Answer:
-35/8 = t
Step-by-step explanation:
-7/4 = 2/5t
Multiply each side by 5/2 to isolate t
-7/4 * 5/2 = 2/5t * 5/2
-35/8 = t
Answer:
C. Approximately normal
Step-by-step explanation:
We know that when we have, np≥10, and n(1−p)≥10, and both of these are true, where n is the sample size, and p is the sample of proportions, the sampling proportions of sample distributions, will be normal in shape.
Expected successes : np=125(0.88)=110≥10
Expected failures : n(1−p)=125(1−0.88)=15≥10
Answer:
$4,160,000
Step-by-step explanation:
First, find the length of the new road in km using Pythagorean Theorem.
According to Pythagorean Theorem:
c² = a² + b²,
Where, c is the longest leg, which is the hypotenuse, a and b are the 2 other legs of the ∆.
Since we are calculating the lenght in km, convert each lenght of the two legs of the ∆ into km.
1 km = 1,000 m
10,000 m = 10 km
24,000 m = 24 km
c² = 24² + 10²
c² = 576 + 100
c² = 676
c = √676
c = 26 km
Lenght of the new road = 26 km
If cost of construction is $160,000 per kilometer, therefore, cost of constructing 26 km road = 160,000*26 = $4,160,000
Answer: 2nd one
because they match the relationship with y and x!!
Glad to help :)
