Let x = the first numberLet y = the second number x + y = 23 eq1 y = 23- x
xy = Product eq2
Substitute eq1 into eq2. Lets get eq2 in terms of x.
Product = x(23 - x)Product = - x2 + 23x
we must find the vertex has coordinate (h, k). h = -b / 2a where:a = -1b = 23
h= -23 / -2 = 11.5
<span>x = 11.5
</span>Substitute this value of x into eq1 to find y. y = 23 - xy = 23 - 11.5y = 11.5
<span>The two numbers that will give the largest product possible are 11.5 and 11.5.</span>
Answer:
a) 54.6
b) 140
Step-by-step explanation:
7644 ÷ 140 = 54.6
so;
7644 ÷ 54.6 = 140

The value of a correlation coefficient ranges between -1 and 1.
The greater the absolute value of the Pearson product-moment correlation coefficient, the stronger the linearrelationship.
The strongest linear relationship is indicated by a correlation coefficient of -1 or 1.
The weakest linear relationship is indicated by a correlation coefficient equal to 0.
A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.
A negative correlation means that if one variable gets bigger, the other variable tends to get smaller.
therefore
d is correct
