Carol and Peter walk to school. Carol walks 3/5 of a mile to walk to school,
Peter walks 0.65. Which student has a father walk?
For Carols situation, I divided one mile into 5 parts. 1 mile divided by 5 equals .2 miles. Since she walked 3/5 of a mile, I multiplied .2 with 3 which equals 0.6. Carol walked 0.6 Miles.
Peter walked 0.65 mile, so he walked .05 miles farther then Carol
Peter had a farther walk

Step-by-step explanation:
because 180⁰-40⁰=140⁰
Answer:
∠m = 140°
Step-by-step explanation:
∠1 and ∠m are adjacent angles, so they add up to 180°.
∠1 + ∠m = 180
40 + ∠m = 180
∠m = 180 - 40
∠m = 140°

Sweet corn of a certain variety is known to produce individual ears of com with a mean weight of 8 ounces. A farmer is testing a new fertilizer designed to produce larger ears of com, as measured by their weight. He selects a random sample of 10 ents of com and determines their weight (in ounces). The data are as follows: 8.25 7359,05 8.00 8.25 8.75 9.00 7.60 8.45 8.55
Do the data provide convincing evidence at the a=0.05 level that the fertilizer had a positive impact on the weight of the com cars?
Answer:
We can conclude that there is significant evidence that dL fertilizer has a positive impact on larger weight of coms
Step-by-step explanation:
Given the data :
8.25 7.35 9.05 8.00 8.25 8.75 9.00 7.60 8.45 8.55
Using calculator :
Mean, x = 8.325
Standard deviation, s = 0.560
Null hypothesis :
H0: μ = 8
H1 : μ > 8
The test statistic,
(x - μ) / (s/sqrt(n))
(8.325 - 8) / (0.56 / sqrt(10))
0.325 / 0.177
= 1.835
The Pvalue ; using the Tstatistic calculator ;
α = 0.05 ; df = 10 - 1 = 9
Pvalue = 0.04985
Reject H0 ; if Pvalue is < α
Hence, since 0.04985 < 0.05 ; we reject H0
. We can conclude that there is significant evidence that dL fertilizer has a positive impact on larger weight of coms

Jenny is planning an extended trip to Russia.The table below shows a list of cities which she would like to visit during her stay, along with the amount of money she anticipates needing to spend on travel, lodging, and similar expenses in each city. All costs are given in Russian rubles (RUB).
City
Cost (RUB)
Izhevsk
4,721
Novosibirsk
4,870
Nizhny Novgorod
6,920
Moscow
5,485
Chelyabinsk
5,217
Saint Petersburg
5,960
Tolyatti
5,598
Yaroslavl
4,901
Even though Jenny wants to go to each of these cities, her budget is only RUB 33,000, so she recognizes that she must change her itinerary and choose not to visit some cities. Which of the following pairs of cities will not put Jenny back under budget if she drops them?
a.
Moscow and Chelyabinsk
b.
Izhevsk and Nizhny Novgorod
c.
Novosibirsk and Saint Petersburg
d.
Yaroslavl and Tolyatti
THE ANSWER IS D. YAROSLAVI AND TOLYATTI
EXPLANATION: the total of all cities is 43,672. If we subtract 4901 for Yaroslavi and 5598 for Tolyatti we have 33,173 (43,672 - 4901 - 5598 = 33,173). This would still be over Jenny's budget
