Answer:
Below.
Step-by-step explanation:
This is a square based pyramid.
There are:
5 Faces (one on the base and 4 side faces)
8 edges. ( 4 on base and 4 on side)
5 vertices (4 on the base and one on the top)
Ya but I think its like 40 hope this helps
Answer:
t=5.5080( to 3 d.p)
Step-by-step explanation:
From the data given,
n =20
Deviation= 34/20= 1.7
Standard deviation (sd)= 1.3803(√Deviation)
Standard Error = sd/√n
= 1.3803/V20 = 0.3086
Test statistic is:
t = deviation /SE
= 1.7/0.3086 = 5.5080
ndf = 20 - 1 = 19
alpha = 0.01
One Tailed - Right Side Test
From Table, critical value of t =2.5395
Since the calculated value of t = 5.5080 is greater than critical value of t = 2.5395, the difference is significant. Reject null hypothesis.
t score = 5.5080
ndf = 19
One Tail - Right side Test
By Technology, p - value = 0.000
Since p - value is less than alpha , reject null hypothesis.
Conclusion:
From the result obtained it can be concluded that ,the data support the claim that the mean rating assigned to the wine when the cost is described as $90 is greater than the mean rating assigned to the wine when the cost is described as $10.
Answer:
Domain, range
Step-by-step explanation:
The <u>domain</u> of a function is the complete set of inputs, whereas the <u>range</u> is the set of all outputs.
Domain= Input
Range= Output
, this equation is slope intercept for, which is
so our m or slope is
then we use the equation
, so what do we multiply
by to get -1? -4 right, so that's the slope of line AB with the point (2,0)
so m= -4 and our point is (-1,6)
thats the equation of line side CD
