Answer:

C, D

Step-by-step explanation:

These equations are written in slope-intercept form, or y=mx+b, where m is the slope and b is the y-intercept.

Looking at the first one (y=-7x+2), we notice m=-7 and b=2. Therefore, It is choice C because the slop (m) is 7 and the y-intercept (b) is 2. We can do the same for the second one (y=1/8x+3). We know that m=1/8x and b=3, so the answer is choice D because the slope is 1/8 and the y-intercept is 3. Hope this helps!

A group of 300 housewives was interviewed to determine if there is a preference for one of two detergents. Detergent A was favor
san4es73 [151]

Answer: Using Chi-square.

Step-by-step explanation: To check if the provided data show any differences in preference for the two detergents (i.e., two variables), a Chi-square can be deployed, as it is used to test the goodness of fit, and test if two variables are related.

If the value obtained is less than 0.05, it means that there is statistical difference between the preference for the two detergents.

However, if the obtained value is higher than 0.05, it translates that there is no statistical difference between the preference for the two detergents.

5. Find the center and radius of the circle with the given equation.
leonid [27]

Answer:

A

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x + 4)² + (y - 1)² = 25 ← is in standard form

with centre = (- 4, 1 ) and r = \sqrt{25} = 5 → A

Jenn invests $2150 at 2% compounded continuously. How many years will it take her to accumulate $2733.19 in the account?
gavmur [86]

Answer:

12 years

Step-by-step explanation:

From the formula;

A = P(1 + r)^n

A = Amount  = $2733.19

P = Principal = $2150

r = rate = 2%

n = time in years = ???

2733.19 = 2150(1 + 0.02)^n

2733.19/2150 = (1 + 0.02)^n

1.27 = (1.02)^n

Taking logarithm of both sides

log 1.27 = n log 1.02

n= log 1.27/log 1.02

n= 0.1038/0.0086

n = 12 years
