Please choose the answer that describes the scientific notation for 5,098,000.a. 5.098 108
b. 5.098 75777
c. 5.098 106
d. 5.098 107

Answers

Answer 1
Answer: Scientific notation is the representation of a number in a power of ten, with a sequence of digits placing the comma after the first digit, and the power or then that is mathematically consistent with the number. For example 400 is 4.00 * 10^2; 3100 is 3.100 * 10^4; 13421 = 1.3421 * 10 ^4. It is important that you have only one digit before the comma. So, 5,098,00 is 5.098 * 1,000,00 = 5.098 * 10^6. The answer is the option c. 5.098 * 10^6.

The average of the numbers would not change

Answer:

Did not change.

Step-by-step explanation:

This is because the average is based off the total sum of all the constituents. Thus adding 10 and subtracting 10 doesn't change anything.

. What is the slope of the line with the equation 2x + 3y + 6 = 0 ?

Answers

-2/3. You take 3y and move it to the opposite side. Then you would take the three from the 3Y and divide everything by three, so you get -2/3x+2=Y then you look at what the coefficient is in front of X and X equals -2/3, which is your slope.
2x + 3y + 6 = 0 \n \n3y=-2x-6 /:3\n \ny=-(2)/(3)x-(6)/(3)\n \ny=-(2)/(3)x-2

Answer : \ is \ your \ slope : \ \ m = -(2)/(3)

Which r–value represents the strongest negative correlation?A. –0.7
B. –0.22
C. 0.38
D. 0.9

Answers

The best answer to the statistics question above would be letter A. The r-value that represents the strongest negative correlation among the given choices would be -0.7. This is because the magnitude of the correlation ranges from .7 to .9 which indicates a strong correlation. The negative sign connotes the negative relationship.

Answer:

A.

Step-by-step explanation:

Ashley invests $9,720 in a one-month money market account paying 3.16% simple annual interest and $8,140 in a two-year CD yielding 3.23% simple annual interest. Assuming Ashley does not reinvest or renew these investments, how much money will she have when both investments reach maturity, to the nearest dollar?a.
$550
b.
$1,080
c.
$17,310
d.
$18,411

Answers

Answer:

Total Amount ≈ $18,411.59

D.

Step-by-step explanation:

In order to determine the total amount that Ashley will possess when both investments reach maturity, one may utilize the formula for simple interest:

Simple Interest (I) = P * r * t

Where:

I = Interest earned

P = Principal amount (initial investment)

r = Annual interest rate (expressed as a decimal)

t = Time (in years)

The interest for each investment may be calculated as follows:

For the one-month money market account:

P1 = $9,720

r1 = 3.16% or 0.0316 (as a decimal)

t1 = 1/12 year (one month is 1/12 of a year)

I1 = 9,720 * 0.0316 * (1/12) = $25.63 (rounded to the nearest cent)

For the two-year CD:

P2 = $8,140

r2 = 3.23% or 0.0323 (as a decimal)

t2 = 2 years

I2 = 8,140 * 0.0323 * 2 = $524.96

The total amount that Ashley will possess when both investments reach maturity may now be calculated as follows:

Total Amount = P1 + I1 + P2 + I2

Total Amount = $9,720 + $25.63 + $8,140 + $524.96

Total Amount ≈ $18,411.59

Rounded to the nearest dollar, Ashley will possess approximately $18,412 when both investments reach maturity.
