An urn contains 5 red marbles 9 white and 7 blue marbles marbles.A child randomly selects three (without replacement) from the urn.Round to four decimal place.Find the probability all marbles are the same.
Answer:
0.0970
Step-by-step explanation:
Red marbles, R= 5
White, W = 9
Blue, B = 7
Total = (5 + 9 + 7) = 21
Selecting 3 marbles without replacement :
Probability that all marbles are the same
P(RRR) or P(BBB) or P(WWW)
(5/21 * 4/20 * 3/19) + (7/21 * 6/20 * 5/19) + (9/21 * 8/20 * 7/19)
0.0075187 + 0.0263157 + 0.0631578
= 0.0969922

Find the sum of all multiples of 7 lying between
500 & 900
Answer:
Sₙ = 57/2 * (504 + 896) = 39900
Step-by-step explanation:
first multiple of 7 after 500 is: 72 *7 = 504
last multiple of 7 before 900 is: 128 *7 = 896
a₁ = 504
aₙ = 896
where n = 128-72 +1 = 57
sum of arithmetic sequence: Sₙ = n/2 * (a₁ + aₙ)
Sₙ = 57/2 * (504 + 896) = 39900

The vertex form of the equation of a parabola is y = (x + 7)2 + 13. What is the standard form of the equation? O A. y = 7x2 + 14x+ 62 O B. y = x2 + 43x + 32 O c. y = x2 + 7x + 13 O D. y= x2 + 14x + 62
Answer:
y = x^2 + 14x + 62
Step-by-step explanation:
y = (x + 7)^2 + 13 is to be rewritten in the form y = ax^2 + bx + c.
Note: Use " ^ " to denote exponentiation.
Expand y = (x + 7)^2, holding the constant term to be added on later:
y = x^2 + 14x + 49 + 13
Combining the constants, we get:
y = x^2 + 14x + 62 (which matches Answer D).

The population density of City A is 6000 people per square mile. City B is a dilation of City A with scale factor 1.5 . If City B has 3/5 of the population of City A, what is the population density of City B?
Answer:
[tex]1600\ \text{people per square mile}[/tex]
Step-by-step explanation:
Number of people per square mile in City A is 6000.
In terms of size City B is a dilation of City A with scale factor 1.5.
This means a length of 1 mile in city A would be 1.5 miles in city B.
So, [tex]1\ \text{mile}^2\text{ in City A}=1.5^2\ \text{mile}^2\text{ in City B}[/tex]
City B has [tex]\dfrac{3}{5}[/tex] of the population of City A.
So the population density of City B would be
[tex]\dfrac{\dfrac{3}{5}\times 6000}{1.5^2}=1600\ \text{people per square mile}[/tex]
The population density of City B is [tex]1600\ \text{people per square mile}[/tex].

Answer:
m = 3/2
Step-by-step explanation:
You want to find the slope, or the change in y coordinates over change in x-coordinates.
The first given point is E(-2, -4)
The second point is F(2, 2)
Coordinates are given in (x, y), so following the equation and computing the x and y coordinates of E - F for both the numerator and denominator:
[tex]\frac{y_2 - y_1}{x_2-x_1} = \frac{-4 -2}{-2 -2} = \frac{-6}{-4} = \frac{3}{2}[/tex]
You could also have went the other way and calculated F - E for the numerator and denominator and get the same answer.
Finally, to check you can also look at the graph through the rise over run (rise/run) method and see that from E, you go up 3 (rise) and to the right 2 (run) to get to the next point on the line.
After driving for 2 hours, Juan is 110 miles from his home. After driving 5 hours, he is 275 miles from his home. What is his average rate of change?
Answer:
392
Step-by-step explanation:
The average rate of change will be "55 m/h".
According to the question,
→ After 2 hours (t₁),
Juan is 110 miles (d₁) from his home.
→ After 5 hours (t₂),
Juan is 275 miles (d₂) from his home.
→ The average rate of change will be:
= [tex]\frac{d_1+d_2}{t_1+t_2}[/tex]
By substituting the values, we get
= [tex]\frac{110+275}{2+5}[/tex]
= [tex]\frac{385}{7}[/tex]
= [tex]55 \ m/h[/tex]
Thus the above is the right solution.

A rectangular prism is given,
Geometry can be defined as the branch of mathematics that is concerned with the size, shape, and orientation of two-dimensional figures.
As we know in the rectangular prism there are eight vertices and six faces.
From the figure, we can see clearly that point D is coplanar with A, B, and C.
Point D is coplanar with A, B, and, C.
Thus, point D is coplanar with A, B, and C because it is on the same plane as A, B, and C option (4) is correct.

The bank contains pennies, nickels, dimes, and quarters. There are 4 more nickels than pennies. How much money does the bank contain
Of the 50 coins 10% are pennies and 42% are dimes
The amount of money in the bank contains 5 pennies, 9 nickels, 21 dimes, and 15 quarters.
What is a numerical expression?A numerical expression is algebraic information stated in the form of numbers and variables that are unknown.
First, let's find the number of pennies in the bank.
Since 10% of the coins are pennies, and there is 50 coins total, the number of pennies is :
10/100 × 50 = 5
Now let's find the number of dimes. Since 42% of the coins are dimes, and there is 50 coins total, the number of dimes is :
42/100 × 50 = 21
Since there are 4 more nickels than pennies, the number of nickels is :
5 + 4 = 9
Finally, the number of quarters is: 50 - 5 - 9 - 21 = 15
Thus, the bank contains 5 pennies, 9 nickels, 21 dimes, and 15 quarters.
