For this case, what can be observed is a decrease in time by increasing the number of races in which it competes.
If you have competed in a race:
f = -0.45 * (1) +43.6
f = 43.15 min (arrival time).
If you have competed in two races:
f = -0.45 * (2) +43.6
f = 42.7 min (arrival time).
answer:
The model predicts that for each additional race a bicyclist has competed in, the finishing time decreases by about 0.45 minutes.
Let the total number of students be x;
given that the ratio of girls to boys is 5:3, then:
The equation that represents the number of girls will be:
5/8x
The equation that represents the number of boys will be :
3/8x
The equation that represents the total number of boys and girls will be:
5/8x+3/8x
B] suppose there are g number of girls. The equation that represents the number of boys in terms of number of girls will be:
(ratio of boys to girls)×(number of girls)
3/5×(g)
=(3g)/5
Answer:
8.−2x^2+6x
9.y-1
Step-by-step explanation:
8.(−2x)(x−3)
=(−2x)(x+−3)
=(−2x)(x)+(−2x)(−3)
=−2x^2+6x
9. y^2−y
y
= y^2−y
y
=y−1
Answer:
Since speed is given in terms of "hours" we must convert 9 minutes to hours:
9 minutes = 9/60 hours = 3/20 hours
.
Let x = time (hours) it takes car to pass the truck
then
60(x + 3/20) = 69x
multiplying both sides by 20:
60(20x + 3) = 1380x
1200x + 180 = 1380x
180 = 180x
1 hour = x
Step-by-step explanation:
Answer:
B. must undergo a logarithmic transformation before undergoing logistic regression.
Step-by-step explanation:
A logistic regression model allows us to establish a relationship between a binary outcome variable and a group of predictor variables. It models the logit-transformed probability as a linear relationship with the predictor variables.
