bert is planning to open a savings account that earns 1.6% simple interest yearly. He wants to earn exactly 128 interest in 2 ye

mina [271]

The formula for simple interest is I = prt, where I is the amount of interest, p is the principal invested, r is the rate as a decimal number and t is the amount of time. Substituting our given information we have
128 = p(0.016)(2) ----- 1.6% = 1.6/100 = 0.016
128 = p(0.032)
Divide both sides by 0.032:
128/0.032 = p(0.032)/0.032
4000 = p
He needs to invest $4000.

The figure below is rotated 270° clockwise about the origin .List the coordinates of the image.

meriva

Answer:

A (-4, -4), B (-2, 6), C (-1, 1), D(-3, -5)

Step-by-step explanation:

Before the rotation:

A (-4, 4), B (6, 2), C (1, 1), D(-5, 3)

270° rotation clockwise is the same as 90° counterclockwise. To do that transformation:

(x, y) → (-y, x)

Therefore, the coordinates of the rotated figure are:

A (-4, -4), B (-2, 6), C (-1, 1), D(-3, -5)

Use the normal distribution of fish lengths for which the mean is 11 inches and the standard deviation is 2 inches. assume the v

Kaylis [27]

To solve this problem, we make use of the z statistic. What we have to do here is to find for the z score using the given data and from the standard probability tables for z, we locate the proportion of the fish longer than 12 inches.

The formula for calculating the z score is:

z = (x – μ) / σ

where,

x = the sample value = 12 inches

μ = the sample mean = 11 inches

σ = 2 inches

so,

z = (12 – 11) / 2

z = 1 / 2

z = 0.5

Since we are looking for the values greater than 12, so this is a right tailed test. Using the tables, the value of p at this value of z is:

p (z = 0.5) = 0.3085

Therefore there is a 30.85% probability that the fish is longer than 12 inches.

The distributive property combines blank and blank to make multiplying whole numbers simpler.

laila [671]

The distributive property combines multiplication with addition and multiplication with subtraction together in order to simplify the equation. It is named as such because the number outside of the open and close parenthesis are distributed to the terms inside. Say for example, the equation given is 5(2x - 3). According to the distributive property, you distribute 5 by multiplying to each of the terms inside the parentheses. The solution would be: 5*2x + 5*-3 = 10x - 15. As you can see, it involved multiplication with addition and subtraction. Generally, you just have to add all the terms while making sure you carry the sign of the integer along when you multiply them just as shown in my example.
