A jar has 4 red marbles 7 blue marbles and 8 yellow marbles what is the probability of randomly selecting a marble and getting a blue marble?
Please help!!!!
Explanation:
There are 7 blue marbles out of 4+7+8 = 11+8 = 19 total
The probability of selecting blue is therefore 7/19
We cannot reduce 7/19 any further because 7 and 19 have no common factors other than 1.
Find the slope of the line containing the pair of points. (7,4) and (6,-9)
Answer:
13
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( -9-4)/(6-7)
= -13/-1
= 13

Step-by-step explanation:
r = 32/40 = 0.8
S10 = 40(1- (0.8)^10)/ (1- 0.8)
= 40(1 - 0.107) / 0.2
= 200(1.107)
= 221

On a field trip, the ration of students who brought a water bottle to those who didn’t was 7 to 4. If 60 students did not bring water bottle, determine the total number of students on the field trip.
Answer:
165 students
Step-by-step explanation:
7/4 = x/60
(60*7)/4 = 105
105 + 60 = 165
PLS HELP!!! Which of the following function graphs have a range of (-∞, ∞)?
Answer:
b
Step-by-step explanation:
Please help ASAP thank you
Answer:
A) a = 25
B) b = 14
Step-by-step explanation:
hopefully this helps :)
Solve the following:
[tex] \\ \sf \: a) \: \: \frac{a}{5} + 3 = 8[/tex]
[tex] \\ \sf \: b) \: \: \frac{3b}{7} - 1 = 5[/tex]
Solution:-Solving question a) :
[tex] \\ \sf \frac{a}{5 } + 3 = 8[/tex]
[tex] \\ \sf \mapsto \frac{a + 15}{5} = 8[/tex]
[tex] \\ \sf \mapsto \: a + 15 = 8 \times 5[/tex]
[tex] \\ \sf \mapsto \: a = 40 - 15[/tex]
[tex] \\ \sf \mapsto \: a = 25[/tex]
[tex] \\ \sf \therefore \: a = 25[/tex]
Solving question b) :
[tex] \\ \sf \frac{3b}{7} - 1 = 5[/tex]
[tex] \\ \sf \mapsto \: \frac{3b - 7}{7} = 5 [/tex]
[tex] \\ \sf \mapsto3b - 7 = 5 \times 7[/tex]
[tex] \\ \sf \mapsto3b = 35 + 7[/tex]
[tex] \\ \sf \mapsto \: b = \frac{42}{3} [/tex]
[tex] \\ \sf \mapsto \: b = 14[/tex]
[tex] \\ \sf \therefore \: b = 14[/tex]
Answer:-a = 25
b = 14

Step-by-step explanation:
-2x+21
x=6 -12+21 = 9
x=7 -14+21 =7
x=8 -16+21 = 5

Can you y’all help me with this. i need to know what is the domain and range from this graph. i’m kinda confused for this
Answer:
The answer is below:
Step-by-step explanation:
The range is everything under and including 6 as we see that it will forever go to numbers under or equal to 6.
The range is all real because the lines will keep on going to infinity and negative infinity
Domain: All Real
Range: y is greater than or equal to 6

Help plssssss I love yall sooooo much just please help btw this is Math just try your best love yallllllll!!!!!!!!
help asap plsssssssssssssssssssssssssss. Find the missing parts of each number line. Assume that the lines have been split into equal parts.
Answer:
16 for the first one. each segment is 4
40 for the second. each segment is 8
Answer:
0, 4, 8, 12, 16
8, 16, 24, 32, 40, 48
Step-by-step explanation:
The first number line has 6 parts. 24÷6=4. Each vertical line will increase by 4.
So starting at 0, the parts of the number line are:
0, 4, 8, 12, 16, 20, 24
The specific part being asked for is 0, 4, 8, 12, 16
The second number line has 8 parts. 64÷8=8. Each vertical line will increase by 8.
Starting at 0, the parts of the number line are:
0, 8, 16, 24, 32, 40, 48, 56, 64
The specific part being asked for is 8, 16, 24, 32, 40, 48

Which equation matches the graph of the greatest integer function given
below?
Answer:
D. y = [x] - 2
Explanation:
The Greatest Integer Function is denoted by y = [x].
For all real numbers, x, the greatest integer function returns the largest integer less than or equal to x. In essence, it rounds down a real number to the nearest lowest integer.
In the plot of y = [x], the plot starts from origin because y = [0] = 0.
But, in the question, all the lines are shifted 2 units downward, as it starts from (0, -2).
i.e for every values of x, y moves two units down
So our answer is y = [x] - 2.
(Information reworded from "InesWalston" who is another user on Brainly when they responded to the same question!)
Hope this helps, good luck! :D
[ SIDE NOTE: Someone else said that it is y=[x]-4, so I am not 100% sure! ]

the quadratic x2-4x-21 can be witten in the form (x+a)2 +b find the values of a and b
(x-2)^2-25
How?
[tex]\\ \sf\longmapsto (x-2)^2-25[/tex]
[tex]\\ \sf\longmapsto x^2-4x+4-25[/tex]
[tex]\\ \sf\longmapsto x^2-4x-21[/tex]
Answer:
a = - 2, b = -25Step-by-step explanation:
Given quadratic expression:
x² - 4x - 21Convert this into vertex form:
x² - 4x + 4 - 25 = (x - 2)² - 25Compare this with the vertex form to determine the values of a and b:
a = - 2b = -255. Geometry A rectangular vegetable garden has a length of 8 ft and a width of 5 ft. The width is increased by 2 ft. By how many square feet does the area increase?
Amanda recorded the temperatures at which two oils freeze:

A Peanut oil freezes at a lower temperature than olive oil because 3.1 °C < −6.1 °C.
B Peanut oil freezes at a higher temperature than olive oil because 3.1 °C < −6.1 °C.
C Peanut oil freezes at a lower temperature than olive oil because 3.1 °C > −6.1 °C.
D Peanut oil freezes at a higher temperature than olive oil because 3.1 °C > −6.1 °C.
Answer:
It's C, Peanut oil freezes at a lower temperature than olive oil because 3.1 > -6.1

Answer:
5 five dollar and 7 one dollar
Step-by-step explanation:
let the number of one dollar be xthe number of five dollar be y1x+5y=32
x+y=12
using elimination method
+x-x-y+5y-32+12=0
4y-20=0
4y=20
divide both side by 4y=20/4 =5
so, if. y is 5 then x is
5y+x=32
5(5)+x=32
25+x=32
x=32-25
x=7
