Answer: The probability that Jo is not late on Monday = 0.6
Step-by-step explanation:
The probability of getting late is independent on each day.
Also, for an event E
Probability of not E = 1- P(E) , where P(E) = Probability of happing E
Given: The probability Jo is late on a Monday is 0.4.
Then, the probability that Jo is not late on Monday = 1-0.4= 0.6
Hence, the probability that Jo is not late on Monday = 0.6

Answer: (9,7)
Step-by-step explanation:
What is the slope of the line shown below?
Answer:
B. 4
Step-by-step explanation:
Slope = (-2-6)/1-3) = = - 8/ - 2 = 4
Answer:
C. 4
Step-by-step explanation:
slope = (y2 - y1)/(x2 - x1)
slope = (-2 - 6)/(1 - 3)
slope = -8/(-2
slope = 4

Diagram shows the composite solid formed by a cuboid and a right prism. Trapezium LMNP is the uniform cross section of the prism. It is given the volume of the composite solid is 444cm³. Calculate the length, in cm of MN
Answer:
MN = 7 cm
Step-by-step explanation:
Well the volume we can separate into pieces
first the ABCDEFGH (? you know this cuboid)
which has a volume of
[tex]V = AB\cdot BC\cdot CH\\\\V = 3*6*(3+JY+4)[/tex]
if you ask where does the 4 come from
it comes from LP = KB = YC and JY + YC =JC
so
[tex]V = 18(7+MX)[/tex]
this is because JY = MX
the other volume is of BCNPKLXY (hope you understand which one)
and the volume is
[tex]V = BP*PN*NX\\\\V=8*6*4\\\\V = 192[/tex]
and the last one is KYXLMJ (the top "triangle")
the volume is
[tex]V = \frac{LX*XM}{2}*LK\\\\V = \frac{6*MX}{2}*8\\\\V= 6*4*MX\\\\V=24MX[/tex]
so now add them up
and has to equal 444
[tex]V_T = 18(7+MX)+192+24MX\\\\V_T = 126+18MX+192+24MX\\\\V_T = 318+42MX\\\\444=318+42MX\\\\444-318=42MX\\\\126=42MX\\\\MX = 3[/tex]
and finally we know that MN = MX + XN = 3+4 = 7
so here is our answer MN = 7 cm
a couple of notes
[tex]1.\:\angle LXM = 90\\\\2.\:\angle KYX = 90[/tex]
3. the units don't matter due to the fact that everything is in cm
4. see the picture below to get a better idea of which prism I am talking of
5. tell me if you have questions :D

david earns $1.50 per hour more than peter. together, they earn $940 if they both work 40 hours in a week. how much money per hour do david and peter earn?
Answer:
469.25
Step-by-step explanation:
peter=x
david=x+1.50
x+(x+1.50)=940
x=940-x-1.50
2x=940-1.50
2x=938.5
x=938.5/2
x=469.25

You are buying ribbon to make costumes for a school play. Organza ribbon costs $.07 per yard. Satin ribbon costs $.04 per yard. Write an equation to model the possible combinations of yards of organza ribbon and yards of satin ribbon you can buy for $5. List several possible combinations.
Answer:
Let's define the variables:
x = yards of Organza ribbon that you buy.
y = yards of Satin ribbon that you buy.
We know that the price per yard of Organza ribbon is $0.07, this means tat if you buy x yards, the cost will be:
C = x*$0.07
And the cost of the Satin ribbon is $0.04, so if you buy y yards of that ribbon, the cost will be:
C = y*$0.04
Adding that together, the total cost is:
C = x*$0.07 + y*$0.04
Now we know that you pay $5, this means that the total cost is exactly $5, then we have the equation:
$5 = x*$0.07 + y*$0.04
Now we can isolate the variable y to get:
y = ($5/$0.04) - x*($0.07/$0.04)
y = 125 - x*1.75
Now we can just input different values of x to find the correspondent value of y.
This means that:
if x = 0 (0 yards of the Organza ribbon)
then:
y = 125 - 0*1.75 = 0
This combination is:
0 yards of organza, and 125 yards of satin.
Now, if x = 20, then:
y = 125 - 20*1.75 = 90
This combination is:
20 yards of organza, and 90 yards of satin.
if x = 40, then:
y = 125 - 40*1.75 = 55
This combination is:
40 yards of organza, and 55 yards of satin.
The 3 combinations that we found cost exactly $5.
Mrs. Andrews has 10 pink and 7 orange markers. Which ratio compares the number of pink markers to the number of orange markers?
Answer:
7/10
Step-by-step explanation:
The ratio 10:7 represents the number of pink markers to the number of orange markers.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
Total number of pink Mrs. Andrews has = 10
Total number of orange Mrs. Andrews has = 7
The ratio of number of pink markers to the number of orange markers:
= 10:7
Thus, the ratio 10:7 represents the number of pink markers to the number of orange markers.

A line, L, has the equation y = 5x – 1.
Write down the gradient of line L.
Answer:
5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope (gradient) and c the y- intercept )
y = 5x - 1 ← is in slope- intercept form
with gradient = 5
is 7.5 a even or odd number?
Answer:
Only Integers are considered even or odd. So this is not possible to solve. But if you HAD to choose, I believe that it will be even because you round up then its 8 and there you have a even number
