Answer: Number from 1 through 50. 50 possible numbers. multiple of 10 : 10, 20, 30, 40, 50. 5 possible events. multiple of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48. 12 possible events one-digit number: 1, 2, 3, 4, 5, 6, 7, 8, 9. 9 possible events P(multiple of 10) = 5/50 or 1/10 P(not 100) = 50/50 or 1 P(not a multiple of 4) = 38/50 or 19/25 P(one-digit number) = 9/50
Answer: See below
Step-by-step explanation:
Test 1:
5 numbers that are a multiple of 10
Total amount of numbers = 50
Probability = 10/50
P = 1/5 or 20%
Test 2:
None of the numbers from 1 to 50 are 100, so obviously the probability will be 1 or 100%
Test 3:
12 multiples of 4 in all 50 numbers, since we want numbers that are not multiples of 4 we subtract the total number of them from 50
50 - 12 = 38
Probability = 38/50
P = 19/25 or 76%
Test 4:
There are 9 one-digit numbers in total
Probability = 9/50
P = 9/50 or 18%
Problem 1: Consider the (nonlinear) differential equation
[tex]y' = \frac{ - y(y + 1)}{x} [/tex]
Without solving the equation, check which of the following are solutions:
[tex]y(x) = {x}^{2} - 1[/tex]
[tex]y(x) = \frac{2}{x - 2} [/tex]
That is: do not use the method of integrating factors to solve. Just check by plugging in.
If y = x² - 1, then y + 1 = x² and y' = 2x. Then in the DE, we would have
2x = - (x² - 1) x² / x ⇒ 2 = - x² + 1
but this only true for some values of x. So the first choice is not correct.
If y = 2/(x - 2), then y + 1 = x/(x - 2) and y' = -2/(x - 2)². In the DE,
-2/(x - 2)² = - (2/(x - 2)) (x/(x - 2)) / x ⇒ -2/(x - 2)² = -2/(x - 2)²
so the second choice is the correct answer.
y = (?) 25°, 30° Please Help
Answer: if you’re asking for the missing angle then it’s 125°
Step-by-step explanation:
triangles always equal 180°
i’m assuming 25° and 30° are the other angle measures so
25° + 30° = 55°
180° - 55° = 125°
so the missing angle is 125°
hope this helps :)
Which of the following number line graphs shows the solution set of 3|x| + 1 > 7?
Answer:
D
Step-by-step explanation:
When doing this problem remember that absolute value is a number's distance from zero, and distance is always positive. So, absolute value makes any number positive. This means that |±x| = x. To find the correct number graph, first solve the inequality.
3|x| + 1 > 7Subtract 1 from both sides
3|x| > 6Divide both sides by 3
|x| > 2Then, we need to use absolute value. Any number with a distance from 0 greater than 2 fulfills this inequality. So, the number graph should represent -2 > x and x > 2. Additionally, because the inequality is looking for greater than but not equal to, the circles should be open.

Mattie Evans drove 200 miles in the same amount of time that it took a turbopropeller plane to travel 950 miles. The speed of the plane was 150 mph faster than th
speed of the car. Find the speed of the plane.
The speed of the plane was mph.
(Simplify your answer.)
Answer:
speed of the plane = 190 mph
Step-by-step explanation:
Let x = speed of the plane, then speed of the car = x - 150
time = 200/(x - 150) = 950/x
Divide by 50 on both sides, get
4/(x - 150) = 19/x
Cross multiply:
4x = 19(x - 150)
4x = 19x - 19*150
15x = 19*150
x = 19*150/15 = 190

Answer:
85 km
Step-by-step explanation:
to find this answer you must use the pythagorean theorem
this formula is basically a^2 + b^2 = c^2
so square the two sides that you have and thats the answer of the hypotenuse squared
68^2 + 51^2 = c^2
4624 + 2601 = 7225
then you must take 7225 to the square root
that is 85

A high school championship football game was attended by 1,580 fans. There were 640 were out-of-state fans at the game. The other fans who attended were local.
Which statement is TRUE when interpreting the ratio of out-of-state fans attending the game to the total number of fans attending? A) 32 out of every 79 fans attending were out-of-state fans B) 47 out of every 79 fans attending were out-of-state fans C) more than 47 out of every 79 fans attending were out-of-state fans D) at least 32 out of every 79 fans attending were out-of-state fans
Answer:
A)
Step-by-step explanation:
total number of fans = 1580out of state fans = 640local fans = total number of fans - out of state fans = 1580 - 640 = 940ratio of out of state fans to total number of fans:
640 : 1580 = 640/1580 = 32/79
So 32 out of every 79 fans were out of state fans
Answer:
A) 32 out of every 79 fans attending were out-of-state fans
Step-by-step explanation:
640 were out-of-state fans : 1,580 fans in the game
32 were out-of-state fans : 79 fans in the game
✔A) 32 out of every 79 fans attending were out-of-state fans
B) 47 out of every 79 fans attending were out-of-state fans
C) more than 47 out of every 79 fans attending were out-of-state fans
D) at least 32 out of every 79 fans attending were out-of-state fans

P(X) 0.191

Which graph correctly displays this probability distribution?
Probability distributions can be represented using tables and graphs
How to determine the graphThe probability table is given as:
x 0 1 2 3 4
P(x) -> 0.191 0.319 0.287 0.128 0.074
The above table means that:
P(0) = 0.191
P(1) = 0.319
P(2) = 0.287
P(3) = 0.128
P(4) = 0.074
Next, we check if the table represents a probability distribution using:
[tex]\sum P(x) = 1[/tex]
So, we have:
[tex]\sum P(x) = 0.191 + 0.319 + 0.287 + 0.128 + 0.074[/tex]
[tex]\sum P(x) = 1[/tex]
The graph is not given. So, I will plot the graph

Answer:
ZX = 30 unitsStep-by-step explanation:
Since the triangles are similar, the ratio of corresponding sides are same.
ZX is the largest side and corresponding side is BC = 60, the shortest sides are BC = 40 and YZ = 20:

Step-by-step explanation:
Answer:
3,694.71 dollars
Step-by-step explanation:
Given the following question:
Dora earns a monthly salary of $3,568...
She also earns a 1% commission...
Last month she sold $12,674 worth of products
To find the answer we have to find 1% of her last month's pay and then add that number to her monthly salary.
1% of $12,674
[tex]\frac{1\times12674}{100} =1\times12674=12674\div100=126.74[/tex]
1% of $12,674 is $126.74
[tex]3568+126.71=3694.71[/tex]
The number is already rounded to the nearest hundredth's place.
[tex]=3694.71[/tex]
So, in total Dora earns "$3,694.71" for last month.
Hope this helps.
