Answer:
24x
Step-by-step explanation:
If im seeing the question right
it might be 24x because it looks like you want to multiply 8 by 2 and add 12x.
You'll get 28x and then subtract that by 4x. The answer is 24x.
Answer:
w = 8
Step-by-step explanation:
8w = 64, divide 64 by 8, you get
w = 8
Answer:
H0: u = 0.25 (Null)
Ha: u > 0.25 (Alternate)
Step-by-step explanation:
Hypothesis is written following the rules below:
i) 2 hypotheses are formed in a way that complement of one is claim in the other.
ii) H₀ - the null hypothesis , is the boring hypothesis which claims that things are expected
iii) H₁ -the alternative hypothesis states a claim against null. It always contain the strict inequality signs : less than sign (<), greater than sign (>)and not equal to sign (≠).
Here, we are testing if the mean is less than 0.25 inch
We thus have :
H₀ : u = 0.25 as the null hypothesis and
H₁ : u > 0.25 as the alternative hypothesis
3x - 2y = 13
-2y = -3x + 13
y = 3/2x - 13/2...slope is 3/2, y int is -13/2
2x + 3y = -16
3y = -2x - 16
y = -2/3x - 16/3...slope = -2/3, y int is -16/3
perpendicular lines will have negative reciprocal slopes. To find the negative reciprocal of a number, flip the number and change the sign.
On the 1st equation, the slope was 3/2....find its negative reciprocal.....flip it, making it 2/3....change the sign...making it -2/3. So the negative reciprocal of 3/2 is -2/3.
So if one equation has a slope of 3/2 and another equation has a slope of -2/3, then these lines are perpendicular <==
Answer:
1. 74.6° = m∠C 65.4° = m∠A a = 2.83
2. Triangle does not exist
Step-by-step explanation:
1. Use the law of sines to find m∠C
sin 40/2 = sin C/3
3sin 40/2 = sin C = .96418...
arcsin .96418... = 74.6° = m∠C
m∠A = 180 - 40 - 74.6 = 65.4°
a/sin 65.4 = 2/sin 40
a = 2 sin 65.4/sin 40 = 2.83
2. sin 95/4 = sin C/5
5sin 95/4 = sin C = 1.2452... which is impossible since the cosine of an angle is ≤ 1
