The residual value comes out to be 2.94 cm and height is 157.06 cm
<u>Explanation:</u>
The regression equation is calculated at the first step.
height = 105.08 plus 2.599 multiply foot length
At foot length = 20cm, height = 105.08 plus 2.599 multiply 20
= 157.06 cm
Residual = Actual minus predicted value = 160 minus 157.06
=2.94 cm
B) The residual standard deviation generally gives a sense of the goodness of fit of goodness of regression equation on our data. The magnitude tells us that how much will be predicted values from model will vary from actual values. the linear model is justified.
Answer:
(1)
Step-by-step explanation:
x - 2 = - 5 Add 1 to each side
x = - 5 + 2
x = - 3
Now go to the next part
(x - 2)^2
(-3 - 2)^2
(- 5)^2
Now it's a good idea at this point to separate the squared. It means that two numbers that are the same are to be multiplied together.
(-5)(-5) Two minuses are going to give you a plus.
5 * 5 = 25
(-5) * (-5) also give you 25
The answer is (1)
I would say between 2 and 4 because you are using ration recipe 4: 8 :4 10:5
12:6
recipe 2: 6:3 10:5 14:7 all you doing is trying to find whats ratio is greater.. hope it helps
Answer:
The cost of the rides are 3 tickets
And 1 ticket per game
The ride and game cost 3 tickets and 1 ticket for each respectively.
Step-by-step explanation:
Step 1 of 5
Let <em>a</em> be the number of tickets per ride costs. And <em>b</em> be the number of tickets per game costs.Thus from the given, we get the equations. For Scott, <em>5a+4b=19</em> For Isaac, <em>7a+2b=23</em>
Step 2 of 5
Multiplying the equation 2 by 2, we get <em>5a+4b=19→1</em> <em>14a+4b=46→2</em>
<em>Step 3 of 5</em>
<em>By subtracting both the equations, we get </em>
<em>(−)5a+4b=1914a+4b=46 </em>
<em>_____________ </em>
<em>−9a =−27 </em>
<em> a=−27−9⇒a=3</em>
Step 4 of 5
<em>Substituting the above value in the equation 1, we get5(3)+4b=1915+4b=194b=19−154b=4b=44⇒b=1</em>
<em>Step 5 of 5 </em>
<em>The solution is (3,1).The cost of the rides is 3 tickets per ride.The cost of the games is 1 ticket per game.</em>
