hello i see that no one has answered your question yet well im here to help:)
(1,-19),(-2,-7)
so here one way you can find the slope
i usually always use this to help me to keep it in order
------------------
(X1,Y1)(X2,Y2)
X2-X1
Y2-Y1
use this and your garanteed to get the right answer everytime
------------------
X = -2 – 1 = -3
Y = -7 – -19 = 12
once you do that you divide if possible
12/-3
which gives you -4
so your answer is -4
its really not hard you just got to get use to it
hope it help you:)
Answer:
Yes, hypertension drugs lowers blood pressure.
Step-by-step explanation:
Claim: The hypertension medicine lowered blood pressure.
The null and alternative hypothesis is
H0:\mu_{d}\geq 0
H1:\mu_{d}< 0
Level of significance = 0.05
Sample size = n = 13
Sample mean of difference = \bar{d} = 10.1
Sample standard deviation of difference = s_{d} = 11.2
Test statistic is
t=\frac{\bar{d}}{s_{d}/\sqrt{n}}
t = ((10.1) / (11.2 /squre root of 13)) = 3.251
Degrees of freedom = n - 1 = 13 - 1 = 12
Critical value =2.179( Using t table)
Test statistic | t | > critical value we reject null hypothesis.
In Conclusion: The hypertension medicine lowered blood pressure
Answer:
81,900 units of Product A
Step-by-step explanation:
Product C: 39,000
Product B: [39,000 - (39000 x .40)] = 39,000 - 15,600 → 23,400
Product A: 23,400 x 3.5 = 81,900
Answer:
$15
Step-by-step explanation:
You know that 3 pillows = $45
So you have to divide 45 by 3 to get the unit rate.
45÷3=15
Opposite sides are parallel.
Opposite sides are congruent.
Opposite angles are congruent.
Consecutive angles are supplementary.
The diagonals bisect each other.
