Cole is finding the quotient of 78 + 4. He creates this model to help him solve the division problem.
Which statements are true about Cole's work? Check
all that apply.
Cole's model correctly shows that the quotient of 78
+4 is 12 with a remainder of 30.
Cole has not finished modeling this problem.
Cole needs to add another ten block to his model to
show 78
Cole should have divided the 3 extra tens blocks into
30 ones blocks
A complete modelywould show the quotient of 78 + 4
is 19 with a remainder of 2.

What is the surface area of the sphere?

Acell phone company offers two plans to its subscribers. at the time new subscribers sign up, they are asked to provide some demographic information. the mean yearly income for a sample of 40 subscribers to plan a is $45,000 with a standard deviation of $9,200. for a sample of 25 subscribers to plan b, the mean income is $64,300 with a standard deviation of $7,100. at the 0.025 significance level, is it reasonable to conclude the mean income of those selecting plan b is larger? assume unequal population standard deviations. hint: for the calculations, assume the plan a as the first sample. what is the decision rule? (negative amount should be indicated by a minus sign. round your answer to 3 decimal places.) compute the value of the test statistic. (negative amount should be indicated by a minus sign. round your answer to 2 decimal places.) what is your decision regarding h0 ? reject h0 fail to reject h0 compute the p-value. less than 0.01 between 0.01 and 0.025 between 0.025 and 0.05 between 0.05 and 0.10 greater than 0.10
