The linear least squares regression will have a slope of:

m=(nΣxy-ΣxΣy)/(nΣx^2-ΣxΣx)

m=(5*2078-30*281)/(5*220-30*30)

m=1960/200

m=9.8

and a y-intercept of:

b=(Σy-mΣx)/n

b=(281-9.8*30)/5

b=-2.6

So the line of best fit is:

y=9.8x-2.6

Bruno will spin the arrow on the spinner 2 times. what is the probability that the arrow will stop on c at least once? 19 29 13
DIA [1.3K]

The probability that the spinner will land on c at least once is 5/9

<h3>How to determine the probability?</h3>

From the complete question, the probability that the spinner will not land on c when spun twice is:

P = 4/9

Using the complement rule, the probability that the spinner will land on c at least once is:

P' = 1 - P

This gives

P' = 1 - 4/9

Evaluate

P' = 5/9

Hence, the probability that the spinner will land on c at least once is 5/9

A prism with length of 3 units, height of 3 and one-fourth units, and width of 1 unit. What is the volume of the prism? whole-un
german

Answer:

9

2

9\dfrac{3}{4}\ \text{units}^3

Step-by-step explanation:

l = Length of prism = 3 units

h = Height of prism = 3\dfrac{1}{4}=\dfrac{13}{4}\ \text{units}

w = Width of prism = 1 unit

Volume of a prism is given by

V=lwh\\\Rightarrow V=3\times 1\times \dfrac{13}{4}\\\Rightarrow V=9.75\ \text{units}^3=9\dfrac{3}{4}\ \text{units}^3

The number of whole unit cubes that can fit inside the prism is 9

For quarter cubic units

\dfrac{9}{4}=2\dfrac{1}{4}

The number of quarter cubic units that can fit inside the prism is 2

Total volume of the prism is 9\dfrac{3}{4}\ \text{units}^3.
