Area of deck= 2(20w)+4(w^2)+2(50w)d
456=2(20w)+4(w^2)+2(50w)
456=40w+4w^2+100w
456=4w^2+140w
114=w^2+35w
0=w^2+35w-114
find what 2 numbers multiply to get 114 and add to get 35 and factor
-3 and 38
0=(w-3)(w+38)
set each to zero
w-3=0
w=3
Answer:they will drive 500 miles each day.
Step-by-step explanation:
The Thompson family is traveling 1,500 miles to visit relatives. They plan to drive the same distance each day.
Let x represent the distance that they travel each day. If the Thompsons make the trip in 3 days, it means that the total distance that they travelled in 3 days would be
3 × x = 3x miles
Therefore , the distance that they will drive each day would be
3x = 1500
Dividing both sides of the equation by 3, it becomes
3x/3 = 1500/3
x = 500 miles
Answer:
Value of test statistics = 2.30
Step-by-step explanation:
We are given that for a sample of 35 items from a population for which the standard deviation is 20.5, the sample mean is 458.
Also, Null Hypothesis, 
: 
= 450
Alternate Hypothesis, 
: 
450
The test statistics that will be used here is One sample t-test statistics;
T.S. = 
~ 
where, 
= sample mean = 458
s = sample standard deviation = 20.5
n = sample of items = 35
So, test statistics = 
~ 
= 2.30
Therefore, the value of test statistics is 2.30 .
What you are asking is x + 30 ÷ 11 = 1
x + 30 ÷ 11 = 1
Simplify
x + 30/11 = 1
Subtract 30/11 from each side
x + 30/11 - 30/11 = 1 - 30/11
x = -19/11
