Two random integers, a and b, are independently chosen, with replacement, from 1 to 1000, inclusive. What is the probability that both 2^a 2^b and 3^a 3^b are multiples of 5
Answer:
The probability is zero
Step-by-step explanation:
For a number to be a multiple of 5, the number must end with either 0 or 5
These are the only numbers in which we can have 5 as a factor of
Now when we raise 2 to any number, there are only some sets of possible results
These numbers are only multiples of 2
These can be;
2, 4, 6 and 8
No root of two has its end in 0 or 5, so none has 5 has its factor
Let us now look at 3
The multiples of 3 when raised are;
3,9,1,7,
As we can see, at no point do we have 5 or 0 as the result
So since we have none of both as ending 5 or 0, the probability we are looking for is zero

Write the equation of the line that passes through the points (-9,-4) and (-9,4).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.
Answer:
x = -9
Step-by-step explanation:
x = -9 would be the slope because when you see the two points for each coordinate there is no x value but we do see a straight line and we see that there is no y-intercept. So, x= -9 would be the answer. Hope this helps.
Could someone help me with this? Please provide an explanation! Thank you!
Answer:
if you are solving for x then the answer would be -17/6 or -2 5/6 (mixed number form)

A building is 50 feet tall and casts a 25 foot shadow. If Mark is 6 feet tall, how long would
his shadow be?
Answer:
Mark's shadow would be 3 feet.
Step-by-step explanation:
If a building is 50 feet tall and casts a 25 foot shadow, then the shadow of an object is 1/2 the length of the actual object.
This can be supported by the division problem:
50 ÷ 2 = 25
If Mark is 6 feet tall, then we need to divide 6 by 2 in order to find the length of the shadow.
6 ÷ 2 = 3
Therefore, Mark's shadow would be 3 feet.
Hope this helps! :D

(-3, -2)
(-2, -3)
(-3, 2)
(2, -3)
Answer:
(-2,-3)
Step-by-step explanation:
I took the test and got it wrong at first but seen the correct answer when I looked at my results.
The turning point of the function f(x) = |x+3| -2 will be (-3, -2).
What is an absolute function?The non-negative value of a real number x without regard to its sign is known as its absolute value or modulus in mathematics and is indicated by the symbol |x|.
Given that the absolute function is f(x) = |x+3| -2. When we plot the graph of the absolute function f(x) = |x+3| -2 it will give two straight lines the first line is on the left side and the second line is on the right side. The graph of the function changes its position at the coordinate ( -3,-2).
Therefore, the absolute function is having its turning point at the coordinate ( -3,-2).

A recording studio charges musicians an initial fee of $50 to record an album. Studio time costs an additional $75 per hour. Write a linear model that represents the total cost C of recording an album as a function of studio time(in hours). Use the variable t to represent the number of hours the recording studio is used
Answer:
C=$50+$75×T
Step-by-step explanation:
$50 is the amount charged to record an album + 75 amount charged per hour ×T which is how much hours you are going to record an audio.

Triangle A is reflected in the x axis to give triangle B, which is then reflected in the line y=x to give Triangle C. Draw Triangle C.
Answer:
The coordinates of triangle C on the grid are
(-5,4) , (-2,2) and (-2,4)
Step-by-step explanation:
We can identify the coordinates of the vertices of the triangles so as to get a diagram
For the first triangle, we have the following coordinates;
(4,5) , (2,2) and (4,2)
Now, let us get the coordinates of triangle B after reflecting triangle A in the x-axis
what we have in this case is that the x-axis coordinates stays same while the y-axis values are negated
Hence, the coordinates of triangle B are;
(4,-5) , (2,-2) and (4,-2)
Lastly we are to reflect triangle B in the line y = x so we get triangle C
A reflection over the line y= x means that we are going to switch the place of the x and y coordinates of the pre-image
So, the coordinates of triangle C are;
(-5,4) , (-2,2) and (-2,4)
The coordinates of triangle C are (-5,4) , (-2,2) and (-2,4)
From the given image the vertices of the triangles are
Triangle A has coordinates (4,5) , (2,2) and (4,2)
After reflecting triangle A in the x-axis, triangle B is obtained
On reflection in x-axis, the x-axis coordinates remain same while the y-axis coordinates become negative with the same magnitude.
Hence, the coordinates of triangle B are (4,-5),(2,-2) and (4,-2)
Now as triangle B is reflected by the line y = x to get triangle C, the x and y coordinates of triangle B are interchanged.
So, the coordinates of triangle C are (-5,4),(-2,2) and (-2,4)

What is the constant in the following expression? -8x^2+17y+19
Answer:
(x + 2) • (x - 19)
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 1 • -38 = -38
Step-2 : Find two factors of -38 whose sum equals the coefficient of the middle term, which is -17 .
-38 + 1 = -37
-19 + 2 = -17 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -19 and 2
x2 - 19x + 2x - 38
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-19)
Add up the last 2 terms, pulling out common factors :
2 • (x-19)
Step-5 : Add up the four terms of step 4 :
(x+2) • (x-19)
Which is the desired factorization
Miguel Cabrera had a batting average of 0.33 last season.Mike trout had a batting average of 0.326 during the same season. Who had the higher batting average
Answer:
Miguel cabrera
Step-by-step explanation:
Given that :
Miguel cabrera's batting average = 0.33
Mike trout's batting average = 0.326
The average for both players was obtained during the same season:
Hence. Comparing their respective averages,
0.33 = 0.330
0.330 > 0.326
Hence, Miguel Cabrera's batting average is higher than that of Mike trout

The costs of 1 kg apples and 1 kg grapes are in the ratio of 9:7. The cost of 1 kg apples is Rs 20 more than the cost of 1kg grapes. Find the cost of 1 kg apples and 1 kg of grapes.
Answer:
Apple = Rs90
Grape = Rs70
Step-by-step explanation:
Given
Represent Apples with A and Grapes with G
Such that:
The ratio is
[tex]A : G =9:7[/tex]
And the price is
[tex]A = 20 + G[/tex]
Required
Determine the cost of 1 kg of each fruit
[tex]A : G =9:7[/tex]
Convert to fraction
[tex]\frac{A}{G} = \frac{9}{7}[/tex]
Cross Multiply
[tex]7A = 9G[/tex]
Make A the subject
[tex]A = \frac{9}{7}G[/tex]
Substitute [tex]\frac{9}{7}G[/tex] for A in [tex]A = 20 + G[/tex]
[tex]\frac{9}{7}G = 20 + G[/tex]
Collect Like Terms
[tex]\frac{9}{7}G - G = 20[/tex]
Take LCM
[tex]\frac{9G - 7G}{7}= 20[/tex]
[tex]\frac{2G}{7}= 20[/tex]
Multiply through by 7
[tex]7 * \frac{2G}{7}= 20 * 7[/tex]
[tex]2G= 20 * 7[/tex]
Divide through by 2
[tex]\frac{2G}{2} = \frac{20 * 7}{2}[/tex]
[tex]G = \frac{20 * 7}{2}[/tex]
[tex]G = 10 * 7[/tex]
[tex]G = 70[/tex]
Substitute 70 for G in [tex]A = \frac{9}{7}G[/tex]
[tex]A = \frac{9}{7} * 70[/tex]
[tex]A = 9 * 10[/tex]
[tex]A = 90[/tex]
