Answer:
The slope of the red line is also 8
Step-by-step explanation:
Parallel lines never meet. So, they always have the same slope. If they had different slopes, then they would meet on the graph at some point. However, since the lines have the same slope, they will never meet since they proportionally grow at the same rate.
Answer:
-1/2 > x > -3
Step-by-step explanation:
i)
-2x+3>4
-2x> 1
x < -1/2
ii)
-2x+3<9
-2x<6
x > -3
= -1/2 > x > -3
Step-by-step explanation:
Note: Question does not indicate if probability required is for weight to exceed or below 3000 lbs. So choose appropriate answer accordingly (near the end)
Using the usual notations and formulas,
mean, mu = 3550
standard deviation, sigma = 870
Observed value, X = 3000
We calculate
Z = (X-mu)/sigma = (3000-3550)/870 = -0.6321839
Probability of weight below 3000 lbs
= P(X<3000) = P(z<Z) = P(z<-0.6321839) = 0.2636334
Answer:
Probability that a car randomly selected is less than 3000
= P(X<3000) = 0.2636 (to 4 decimals)
Probability that a car randomly selected is greater than 3000
= 1 - P(X<3000) = 1 - 0.2636 (to 4 decimals) = 0.7364 (to 4 decimals)
Answer:
<h2><em><u>
x = -1</u></em></h2>
Step-by-step explanation:
<em><u>1. Distribute</u></em>
3x + 3 = -2x + 2 - 4
<em><u>2. Simplify</u></em>
-2x + 2 - 4
2-4 = -2
-2x - 2
<em><u>3. Solve</u></em>
3x + 3 = -2x - 2
+2x +2x
<em><u>4. Cont. Solving</u></em>
5x + 3 = -2
-3 -3
5x = -5
<em><u>5. Divide by 5</u></em>
5x = -5
/5 /5
