Grade 6 students sold 318 tickets for a school pay. The number of adult tickets was six

9966 [12]

Total: 318
Student tickets: x
Adult tickets: 3x+6

x+(3x+6)=318 -> 4x+6=318 -> 4x=312 -> x=78

3(78)+6 = 234+6 = 240

240 adult tickets were sold

Find the value of y, given value of x

baherus [9]

Answer:

a. y = 2+4.3x when x = -6

substituting value of x, we get

y=2+4.3*-6=2-25.8=23.8

b. y = (x-3)² when x = 9

substituting value of x, we get

y=(9-3)²=6²=36

c. y=x-2 when x = 3.5

substituting value of x, we get

y=3.5-2=1.2

d. y=5x-4 when x = - 2

substituting value of x, we get

y=5*-2-4=-10-4=-14

US consumers are increasingly using debit cards as a substitute for cash and checks. From a sample of 100 consumers, the average

scoray [572]

Answer:

A. Margin of error = 128.79

B. The 99% confidence interval for the population mean is (7661.21, 7918.79).

Step-by-step explanation:

We have to calculate a 99% confidence interval for the mean.

The population standard deviation is know and is σ=500.

The sample mean is M=7790.

The sample size is N=100.

As σ is known, the standard error of the mean (σM) is calculated as:

$\sigma_M=\dfrac{\sigma}{\sqrt{N}}=\dfrac{500}{\sqrt{100}}=\dfrac{500}{10}=50$

The z-value for a 99% confidence interval is z=2.576.

The margin of error (MOE) can be calculated as:

$MOE=z\cdot \sigma_M=2.576 \cdot 50=128.79$

Then, the lower and upper bounds of the confidence interval are:

$LL=M-t \cdot s_M = 7790-128.79=7661.21\\\\UL=M+t \cdot s_M = 7790+128.79=7918.79$

The 99% confidence interval for the population mean is (7661.21, 7918.79).

What is the approximate circumference of a circle with a diameter of 300 feet? Use π≈3.14.

lukranit [14]

The approximate circumference of the circle with the diameter of 300 feet, would be C. 942 feet. Since C = Pi • diameter = 3.14 • 300 which would be about 942 feet.

What is the equation in point-slope form for the line parallel to y=-8x - 5 that contains j(-2, 9)

Julli [10]

Answer:

y - 9 = -8(x + 2)

Step-by-step explanation:

What is the equation in point-slope form for the line parallel to y=-8x - 5 that contains j(-2, 9)

Step 1

y intercept =

y = mx + b

y=-8x - 5

m = -8, b = -5

Point slope form

y - y1 =m( x - x1)

We are given coordinates:

j(-2, 9) = (x1, y1) where ,

x1 = -2

y1 = 9

Hence, our point slope form equation is:

y - 9 = -8(x -(-2))

y - 9 = -8(x + 2)
