Answer:
[tex]v=400,000 \times (2)^d[/tex]
Step-by-step explanation:
Given that,
The value of a house is 400,000 in 2015 and it doubles every decade.
Let v be the value of the house.
We need to find an equation for v in terms of d (the number of decades since 2015).
It shows that the function is exponential. So,
[tex]v=ab^d[/tex]
Where
a = Initial Value = 400000
b = rate = 2
d = number of decades
v = the current value of the home
So,
[tex]v=400,000 \times (2)^d[/tex]

Suppose the consumer group used a sample size of 50 instead of 100 for each airline. When all other things remain the same, what effect would the decrease in sample size have on the interval?
Answer:
Width of confidence interval will increase.
Step-by-step explanation:
The sample size as an effect on the width of the confidence interval being calculated as it determines the value of the error margin. In general, increasing the sample size reduces the width of the confidence that interval while decrease in its value increases the error margin and hence the confidence interval.
Confidence interval :
Xbar ± Error margin
Error margin = Tcrit * s/ sqrt(n)
n = sample size
Being the denominator, a decrease in its value will result in an increase in error margin.

Answer:
D. milimeters.
Step-by-step explanation:
Both meter and milimeter are length units. Kilogram is a mass unit. Liter is a volume unit, which is the cube of length in dimension terms. A liter equals 0.001 cubic meters or 1000000 cubic milimeters. Hence, the correct answer is D.

A pet store has 96 pets ( dogs, cats, birds) for sale. There are 3 more dog than cats. There are 9 less birds than cats. How many of each type of pet are in the shop?
Answer:
Cats = 34
Dogs = 37
birds = 25
Step-by-step explanation:
Let :
c = cats
d = dogs
b = birds
from the question, the following equation can be gotten
d = 3 + c eqn 1
b = c - 9 eqn 2
c + d + b = 96 eqn 3
substitute for b and d in equation 3
3 + c + c - 9 + c = 96
3c - 6 = 96
3c = 102
c = 34
Substitute for d in eqn 1
d = 3 + 34 = 37
Substitute for b in eqn 2
34 - 9 = 25

What is the value of a missing angle
Answer:
63°
Step-by-step explanation:
First, by looking at the angle we see that the overall angle is a right angle. This means that the total will add up to 90°.
Knowing this we can then subtract
90° - 27° = 63°
Answer:
63
Step-by-step explanation:
The measure of a right angle is always 90 so
90-27=63
