Answer:
3 hours
Step-by-step explanation:
275+55 t=440
55 t=440-275
or 55 t=165
t=165/55=3
Answer:
92.616%
Step-by-step explanation:
Given is the data of x and y where
x = current density (mA/cm2) and
y = rate of deposition (µm/min)
to find out whether there is linear relationship between x and y
x y
20 0.14
40 1.25
60 1.71
80 2.07
r 0.962364513
r^2 0.926145457
Since r is very near to 1, we find that there is a strong positive correlation and hence linearity can be assumed
r square the coefficient of determination is 0.9261 which is 92.616%
this is the measure which accounts for variation in x due to y and or variation in y due to x.
If he attempted 45 passes, find how many passes he completed. Round to the nearest whole number of necessary.
Answer:
VW = 4 cm
Step-by-step explanation:
Congruent chords are equidistant from the centre , so
VW = UV = 4 cm
The table of the relative frequencies show that <u>70% of 8th graders</u> want the water slides.
There is an association between grade level and field trip choice with the higher grades preferring Water slides more than roller skating.
9th graders would prefer waterslides if the trend continues.
<h3>What does the frequency table show?</h3>
The percentage of 8th graders who want to go to water slides is:
= 0.14 / 0.20 x 100%
= 70%
As the grades increase, less people want to go roller skating which means that should this trend continue, 9th graders would prefer water slides.
