The mean of 5 numbers is 14. If the first four numbers in the data set are 12, 17, 24, and

NISA [10]

Answer:

a. x + 64 = 70

b. x = 6

Step-by-step explanation:

Let the fifth number be x.

$\implies \: mean = \frac{sum \: of \: the \: numbers}{total \: numbers} \\ \\ \implies \: 14 = \frac{12 + 17 + 24 + 11 + x}{5} \\ \\ \implies \: 14 = \frac{64 + x}{5} \\ \\ \implies \: 14 \times 5 =x+ 64 \\ \\\implies \:\purple{\bold{x+ 64 =70}}\\(this \: is \:the \: required\: equation)\\ \\ \implies \: x= 70 - 64 \\ \\ \implies \: x = 6$

Jeremy bought a new truck for $32,000. The value of the truck after t years can be represented by the formula V = 32,000(.8)^t.

blondinia [14]

$6700=32000(0.8)^t$
divide both sides by 32000
$\frac{67}{320}=0.8^t$
take the ln of both sides
$ln( \frac{67}{320})=ln(0.8^t)$
using the property that $ln(a^b)=b(ln(a))$
$ln( \frac{67}{320})=t(ln(0.8))$
divide both sides by ln(0.8)
$\frac{ln( \frac{67}{320}) }{ln(0.8)} =t$
use calculator
7.00728=t
so in about 7 years

You invest $2000 in an account at 4.5% per year simple interest. How much will you have in the account at the beginning of the 8

77julia77 [94]

I will have $2721 at the beginning of the eighth year.

The beginning of the eighth year is the end of <em>seven years of investing</em>.

The formula for the future value (FV) of my investment is

FV = <em>C</em>(1 + <em>r</em>)^<em>n</em>

where <em>C</em> = my initial cash

<em>r</em> = the interest rate

<em>n</em> = the number of years

FV = $2000(1.045)^7 = $2722

Factor the trinomial 6y squared + 19y + 15

Musya8 [376]

Answer:

1.y = -5/3 = -1.667

2. y = -3/2 = -1.500

Step-by-step explanation:

90 + -1 = -91

-45 + -2 = -47

-30 + -3 = -33

-18 + -5 = -23

-15 + -6 = -21

-10 + -9 = -19

-9 + -10 = -19

-6 + -15 = -21

-5 + -18 = -23

-3 + -30 = -33

-2 + -45 = -47

-1 + -90 = -91

1 + 90 = 91

2 + 45 = 47

3 + 30 = 33

5 + 18 = 23

6 + 15 = 21

9 + 10 = 19
