Answer:
The train engine is <u>15 centimeters</u> long.
Step-by-step explanation:
The train car length doesn't matter. All you need to do is subtract 32 cm from the total length, 47 cm.
47-32=15 cm
The train engine is 15cm long.
Answer:
The 93% confidence interval for the equatorial radius of Jupiter is between 71484 km and 71500 km.
Step-by-step explanation:
Sample size of 30 or larger, so we can use the normal distribution to find the confidence interval.
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 71492 - 8 = 71484 km.
The upper end of the interval is the sample mean added to M. So it is 71492 + 8 = 71500 km.
The 93% confidence interval for the equatorial radius of Jupiter is between 71484 km and 71500 km.
The white Christmas tree is 7.55m
Green Christmas tree is twice as tall as white Christmas tree: 7.55 * 2 = 15.1m
High golden Christmas tree: 15.1m - 0.454m = 14.646m
The total height of 3 Christmas trees is: 7.55m + 15.1m + 14.646m = 37.296m
Choose: A 37.296m
<h3>
The probability of not choosing 2 peaches is .</h3>
Step-by-step explanation:
Here, the total number of bins = 10
Total orange bins = 2
Total apples bins = 3
Total peaches bins = 4
Total melon bins = 1
Let E : Event of picking two peaches
So, P(Picking 1 peach ) =
and P (Picking 2nd peach ) =
So, the probability of not picking 2 peaches = 1 - P(picking 2 peaches)
Hence, the probability of not choosing 2 peaches is .
If there are 4 friends and 1 flashlight and only two of them can pass at a time then
that will mean that has to pass 2 times per person and the last time only one
for 32 will be 31*2 + 1 = 63
in a general matter will be
T = (X-1)*2 + 1
T = 2X - 1
so for 3 friends will be (this does not take into consideration the flashlight guy)
T = 3*2 - 1 = 5 times
