Answer:
A=50 B=40 C=90
Step-by-step explanation:
B is a right angle so its automatically 90 degrees since A=50 and a triangle has to be 180 degrees 90+50= 140, 180-140=40.
Errrmmm.... Where is the expression?
6.25 is the answer to the problem
Answer:
73.1 inches
Step-by-step explanation:
We solve for this using z score formula.
z-score is z = (x-μ)/σ,
where x is the raw score,
μ is the population mean
σ is the population standard deviation.
x = unknown = randomly selected male's height
μ = 70.3 inches
σ = 4.1 inches
z = is not given but we are given its percentile which is 75
The z score for a 75th percentile = 0.674
Hence,
0.674 = x - 70.3/4.1
Cross Multiply
0.674 × 4.1 = x - 70.3
2.7634 = x - 70.3
x = 70.3 + 2.7634
x = 73.0634 inches
The height of the randomly selected male = 73.0634
Therefore, the height of the randomly selected male to the nearest tenth of an inch is 73.1 inches
Answer:
18x+y=-52
Step-by-step explanation:
we all know and love(being 100% sarcastic here)the standard form as
ax+by=c
y=-9(x+3)*2+2----This is weird and not so nice
so lets make it nice by distributing the 9::::
y=(-9x-27)2+2
and now the 2:
y=-18x-54+2
y=-18x-52
oops this is NOT in S.F we got to switch the -52 and y
52=-18x-y
-18 cant be neg. so we have to divide by -1 on both sides
-52=18x+y
18x+y=-52
HOPE THIS HELPS
