Answer:
Option A is correct.
The value of r = -0.7 represents the strongest negative correlation.
Step-by-step explanation:
A correlation is a value that describes a relationship between two things or variables.
Strongest Negative Correlation says that closer a negative correlation to -1, the stronger the relationship between the two variables.
From the options, we have only two negative values i.e, r= -0.7 and r= -0.22.
We have to find the strongest negative correlation r-value.
By the definition, you can see that -0.7 is very closer to -1 ,
therefore, the value of r = -0.7 represents the strongest negative correlation.
We let x and y be the measures of the sides of the rectangular garden. The perimeter subtracted with the other side should be equal to
2x + y = 92
The value of y in terms of x is equal to,
y = 92 – 2x
The area is the product of the two sides,
A = xy
Substituting,
A = x (92 – 2x) = 92x – 2x2
Solving for the derivative and equating to zero,
0 = 92 – 4x ; x = 23
Therefore, the area of the garden is,
<span> A = 23(92 – 2(23)) = 1058 yard<span>2</span></span>
Answer:
1.5 hours
Step-by-step explanation:
Calculate speed using
time = 
= 
= 1.5 hours or 1 hour 30 mins
The function is <span>b(x)= |x+4|,
which means that b(-10)=|-10+4|, since we can replace both x-es above with any number. (This is what the rule means.)
Further, |-10+4|=|-6|. We know that the absolute value gives us always positive values, so |-6|=6.
Thus, the answer is 6.
