Answer:
Figure 1:
Area: 30m^2
Perimeter: 23.6m
Figure 2:
Area: 98.8km^2
Perimeter:56.5km
Step-by-step explanation:
Area is base x height.
To get the perimeter, add up all the sides.
Figure 1:
Area:
6x5=30m^2
Perimeter: 6+5.8+6+5.8=23.6m
Figure 2:
Area:
7.6x13 = 98.8km^2
Perimeter:7.6+15+20+13.9=56.5km
Answer:
10/25%
Step-by-step explanation:
Standard for is x × 10 ^I
where,
I = indice
10 > x < 0
you cannot write this is standard form with putting in what they stand for. However you can simplify it -
4(8m-7n) +6(3n-4m)
32m - 28n + 18n - 24m
8m - 10n
but hey I am from England do what we call standard form might be different
-1400 + 800 - 350 = - 950 meters
Answer:
3) One-sided,compare two populations
Step-by-step explanation:
A manufacturer wants to investigate the whether there is an increase in the mean gas mileage of mid-sized sedan having new type of tire compared to mean gas mileage of mid-sized sedan not having new type of tire.
So, there are two populations :
population 1 : mid-sized sedan having new type of tire.
population 2 : mid-sized sedan not having new type of tire.
So, two populations are being compared.
Also, A manufacturer is investigating whether there is an increase in mean gas mileage.The alternative hypothesis will be right tailed and so, this corresponds to one sided test.
