Yasmin buys 10 pounds of peaches. Peaches cost $1.95 per pound. How much did Yasmin pay for the peaches?
O $8.05
O $10.00
O $11.95
$19.50
Answer:
10 x 1.95 = 19.50 so D is your answer, $19.50
if Yasmin buys 10 pounds of peaches. Peaches cost $1.95 per pound then Yasmin pay $19.50 for the 10 pounds of peaches.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that Yasmin buys 10 pounds of peaches
Peaches cost $1.95 per pound
we need to calculate the amount has to pay by Yasmin for the peaches.
1 pound of peaches =$1.95
We need to calculate for 10 pounds.
Use multiplication to find the amount.
10×1.95
$19.5
Hence, if Yasmin buys 10 pounds of peaches. Peaches cost $1.95 per pound then Yasmin pay $19.50 for the 10 pounds of peaches.

A population’s instantaneous growth rate is the rate at which it grows for every instant in time. Function r gives the instantaneous growth rate of a fruit fly population x days after the start of an experiment.
Given:
The function is
[tex]r(x)=0.05(x^2+1)(x-6)[/tex]
where, function r gives the instantaneous growth rate of a fruit fly population x days after the start of an experiment.
To find:
Number of complex and real zeros.
Time intervals for which the population increased and population deceased.
Solution:
We have,
[tex]r(x)=0.05(x^2+1)(x-6)[/tex]
[tex]r(x)=0.05(x^3+x-6x^2-6)[/tex]
Here, degree of function x is 3. It means, the given function has 3 zeros.
From the given graph it is clear that, the graph of function r(x) intersect x-axis at once.
So, the given function r(x) has only one real root and other two real roots are complex.
Therefore, function r has 2 complex zeros and one real zero.
Before x=6, the graph of r(x) is below the x-axis and after that the graph of r(x) is above the x-axis.
Negative values of r(x) represents the decrease in population and positive value of r(x) represents the increase in population.
Therefore, based on instantaneous growth rate, the population decreased between 0 and 6 hours and the population increased after 6 hours.
Answer:
Function r has two complex zeros and one real zero. Based on the instantaneous growth rate, the population decreased between 0 and 6 hours and the population increased after 6 hours.

Franco has a hat with 9 blue marbles, 4 yellow marbles, and 12 green marbles. He designs a binomial experiment by drawing a marble from the hat, recording whether the marble is green, and then laying the marble aside. He then repeat the process seven times. Which statement must be true?
A. The experiment is not a binomial experiment because there is not a fixed number of drawings.
B. The experiment is not a binomial experiment because the probability of choosing a green marble is the same for each drawing.
C. The experiment is not a binomial experiment because the probability of choosing a green marble is not the same fo each drawing.
D. The experiment is not a binomial experiment because there are only two possible outcomes for each drawing.
Answer:
C: The experiment is not a binomial experiment because the probability of choosing a green marble is not the same for each drawing.
Step-by-step explanation:
Just took the Binomial Distribution Quiz on Edge.
The experiment is not a binomial experiment because the probability of choosing a green marble is not same for each drawing
What is binomial experiment ?
An experiment consisting of a fixed number of independent trials each with two possible outcomes, success and failure .
The experiment is not a binomial experiment because the probability of choosing a green marble is not the same for each as after drawing the marble from hat , he is laying the marble aside and not putting it back into the hat which altered the probability every time because total number of marbles are decreasing after every turn of drawing.
hence , correct answer is

The scale on a map shows that 2 inches represents 15 miles. Which proportion can be used to find the actual distance,
X, represented by 30 inches on the map?
2 30
15
2 X
1530
15
2
0 30
15 X
302
Answer:
The proportion that can be used is
2 inches 30 inches
15 miles x
Step-by-step explanation:
If 15 miles is 2 inches and 30 divided by 2 is 15, you have to multiply 15 by 15 to figure out how many miles 30 inches is. Because 15 x 15 = 225, 30 inches is 225 miles. Therefore, x = 225.

Step-by-step explanation:
y
y=ax
where a is a constant of proportionality;
y=20, x=4
20=4a
a=20/4
a=5
y=5x
The constant of variation is 5
The constant of variation for the given relationship is 5.
What is Direct Variation?Direct variations are defined as the functions of the form y = kx, where k is a constant.
Here when y increases, x increases and if y decreases, x also decreases.
Given that,
y varies directly as x
So the equation will be of the form,
y = kx
Here k is the constant of variation.
Given, y is 20 when x is 4.
So, 20 = 4k
k = 20 / 4 = 5
Hence the constant of variation for the given relationship is 5.

Answer:
What is 198/264 Simplified?
3/4 is the simplified fraction for 198/264.
Step-by-step explanation:
Answer:
3/4.
Step-by-step explanation:
Find the prime factors:
198 = 2 * 99
99 = 3 * 3 * 11
So 198 = 2 * 3 * 3 * 11.
264 = 4 * 66 = 2 *2 * 66
66 = 2 * 3 * 11
So 264 = 2 * 2 * 2 * 3 * 11.
Now we find the Greatest common factor os the 2 numbers:
It is 2 * 3 * 11 = 66.
Therefore we can now simplify the fraction:
198/66 / 264/66
= 3/4.
