Answer:
The width of member is as follows:
b = 3 ft
b = 3 × 12 in.
b= 36 in.
The depth of member is as follows:
d = 8 ft
d = 8 × 12 in.
d=96 in.
Since the structure used is Douglas fir-Larch lumber of size 3 × 8 size. Hence, tensile strength, f =1000 psi
Calculate the net area of the member as follows:
A = (b - ∅) × d
A= (36 - 7/8) × 96
Calculate the maximum axial tensile load by ASD method as follows:
P = f × A
P = 1000 x 3372
P = 3372000 lbs
P = 3372 kips
Answer:
1.) C. 32
2.) Stem-and-leaf plot
Step-by-step explanation:
This is a stem-and-leaf plot. The stem represents tens and the leaves represent units. To make it easier to look at, it is equivalent to this:
- 20, 28, 29, 29, 31, 32, 36, 41, 42
Now, to find the mean, add up all the numbers and divide the sum by the number of values.
(20 + 28 + 29 + 29 + 31 + 32 + 36 + 41 + 42)/9 = 288/9 = 32
Answer:
192
Step-by-step explanation:
to find the mean you have to use this formula: mean= N(total number of trials) times P( probability of "success")
n=640
p=0.3
640x0.3= 192
So the ratio of the first engine is 4 gasoline: 1 oil. 4:1 ratio. So the question is asking __ gasoline: 5 oil? Simple. For every 1 part of oil is 4 parts gasoline, so for the answer, you'd cross multiply.
Answer:
16J(5exponent)K(3exponent)
First times the two numbers (4 x 4) which equals 16. And then J doesn't have an exponent but it automatically has one as it's exponent. So the other parenthesis has J with 4, just add the 4+1 and that equals 5 so that gives you 5 as the exponent. There isn't a K for the second parenthesis so you just leave it as k( 3 exponent)
