Answer:
m = 0
Step-by-step explanation:
The denominator of the rational expression cannot be zero as this would make the rational expression undefined. Equating the denominator to zero and solving gives the value that m cannot be.
4m² = 0 ⇒ m² = 0 ⇒ m = 0 ← excluded value
Answer:
Yes, the test was conducted with a risk of a type I error.
Step-by-step explanation:
If we reject the null hypothesis, does this mean that we have proved it to be false beyond all doubt? Explain your answer.
Yes, for a null hypothesis to be rejected, it has being proven beyond all doubt that the null hypothesis will not work. the normal distribution has being used for the probability calculation.
if the null hypothesis is rejected and the alternative hypothesis is accepted, a type I error as occur.
In general terms:
‘a hypothesis has been rejected when it should have been accepted’. When this occurs, it is called a type I error.
It increased by 15 65-15=50
answer
1385
explanation
to find the total, subtract the amount they earned by the amount they spend
total = earned - spent
earned
each week, Mr. Smith earns 1900 and and his earns 1150, so add these values together to find the total amount they earn
earned = 1900 + 1150
earned = 3050
spent
they spend money on food, gas, mortgage, and savings, so add these values together to find the total amount they spend
spent = food + gas + mortgage + savings
spent = 300 + 90 + 875 + 400
spent = 1665
total
now that we know how much they earn and spend, we can find the total
total = earned - spent
total = 3050 - 1665
total = 1385
every week they have 1385 left over
