both sides of the equation by 500

x = $350 / 5000

x = 0.07

x = 7%

What is the value of the expression –4x3 when x = –2? A. –24 B. –32 C. 32 D. 24
timurjin [86]
Answer to your question would be 
c. 32
Because you would first have to multiply -4 and -2, and a negative times a negative times a negative equals a positive so -4 times -2 = 8 and then 8 times 3 equals 32 so the answer would be 32.

Answer:

C. m<C = m<F

Step-by-step explanation:

this is because in their triangle names, they are in the same spot (third letter of the name)

if they are in the same spot, they <em>have</em> to be congruent

same goes for the other letters, <A has to be congruent to <D and <B has to be congruent to <E

Zucchini weights are approximately normally distributed with mean 0.8 pound and standard deviation 0.25 pound. Which of the foll
Charra [1.4K]

Answer:

0.81859

Step-by-step explanation:

We solve using z score method

The formula for calculating a z-score is is z = (x-μ)/σ,

where

x is the raw score

μ is the population mean

σ is the population standard deviation.

Mean 0.8 pound

Standard deviation 0.25 pound

For x = 0.55 pound

z = 0.55 - 0.8/0.25

= -1

Probability -value from Z-Table:

P(x = 0.55) = 0.15866

For x = 1.3 pounds

Z = 1.3 = 0.8/0.25

= 2

Probability value from Z-Table:

P(x = 1.3) = 0.97725

The probability that a randomly selected zucchini will weigh between 0.55 pound and 1.3 pounds is

P(x = 1.3) - P(x = 0.8)

0.97725 - 0.15866

0.81859.
