Answer:
False
Step-by-step explanation:
70 is larger than 58 to be a factor and that makes the point that this is false.
The first thing you should do when solving equations is to check for like terms. If you do find any like terms, combine them.
6d - 3d + 2d - 6 = 4d
On the left-hand side, we can combine the d terms.
6d - 3d + 2d - 6 = 4d
5d - 6 = 4d
The next is to get the variable we're trying to solve for all alone. To do that, we'll have to add / subtract / multiply / divide on both sides of the equation.
5d - 6 = 4d
-6 = -d
Here I subtract 5d from each side of the equation which resulted the d variable almost being all alone. It's being multiplied by a -1, which is the reason why it has a negative sign. To get rid of the -1, divide both sides by -1.
-6 = -d
-6 / -1 = -d / -1
6 = d
So, d is equal to 6.
Answer:
It is not enough evidence to reject null hypothesis. It is not enough evidence to say that mean score is not equal to 35.
Step-by-step explanation:
1. Null and alternative hypothesis
2. Significance level
Freedom degrees is given by:
For a sgnificance level of 0,01 and 22 freedom degrees, t-student distribution value is:
3. Test statistic
In this case, we have an one left tailed analysis, it means that null hypothesis is rejected if
Conclusion:
It is not enough evidence to reject null hypothesis. It is not enough evidence to say that mean score is not equal to 35.
Answer:
12:30 pm
Step-by-step explanation:
8:30 am pond is empty
10:30 am pound is 1,400 gallons full
time? pound is 2,800 gallons full
from 8:30 to 10:30 are 2 hours so the rate of filling up is
1,400 gallons in 2 hours
to have a whole pond filled we need another 2 hours because
in another 2 hours will have another 1,400 gallons so a pound full. 8:30 am + 2hours = 12:30 pm
8:30 am pond is empty
10:30 am pound is 1,400 gallons full
12:30 pm pound is 2,800 gallons full.
