Answer:

  4.63%

Step-by-step explanation:

You want the interest rate that, compounded quarterly, will result in a balance of $216,000 for an investment of $90,000 after 19 years.

The formula for the balance of an account earning compound interest is ...

  A = P(1 +r/n)^(nt)

where P is the principal invested, r is the annual interest rate, n is the number of times per year interest is compounded, and t is the number of years.

Filling in the given values, we can solve for r:

  216000 = 90000(1 +r/4)^(4·19)

  2.4 = (1 + r/4)^76 . . . . . divide by 90,000

  2.4^(1/76) = 1 +r/4 . . . . . . take the 76th root

  (2.4^(1/76) -1) = r/4 . . . . . . subtract 1

  r = 4(2.4^(1/76) -1) ≈ 0.0463437 ≈ 4.63%

The required interest rate is about 4.63%.

A study is conducted to see if a daily exercise intervention affects blood pressure among people with pre-hypertension. The study design being used is a randomized controlled trial (RCT).

Generally,  In an RCT, the study participants are randomly assigned to either the intervention group or the control group. This helps to ensure that any differences between the two groups are not due to preexisting differences between them, but rather are due to the intervention being tested.

In this case, the intervention is a daily exercise intervention, and the outcome being measured is blood pressure among people with pre-hypertension.

The control group serves as a comparison group, and any changes in blood pressure observed in the intervention group can be attributed to the intervention rather than other factors.

Answer:

29, 61

Step-by-step explanation:

x = smaller

y = larger

y = 3x - 26

x + y = 90

x + 3x - 26 = 90

4x - 26 = 90

4x = 116

x = 29

x + y = 90

29 + y = 90

y = 90 - 29

y = 61

Answer:

smaller angle = 29°

larger angle = 61°

Step-by-step explanation:

Let x be the larger angle and y be the smaller angle

Larger angle is 26° less than 3 times the smaller angle

i. e x = 3y-26°

Since x and y are complementary angles, we can write,

x + y = 90°

or, (3y - 26°) + y = 90°

or, 4y = 90° + 26°

or, y = 116°/4

or, y = 29°

So,

x = 3 * 29° - 26° = 61°

The statement that is correct based on the data is that the table shows a proportional relationship

From the question, we have the following parameters that can be used in our computation:

Mango Used Smoothie Size

Kim 1 8 oz

Bri 3 24 oz

Angela 4 32 oz

Express  properly

So, we have

        Mango Used Smoothie Size

Kim         1                       8 oz

Bri           3                       24 oz

Angela    4                        32 oz

Start by checking if the table has a constant rate

This is represented as

Constant rate = Smoothie Size/Mango Used

So, we have

Constant rate = 8/1 = 8

Constant rate = 24/3 = 8

Constant rate = 32/4 = 8

See that the constant rate is the same for all values

Hence, the table shows a proportional relationship

Lisa's change in speed is 4 miles per hour.Lisa's acceleration is 2 miles per hour.

According to the question,

The speed of Lisa is = 3 miles per hour

A dog starts to chase her, and she  speeds up to seven miles per hour.

The change in speed after dog chase her is,

= 7 miles per hour - 3 miles per hour

= 4 miles per hour

Lisa's change in speed is 4 miles per hour.

When Lisa increased her speed in letter c,  the increase took two seconds.

Then,

The Lisa acceleration is,

Acceleration = Change in speed/Change in time

Acceleration = 4/2
