What is the unit rate in words?

1 answer:

4 0

When rates are expressed as a quantity of 1, such as 2 feet per second<span> or </span>5 miles per hour<span>, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.</span>

Two players, A and B, alternately and independently flip a coin and the firstplayer to obtain a head wins. Assume player A flips

mart [117]

Answer:

Probability that A wins is 2/3.

Step-by-step explanation:

player A can win in 2 ways

1) Player A wins immediately by getting head

2) Player A loses immediately by getting tail but wins ultimately as player B gets losses.

a) Probability of 1 to happen is 1/2.

b) Similarly for the event 2 to happen the condition is that A get's a tail and B losses.

Let probability that A wins is 'p' thus we have

$p=P(1)+P(2)\\\\p=\frac{1}{2}+\frac{1}{2}\times (1-p)\\\\$

Solving for 'p' we get

p= 2/3.

A certain company has a fixed cost of $200 per day. It costs the company $3.10 per unit to make its products. The company is

Alex17521 [72]

Answer:

a. The horizontal asymptote of y = 3.10 represents that the average cost per unit will approach $3.10 as the number of units produced increases.

Step-by-step explanation:

A certain company has a fixed cost of $200 per day. Then it costs the company $3.10 per unit to make its products.

So, the total cost will be,

Then average cost f(x) will be,

As this an equation of hyperbola (rectangular hyperbola).

Its vertical asymptote is (equating denominator to zero),

i.e y axis.

Its horizontal asymptote is (leading coefficient of numerator divided by leading coefficient of denominator),

As x approaches infinity, f(x) approaches 3.10.

Therefore, option a is correct.

M = y2 - y1 / x2 - x1 What is the slope of line JK? A) 5/9 B) 9/5 C) -5/9 D) -9/5

meriva

So
(x,y)

J is -4 to the right and 2 up so
(-4,2)

K is 5 to the right and -3 up
(5,-3)

(x,y)

x1=-4
y1=2
x2=5
y2=-3

M= $\frac{y2-y1}{x2-x1}$
M= $\frac{-3-2}{5-(-4)$
M= $\frac{-5}{5+4}$
M= $\frac{-5}{9}$

answer is C -5/9

If it is including herself then Kali would've started with 17 pieces of candy. But if it isn't herself then she would've started with 10 pieces of candy. Hope that helps.
