Answer:
m = 18
Step-by-step explanation:
In an arithmetic progression, the middle term of three is half the sum of the terms on either side.
a1 +a3 = 2(a2)
(m +9) +(2m +7) = 2(2m -1)
3m +16 = 4m -2 . . . . . . collect terms
18 = m . . . . . . . . . . . . . . add 2-3m
pls help anyone!! i don’t know the answers :(

Step-by-step explanation:
If there is 10 fruits and 3 of them are pears
10x 12= 120
3x12 = 36
Answer:
Step-by-step explanation:
all the fruits are 10
the pears are 3
probability of picking a pear is 3/10
out of 120 times the pear may be picked 120*(3/10) = 36 times
What is the surface area of the prism?
Step 1: Find the area of the bases (triangles)
A = 1/2 * base * height
A = 1/2 * 16 * 6
A = 48
48 + 48 = 96
Area of the triangles = 96 cm^2
Step 2: Find the area of the sides (rectangles)
A = base * height
A1 = 16 * 12
A1 = 192
A2 = 10 * 12
A2 = 120
120 + 120 = 240
240 + 192 = 432 cm^2
Step 2: Add the areas together
96 + 432
528 cm^2
Hope this helps!! :)
A camera company sells two types of Point and Shoot cameras. Model A costs $150 and Model B costs $225. If the company sold 22 cameras for a total $3900 last month, how many of each model were sold? PLEASE HELP ASAP!!
Answer:
A=14 and B= 8
Step-by-step explanation:
the equation systems:
150A + 225B = 3900
=> 6A + 9B= 156 .... (1)
A + B = 22 ..... (2)
<=> 6A + 9B = 156
6A + 6B = 132
_____________-
3B = 24
B= 8 and A = 22-8 = 14
find the hcf and the lcm of these for 10 points plz
Answer:
LCM of 64 and 94= 3008
HCF of 64 and 94= 2
Step-by-step explanation:
Do a venn diagram with the prime factors of 64 on the left, and the prime factors of 94 on the right. If they have the same factors put them in the middle of the venn diagram. Then you multiply everything in the diagram and get the LCM. The HCF is found by multiplying the factors in both lists which is only 2.

Is ΔABC ~ ΔDEF? Explain. Triangle A B C has angle measures A 18 degrees, B 110 degrees, and C unknown. Triangle D E F has angle measures D 52 degrees, E 18 degrees, and F unknown.
9514 1404 393
Answer:
no
Step-by-step explanation:
Triangle ABC has angle measures ...
A = 18°B = 110°C = 180° -18° -110° = 52°Triangle DEF has angle measures ...
D = 52°E = 18°F = 180° -52° -18° = 110°Using the angle measures in the order 18, 110, 52, we can write the similarity statement as ...
ΔABC ~ ΔEFD
The similarity statement given in the problem is incorrect. ΔABC is not similar to ΔDEF.

The average number of employees that call in sick for the day over the course of a year is 25. The number of employees that call in sick on 12 days are 25, 10, 16, 39, 27, 25, 32, 25, 25, 22, 28, and 14. Enter the sample mean and the population mean in the boxes
Answer:
sample mean (x with the bar on top) =24
Step-by-step explanation:
Take the mean of all the number of employees but divide by the number of days size: (25+10+16...)/12=25
population mean (mu) =11.52
The same goes for the other one but divide by the population which is 25

Answer:
A) it depends. If they bought 10 calculators, we would multiply 31.25 by 10. 31.25x10=$312.50
B)Divide 500 by 31.25. Since each calculator is $31.25, we divide $500 by it to see how many they can buy with $500. 500/31.25=16

how do you solve the problem 2p = 60
in a group of 35 children, 10 have blonde hair, 14 have brown eyes, and 4 have both blonde hair and brown eyes. if a child is selected at random, find the probability that the child has blonde hair or brown eyes
[tex] \frac{14}{35} + \frac{10}{35} - \frac{4}{35} = \frac{4}{7} [/tex]
The solution is, 4/7 is the probability that the child has blonde hair or brown eyes.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
here, we have,
given that,
in a group of 35 children, 10 have blonde hair, 14 have brown eyes, and 4 have both blonde hair and brown eyes.
let, the event be A,
i.e. A = if a child is selected at random, that child has blonde hair or brown eyes.
now, we have,
total no of sample space = 35
probability of blonde hair = 10/ 35
probability of brown eyes = 14/35
probability of both blonde hair and brown eyes = 4/35
so, we get,
probability of blonde hair or brown eyes = 14/ 35 + 10/ 35 - 4/35
= 20 / 35
= 4/7
Hence, The solution is, 4/7 is the probability that the child has blonde hair or brown eyes.
