Answer:
2500 pence (C = 2500)
Step-by-step explanation:
[tex]C = 10t + 20m[/tex]
From the given information, t is the number of texts so essentially you will plug in the number of texts provided (150) in the place of the variable t.
[tex]C = 10(150) + 20m[/tex]
Apply the same thing to minutes, plug in the number of minutes (50) in the place of the variable m.
[tex]C = 10(150) + 20(50)[/tex]
Now multiply the substitutes with the co-efficient.
[tex]C = 1500 + 1000[/tex] (10*150=1500 & 20*50=1000)
Add the addends
C = 2500

Using the given discrete probability distribution, it is found that the probability that a randomly selected student has a grade higher than a C is given by:
P(X > 2).
What is the discrete probability distribution for the grade?From the table, it is given by:
P(X = F) = P(X = 0) = 0.04.P(X = D) = P(X = 1) = 0.05.P(X = C) = P(X = 2) = 0.17.P(X = B) = P(X = 3) = 0.31.P(X = A) = P(X = 4) = 0.43.Grades A and B are greater than C, hence the probability of getting a grade higher than C is given by:
P(X > C) = P(X = A) + P(X = B) = P(X = 3) + P(X = 4) = P(X > 2).

a camp having a Ti inmates having food sufficient for 70 days. How many inmates have to leave after 10 days so that the food lasts for another 80 days?
Answer:
20 inmates should leave
Step-by-step explanation:
A camp having 80 inmates, has food sufficient for 70 days.
total=80*70
How many inmates should leave after 10 days so that the
remaining food lasts another 80 days?
the food served for 10 days to 80 inmates
10*80
let x be inmates leave after 10 days food last for 80 days
(80-x)*80
Total=food served for 10 days+x inmates left after 10 days
80*70=10*80+(80-x)*80
70=10+80-x
x=90-70
x=20
A bowl has 8 green grapes and 15 red grapes. Henry randomly chooses a grape, eats it, and then chooses another grape. What is the probability that both grapes are red? about 39.7% about 41.5% about 42.5% about 44.5%
Answer:
About 41.5%
Step-by-step explanation:
Given:
A bowl has 8 green grapes and 15 red grapes. Henry randomly chooses a grape, eats it, and then chooses another grape.
To Find:
What is the probability that both grapes are red?
Answer choices:
about 39.7%
about 41.5%
about 42.5%
about 44.5%
Solution:
Since, there are 8 green grapes and 15 red grapes, the total number of grapes is 23 .
As the red grapes are 15..
Thus,
The probability of choosing a red grape the first time is 15/23.
Because out of the total 23 grapes only 15 were red grape.
The probability of choosing the red grape the second time will be 14/22. Because the number of red grapes has already decreased by one and so is the total number of grapes after first choice
Hence, the probability of choosing or eating two red grapes will be :
15/23×14/22
=105/253
=0.415
= 41.5%
Therefore, the probability that both grapes are red is about 41.5%

Find the arc length of the partial circle.
Either enter an exact answer in terms of \piπpi or use 3.14 π and enter your answer as a decimal.
Answer:
arc = 7.5π units
Step-by-step explanation:
the arc length is calculated as
arc = circumference of circle × fraction of circle
the angle subtended at the centre by the arc is 360° - 90° = 270° , then
arc = 2π × 5 × [tex]\frac{270}{360}[/tex]
= 10π × [tex]\frac{3}{4}[/tex]
= [tex]\frac{30\pi }{4}[/tex]
= 7.5π

We-Haul rents a moving truck for $20.00 and $0.45 per mile. You-Haul rents the same size moving truck for $1.00 per mile but with no upfront charge.
Let c represent the overall cost for renting the moving truck.
Let m represent the miles traveled.
Which of the following statements are true about this situation? Select all that apply.
a
The following equations could be used to represent the situation: c = 0.45m + 20 c = 1.00m
b
The y-intercepts of each line represent the upfront charge to rent the moving truck.
c
At 38 miles, We-Haul would be a better deal.
d
The two truck rentals will cost the same around mile 35.36
e
The rate of change for You-Haul is larger than the rate of change for We-Haul
Answer:
*select all that apply*
All of these are true
Step-by-step explanation:
Answer choice A:
We-Haul: c = 0.45m + 20
You-Haul: c = 1m
--> TRUE
Answer Choice B:
the y-intercept is the upfront charge bc the charge for "per mile" is attached to "mx" and the "b" (y-intercept) is the upfront charge
--> TRUE
Answer choice C:
We-Haul -
c = 0.45(38) + 20 = $37.10
You-Haul -
c = 1m = $38.00
--> TRUE
answer choice D:
We-Haul -
c = 0.45(35.36) + 20 = $35.91
You-Haul -
c = 1m = $35.36
Since the two costs are very close to being the same, I think this is a true statement also
--> TRUE
Answer choice E:
You-Haul's rate is 1 mph whereas We-Haul's rate is 0.45mph. You-Haul's rate is 0.55 larger than We-Haul's
--> TRUE
Hope this helps :)

