Answer:

$5x+2y+6=0$

Step-by-step explanation:

General equations are in the form $Ax + By + C = 0$

So you can add 6 to both sides to make:

$5x+2y+6=0$

An article reported that for a sample of 58 kitchens with gas cooking appliances monitored during a one-week period, the sample

Pavel [41]

Answer:

95% Confidence Interval = (611.81 ppm, 696.51 ppm)

Step-by-step explanation:

The formula for Confidence Interval is given as:

Confidence Interval = Mean ± z × s /√n

Mean = the sample mean/average = 654.16

s = the sample standard deviation = 164.55

z = z score of 95% confidence interval = 1.96

Confidence Interval =

654.16 ± 1.96 × 164.55/√58

= 654.16 ± 42.348

Hence,

654.16 - 42.348

= 611.812

Approximately to two decimal places = 611.81 ppm

654.16 + 42.348

= 696.508

Approximately to two decimal places = 696.51 ppm

Therefore, the 95% (two-sided) confidence interval for true average CO2 level in the population of all homes from which the sample was selected is (611.81 ppm, 696.51 ppm).

Mr. Franklin asked each of his 30 students to select their favorite radio station.

Ostrovityanka [42]

Answer:

Step-by-step explanation:

We are given that

Total number of students who select their favorite radio station=30

Number of student who select their favorite radio station K= $\frac{1}{3}\times 30=10$

Number of student who select their favorite radio station L= $\frac{1}{5}\times 30=6$

We have to find that number of student who select station M.

Remaining students=30-(10+6)=30-16=14

Number of students who select their favorite radio station M=14

Hence, the number of students who select their favorite radio station M=14

Answer: 14

Which statements describe the graph of 2 8/9 ≥ x on a number line? Select three options.

andrezito [222]

Answer:

✔️The graph contains point zero

✔️There's a closed circle on 2⁸/9

✔️The arrow points to the left

Step-by-step explanation:

The inequality, 2⁸/9 ≥ x, implies that 2⁸/9 is either equal to x or more than x. In other words, the highest value of x is 2⁸/9. Possible value of x is equal to or less than 2⁸/9.

This, on a number line, we would graph the information as follows:

✔️The graph contains point zero

Rationale: point zero is less than 2⁸/9

✔️There's a closed circle on 2⁸/9

Rationale: this indicates 2⁸/9 is included in the possible value of x

✔️The arrow points to the left

Rationale: possible value of x ranges from 2⁸/9 and below.
