Since the regression equation is:  y = 30 8x. if SSE= 960,  the correlation coefficient is 0.661.

<h3>What is the regression equation about?</h3>

A regression equation is known to be a tool that is often used in statistics to examine if any relationship exists or not between a given sets of data.

Note that:

SSR=SST-SSE

So the first step is to calculate the R² which is seen as the coefficient of equation. This will be:

= 1 - SSE/SS Total

= 1 - 900/1600

= 1 - 0.5625

= 0.4375

Then, the correlation coefficient will be:

= ✓0.4375

= 0.661

Therefore, Since the regression equation is:  y = 30 8x. if sse = 960,  the correlation coefficient is 0.661.

Marissa bought four bottles of water Each bottle of water is 0.95 cents Write an equation with the same product as the total cos
zysi [14]

Answer: Total cost = Cost of each bottle × Number of bottles

Step-by-step explanation: If each bottle of water Marissa bought cost 0.95cents. This means four bottles will cost = 0.95 + 0.95 + 0.95 + 0.95 = 3.80 cents

This can be written simply as 0.95 × 4 = 3.80 cents

Therefore, a general equation for calculating the total cost of bottle water will be;

Total cost = Cost of each bottle × Number of bottles.

Find the probability that a randomly generated bit string of length 10 does not contain a 0 if bits are independent and if a 0 b
jeka94

Answer:

Step-by-step explanation:

From the given information; Let's assume that  R should represent the set of all possible outcomes generated from  a bit string of length 10 .

So; as each place is fitted with either 0 or 1

\mathbf{|R|= 2^{10}}

Similarly; the event E signifies the randomly generated bit string of length 10 does not contain a 0

Now;

if  a 0 bit and a 1 bit are equally likely

The probability that a randomly generated bit string of length 10 does not contain a 0 if bits are independent and if a 0 bit and a 1 bit are equally likely is;

\mathbf{P(E) = \dfrac{|E|}{|R|}}

so ; if bits string should not contain a 0 and all other places should be occupied by 1; Then:

\mathbf{{|E|}=1 }   ; \mathbf{|R|= 2^{10}}

\mathbf{P(E) = \dfrac{1}{2^{10}}}

6x^2 + 66x + 60 factor completely
kiruha [24]

Hi! Let me help you!

  • Remember, factoring looks like so:
  • ab+ac=a(b+c)
  • So, we need to find the greatest common factor (G.C.F.) of the polynomial.
  • In this case, 6 is the GCF, so we factor it out:
  • 6x²+66x+60
  • Divide 6, 66 and 60 by 6:
  • x²+11x+10

<u>Answer:</u>

x²+11x+10

Hope you find it helpful.