What is the total area of the figure? (square inches)
Answer:
60
Step-by-step explanation:
TOTAL SURFACE AREA = AREA OF SQUARE+2×(AREA OF TRIANGLE)
=(6×6)+2×(1/2×6×4)
=36+24=60 square inches
I hope it helped you
Answer:
The area of the full figure is 60 square inches.
Step-by-step explanation:
There are 4 triangles and one square in this figure. We can start by figuring out the area of the middle square, which would be [tex]6*6=36[/tex] because we know the sides are all 6 inches.
Next, we can look at the triangles and see that their hypotenuses (the longest sides) are all the same length, that being 5 inches. This means that we only need to find the length of the third side and then multiply the area of one triangle by 4 to get the area of all the triangles.
The pythagorean theorem states that in any right triangle, [tex]a^2 +b^2=c^2[/tex], with [tex]c^2[/tex] being the length of the hypotenuse. Since we know the length of the hypotenuse is 5 and one of the legs of the triangle is 4, we can insert this into the equation: [tex]a^2+4^2=5^2[/tex], which when simplified all the way gives us that [tex]a=3[/tex].
Since a right triangle is half of a rectangle, the easiest way to find the area of the triangle is to multiply the measures of the two legs together and then divide by two: [tex](3*4)/2=6[/tex]. Therefore, we know that each triangle in the picture has an area of 6.
Finally, you need to add all of the areas together to find the area of the full figure: [tex]36+6+6+6+6=60 in^2[/tex]
The area of the full figure is 60 square inches.
Hope this helps! :)

a – 16 = 24 simple equation
Answer:
40
Step-by-step explanation:
16+24=40
40-16=24
Answer:
a = 40
Step-by-step explanation:
Add 16 on both sides
a - 16 + 16 = 24 + 16
a = 24 +16 = 40
a = 40
Verification
LHS = a - 16 a = 40
40 - 16 = 24
RHS = 24
Both LHS and RHS are same so, our answer is correct.

Solve 169x2 − 16 = 0 by using square roots.
A. ±13/4
B. ±169/16
C. No solution
D. ±4/13
Answer:
Option D, [tex]x =[/tex] ± [tex]4/13[/tex]
Step-by-step explanation:
Step 1: Add 16 to both sides
[tex]169x^2 - 16 = 0[/tex]
[tex]169x^2 - 16 + 16= 0 + 16[/tex]
[tex]169x^2 = 16[/tex]
Step 2: Divide 169 from both sides
[tex]\frac{169x^2}{169} = \frac{16}{169}[/tex]
[tex]x^2 = 0.09467[/tex]
Step 3: Square root both sides

What is the median number of words in Darcy's essays?
Answer:
210.8 (mean for Luis), 241.5 (mean for Darcy)
Step-by-step explanation:
Luis 178 + 213 + 198 + 245 + 236 + 198 + 221 + 253 + 189 + 177 = 2108
2108/10 = 210.8 (mean for Luis)
Darcy 231 + 210 + 245 + 259 + 286 + 245 + 231 + 244 + 236 + 228 = 2415
2415/10 = 241.5 (mean for Darcy)
Answer:
To find the median number of words in Darcy’s essays, first arrange the values in the data set in ascending order:
210, 228, 231, 231, 236, 244, 245, 245, 259, 286.
Because the number of values in the data set is an even number (10), the median is the mean of the two middle values, the fifth and sixth values, in the data set. The fifth and sixth values are 236 and 244, respectively. So,
median
.
The median number of words in Darcy's essays is 240.

Joe has a rectangular prism made of aluminum and a rectangular prism made of lead.
Each rectangular prism has a height of 6 cm, length of 9 cm, and width of 3 cm.
