Evaluate C(7,5) please
Answer: 21
Step-by-step explanation: This is a combination of 7 objects taken 5 at a time
nCr = n! / r! * (n - r)!
7C5 = 7! / (5! (7-5)!)
= 7! /(5! 2!)
= (7*6*5*4*3*2*1)
-----------------------
5*4*3*2*1 * 2*1
Canceling
= 7*6/ (2*1)
= 21
g The tensile 0.2 percent offset yield strength of AISI 1137 cold-drawn steel bars up to 1 inch in diameter from 2 mills and 25 heats is reported as follows: S y 93 95 97 99 101 103 105 107 109 111 f 19 25 38 17 12 10 5 4 4 2 where y S is the class midpoint in kpsi and f is the number in each class. Presuming the distribution is normal, what is the yield strength exceeded by 99 percent of the population
Answer:
107.50
Step-by-step explanation:
Given the following :
Midpoint (S)____F
S y 93 95 97 99 101 103 105 107 109 111 f 19 25 38 17 12 10 5 4 4 2
Calculating the mean and standard deviation using a calculator :
The mean(m) of the data above = 98.12
Standard deviation (sd) = 4.02
Proportion = 99% of population
From z table = 2.33
Using :
Zscore =(x - m) / sd
2.33 = (x - 98.12) / 4.02
2.33 * 4.02 = x - 98.12
9.3666 = x - 98.12
9.3666 + 98.12= x
x = 107.4866
X = 107.50

Answer:
20cm
Step-by-step explanation:
A=hb/2
h=5cm
b=8cm
A=(5*8)/2
A=40/2
A=20
Answer:
48 cm^2
Step-by-step explanation:
A. 1 triangle
1. Simplify the base:
8cm + 8cm = 16 cm
2. Use the formula to solve:
A = 1/2 bh
A = 1/2(16)(6)
A = (8)(6)
A = 48

So, what is 2/5 of 15? It's 6
so 5+6=11
11/15
and reduce
so 2 1/5

Step-by-step explanation:
A motorcyclist is riding along a mountain trail that runs parallel to a road below. In fact the trail is 6 meters above the road. The motorcyclist then notices a flat bed truck directly below moving at the same speed and decides to drive off the trail, without changing speed. Fortunately, the motorcycle safely lands on the flatbed of the truck. What would the outcome have been if the trail was 12 meters above the road, but all other parameters remain the same?
Answer:
The motorcycle would still land on the truck FLATBED just the way it landed when the trail was 6 meters above the road.
Step-by-step explanation:
Based on the information given about the motorcyclist we were told that the trail was 6 meters above the road in which despite that the motorcyclist drive off the trail without changing his motorcycle speed which made the motorcycle to land on the truck FLATBED which means that if the trail was 12 meters above the road while all other parameters remain the same what the outcome could have been is that the motorcycle would still land on the truck FLATBED just the way it safely landed when the trail was 6 meters above the road.
Therefore FLATBED truck can simply be defined as truck which does not have any thing covering both the right side and left side of truck and as well does not have roof making the truck to have a FLATBED or flatbody which is why most of this type of truck are mostly used to transport goods or loads that are heavy.

x=16
Write the three forms of the line parallel to the line represented by the equation, 8x+3y=11 such that it passes through the point (9, -5).
Answer:
8x + 3y = 57y = -8/3x + 19y + 5 = -8/3(x - 9)Step-by-step explanation:
Given function
8x+3y=11Line parallel to the given has the same slope and passes through the point
(9, -5)Determining the equation
8x + 3y = c8*9 + 3*(-5) = cc=72 - 15c = 57So the function is in standard form
8x + 3y = 57Converting to slope-intercept form
y = mx + b3y = -8x + 57y = -8/3x + 573y = -8/3x + 19Point-slope form, using the given point
y - y1 = m(x - x1)y - (-5) = -8/3(x - 9)y + 5 = -8/3(x - 9)What is the sum of 7/12 + 4/5

Step-by-step explanation:

Denominator stays the same
Answer:
1/3
Step-by-step explanation:
when adding and subtracting fractions you need to make sure there is a common denominator (same number on the bottom of the fractions). luckily these fractions already have that so you just add them! when they have a common denominator the number stays the same. so 3+3 in this equals 3 lol

Frank rented a truck for one day. There was a base fee of $16.99, and there was an additional charge of 76 cents for each mile driven Frank had to pay
$228.27 when he returned the truck. For how many miles did he drive the truck?
miles
Answer:
267
Step-by-step explanation:
Answer: He drove the truck for 278 miles.
Step-by-step explanation:
We can represent the situation by the equation, 16.99 + 0.76x = 228.27 where x is the number of miles. 16.99 is the base fee an 0.76 is the same as 76 cents .
Solve for x in the equation to find out how many miles was driven.
16.99 + 0.76x = 228.27
-16.99 -16.99
0.76x = 211.28
x= 278

200 bottles of equal capacity hold 350 liters of water .How much does each hold?
Answer:
SECRET HAHAHAHHA
Step-by-step explanation:
Answer:
1.75 liters
Step-by-step explanation:
We know that all 200 bottles can hold 350 liters of water.
Suppose each bottle holds b liters of water. Then we can model the situation in terms of b:
200b = 350
Divide both sides by 200:
b = 350/200 = 35/20 = 1.75
The answer is thus 1.75 liters.
