Q1: y = -3/2x +1
Q2: The graph changes vertically from -1 to 3 (4 units) at the same time it changes horizontally from -4 to 1/2 (4.5 units). The rate of change is 4/4.5 = 8/9 ≈ 0.8889. The closest answer selection is 9/10.
Q3: x=-2
Q4: The graph changes vertically by -4 at the same time it changes horizontally by +1. The slope is 4/-1 = -4. The y-intercept is +1, so the equation is
.. y = -4x +1
Q5: After the same pattern as above,
.. y = 5/2*x +5
I answered part b first before a, bec6 the answer to part b is what would aid me in answering part a
Answer:
B. The t test statistic is the appropriate test.
A. Reject the null hypothesis
Step-by-step explanation:
X1 = 6.841, sd1 = 0.155, n1 = 15
X2 = 6.701, sd2 = 0.108, n2 = 10
1. The appropriate test statistic for this question is the t test.
T = x1-x2/√sd1²/n1 + sd2²/n2
T = 6.841-6.701/√0.155²/15 + 0.108²/10
= 2.66
H0: u1 = u2
H1; u1>u2
Significance level = 0.05
Df = n1+n2-2
= 15+10-2
= 23
T critical = 1.714
2.66>1.714
So we have to reject the null hypothesis. Since we have enough evidence that supports this claim that fruit flavor bubble gum is on average, thicker than the fruit flavored gum.
Answer:
1582480848 miles
Step-by-step explanation:
The maximum distance is another vertex of the major axis
1,636,484,848 miles - 54,004,000 miles = 1582480848 miles
To find the mean....add all the values and divide by the amount of values.....since the mean is given do the opposite...multiply the mean by the amount of values and then minus each value to find x....
113113.101101 * 5 then minus 122122+107107+112112+107107 from it
Answer:
-5h - 2
Step-by-step explanation:
3h - 2(1+4h)
Let's first get rid of the ( ) by performing the multiplication:
3h - 2*1 + -2*4h = 3h - 2 - 8h
Now we can subtract 8h from 3h, and that's as simple as it gets:
3h - 2 - 8h = -5h - 2
