Answer:
x≤61/12
Step-by-step explanation:
distribute the -3
8-12x+3≥-49
add like terms
12-12x≥-49
subtract 12 from both sides
-12x≥-61
divide by -12, when you divide by a neg the lessthan/greaterthan sign flips
x≤61/12

A study done by researchers at a university concluded that 70% of all student-athletes in this country have been subjected to some form of hazing. The study is based on responses from 1800 athletes. What are the margin of error and 95% confidence interval for the study?
Answer:
Step-by-step explanation:
Given that:
The sample proportion [tex]\hat p = 0.70[/tex]
The sample size n = 1800
At 95% confidence interval level:
The level of significance = 1 - 0.95 = 0.05
Critical value: [tex]Z_{0.05/2} = Z_{0.025} = 1.96[/tex]
Thus, the Margin of Error E = [tex]Z_{\alpha/2} \times \sqrt{\dfrac{\hat p ( 1- \hat p)}{n}}[/tex]
[tex]= 1.96 \times \sqrt{\dfrac{ 0.70 ( 1-0.70)}{1800}}[/tex]
[tex]= 1.96 \times \sqrt{\dfrac{ 0.70 ( 0.30)}{1800}}[/tex]
[tex]= 1.96 \times \sqrt{\dfrac{0.21}{1800}}[/tex]
[tex]= 1.96 \times \sqrt{1.16666667\times 10^{-4}}[/tex]
the Margin of Error E = 0.021
At 95% C.I for the population proportion will be:
[tex]= \hat p \pm Z_{\alpha/2} \sqrt{\dfrac{\hat p(1- \hat p)}{n}}[/tex]
= 0.70 ± 0.021
= (0.70 - 0.021, 0.70 + 0.021)
= 0.679, 0.721)

Answer:
Step-by-step explanation:The amount coach smith will spend is given by
11(3(48) + 2(5) + 17 + 2(89)) = 11(144 + 10 + 17 + 178) = 11(349) = $3,839
The basketball team scored 89 points in just two- and three-point basket. The number of two-point baskets was 27 more than the number of three-point baskets. How man two-point and three-pointers did the team make?
Answer:
A=85
B=58
Step-by-step explanation:
NO. OF 2 point basket⇒ A
NO. OF 3 point basket⇒B
A+B=89⇒ EQN 1
A=27+B
A-B=27⇒EQN 2
EQN 1 - EQN 2
2B=116
B=58
THEREFORE
A=27+58
A=85

Find the 66th term in the following arithmetic sequence: -92,-85,-78,-71,.......
9514 1404 393
Answer:
363
Step-by-step explanation:
The n-th term of an arithmetic sequence is given by ...
an = a1 +d(n -1)
Here, the first term (a1) is -92, and the common difference is (-85 -(-92)) = 7. The 66th term is ...
a66 = -92 +7(66 -1) = -92 +455
a66 = 363

b) B(-6, -2), C(-3, 3) and D(2,0), E(5,5)
c) N(-6,2), P(--3, -4) and Q(1, -3), R(3, 4)

Answer:
a. ST and UV are perpendicular lines.
b. BC and DE are parallel.
c. NP and QR are neither parallel nor perpendicular.
d. GH and JK are parallel.
Step-by-step explanation:
Slopes are used to calculate steepness of a line. Slopes are also used to check if two lines are parallel, perpendicular or neither.
When two lines are parallel, their slopes are equal.
When two lines are perpendicular, product of slopes of both lines is -1
Slope is given by the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
a) S(-4, -1), T(-1,5) and U(1,1), V(5, -1)
[tex]Slope\ of\ ST = \frac{5+1}{-1+4} = \frac{6}{3} = 2\\Slope\ of\ UV = \frac{-1-1}{5-1} = \frac{-2}{4} = -\frac{1}{2}[/tex]
Now,
[tex](Slope\ of\ ST)(Slope\ of\ UV) \\= 2 * -\frac{1}{2}\\=-1[/tex]
ST and UV are perpendicular lines.
b) B(-6, -2), C(-3, 3) and D(2,0), E(5,5)
[tex]Slope\ of\ BC = \frac{3+2}{-3+6} = \frac{5}{3}\\Slope\ of\ DE = \frac{5-0}{5-2} = \frac{5}{3}[/tex]
As the slopes of two lines is equal, BC and DE are parallel.
c) N(-6,2), P(--3, -4) and Q(1, -3), R(3, 4)
[tex]Slope\ of\ NP = \frac{-4-2}{-3+6} = \frac{-6}{3} = -2\\Slope of\ QR = \frac{4+3}{3-2} = \frac{7}{2}[/tex]
NP and QR are neither parallel nor perpendicular.
d) G(-2,5), H(4,1) and J(1, –4), K(7,0)
[tex]Slope\ of\ GH = \frac{1-5}{4+2} = \frac{-4}{6} = -\frac{2}{3}\\Slope\ of\ JK = \frac{0-4}{7-1}= \frac{-4}{6} = -\frac{2}{3}[/tex]
GH and JK are parallel.
Hence,
a. ST and UV are perpendicular lines.
b. BC and DE are parallel.
c. NP and QR are neither parallel nor perpendicular.
d. GH and JK are parallel.

jarak kota a ke kota b adalah 130 km Amir berangkat dari a pukul 8.15 menuju b dengan kecepatan rata-rata 50 km per jam Amir tiba di kota b pada pukul
Answer:
10:51
Step-by-step explanation:
Given that :
Distance from A to B = 130km
Departure time = 8 : 15
Average speed = 50 km/hr
Recall :
Speed = distance / time
Time = distance / speed
Time = (130 km) ÷ (50km/hr)
Time = 130 / 50
Time = 2.6 hours = 2 hours + (0.6 * 60) = 2 hours 36 minutes
Arrival time = (8:15) + (2 hours 36 minutes) = 10:51

2.) True or False?
When working with a function, substituting a certain value of x into the formula gives only one value of y for that value of x.
Answer:
TRUE
Step-by-step explanation:
In a function, every domain value (x-value) must have exactly one corresponding range value (y-value). This means that in a function, an x-value or input value cannot have two different y-value or output value. Or else, it ceases to be a function.
So, when you substitute a certain value of x into the equation of a function, you can only have one exact value of y for that value of x.
