Hanna train departs at 2:15 pm , while harry departs at 3.00 pm and Howard departs at 2:35 pm (20 minutes after Hannah). Howard arrives at 3.25 pm which means he takes 50 minutes. Harry trains takes 50% longer than Howard which is 1.5 × 50 = 75 minutes( 1 hr 15 minutes . Therefore harry arrives at 4.15 pm ( 3.00 + 1 hr 15 minutes).
hence, the answer is 4.15 pm
If I'm not wrong, you must draw a graph for this
y=-2x +2
sub x=-1 ,0 and 1
and do the same for y=x^2-3x
and plot the coordinates
don't worry y=-2x+2 will be a straight line because it's x is to the power of one
and **to find the no. of solutions, refer to ur graph and count the number of point of intersections and that will be ur answer
Hope this helps :)
Answer:
q=
−4t+7u over 8r
Step-by-step explanation:
8qr+4t=7u
Step 1: Add -4t to both sides.
8qr+4t+−4t=7u+−4t
8qr=−4t+7u
Step 2: Divide both sides by 8r.
8qr
8r
=
−4t+7u
8r
q=
−4t+7u
8r
Answer:
q=
−4t+7u
8r
Answer:
equation is 15x+60<97.50
answer is 2.5 but if that doesn't make sense. To not to over, the answer would be two.
Answer:Average error will be less
Step-by-step explanation: Prediction error refers to the difference between the the actual and predicted value of an observation. Using correlation analysis or study, The level or degree of correlation or relationship between two measured variables usually determines the variation or measure of the prediction error. If there is no relationship or correlation between two measured variables, if such model is used to make prediction, the average prediction error will be very high. However, since it is stated that there exist a relationship between high school GPA and Freshman-year GPA, then making prediction based on this assertion will lessen the average prediction error.
