Arc AB is 72, Arc AC is 120, Arc BC is 168, Angle A is 84, Angle B is 60, Angle C is 36
Step-by-step explanation:
Got it off Delta math, I got this question wrong and I ain’t want y’all to feel my pain So here u go
5.40/x=0.75/1
cross multiply:
0.75x=5.40
divide:
0.75x/0.75=5.40/0.75
x=$7.20
just to check:
5.40/3=1.8
1.8*4=7.2
the answer is $7.20 for 1 hour
Answer:
y = 5/6 x - 35/6
Step-by-step explanation:
first convert equation to y = mx + b to get the slope
5x -7 = 6y
5/6 x - 7/6 = y
5/6 is the slope
because the line is parallel, the slope is 5/6
use the point given and simplify
y + 5 = 5/6 (x - 1)
y + 5 = 5/6x - 5/6
y = 5/6x - 5/6 - 30/6
y = 5/6x - 35/6
Answer:
The temperature for P 84 is approximately 1ºC.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
Assume that the readings on the thermometers are normally distributed with a mean of 0 degrees and standard deviation of 1.00°C. This means that
and 
This is the temperature reading separating the bottom 84 % from the top 16 %.
This temperature is the value of X when Z has a pvalue of 0.84. This happens at
.
So



The temperature for P 84 is approximately 1ºC.
