The owner of a large fast food chain is considering whether to re-open the dining rooms of his restaurants now that it is legal in the state of Georgia. He is interested to know what percentage of his employees support the re-opening, so he decides to conduct a survey. (a) Which of the following plans would be more likely to produce a sample statistic very close to the true percentage who support re-opening? A simple random sample of 34 employees A simple random sample of 340 employees Both plans are equally likely to get this result, since they are both random samples. (b) He thinks it would be easier to sample employees by randomly selecting franchise locations (individual restaurants) and asking managers to administer surveys to all the workers at the selected restaurants, what kind of sampling method should he use? a) Cluster sample b) Systematic sample c) Convenience sample d) Stratified sample
Answer:
a) A simple random sample of 340 employees
b) a) Cluster sample
Step-by-step explanation:
a) Remember, the sample size of most research work is a factor to consider in other to determine if the data collected represents the true percentage of the entire population.
Hence, a small random sample of 34 employees will not give more precise information than a larger sample of 340 employees because the larger sample contains more representation of the population.
b) A cluster sample is best used in this case because it involves dividing the population into several clusters or groups, then the researcher randomly selects a particular cluster or group in other collect research data for analysis.
Whereas in this case, the randomly selected clusters are the different (individual restaurant) franchise locations.
Skyler has twice as many apples in her grocery bag as her
friends Macy and Janelle combined. Macy has 15 apples
in her bag. Skyler has 50 apples in her bag. How many
apples does Janelle have in her grocery bag?
The equation 2(x+15) = 50 models this situation. Which choice shows the
sequence of operations needed to solve this problem, using both arithmetic
and algebra?
WILL GIVE BRAINLIEST
Answer:
Skyler has 130 apples in her bag
Step-by-step explanation:
well first you have to add 15 and 50 and get 65 then you have to multiply 65 by two and get 130
please give brainliest
the correct answer is to
divide by 2:
2(x+15)/2 =50/2
(x+15)=25
subtract 15:
x+15-15=25-15
x=10

Answer:
m∠SRT = 33° ∵ m∠QRT = m∠SRT
Step-by-step explanation:
Given the diagram,
RT bisects ∠SRQ, and m∠QRT = 33°
RT bisecting ∠SRQ means RT will bisect ∠SRQ into two equal angles, which are:
m∠QRT = m∠SRT
as
m∠QRT = 33°
so
m∠SRT = 33° ∵ m∠QRT = m∠SRT

2x + y + z = 9
-x-y +z = 1
3x - y +z=9
Answer:
603 hope this helps
Answer:
x = 2
y = 1
z = 4
Step-by-step explanation:
Step 1:
2x + y + z = 9
3x - y = z = 9
5x + 2z = 18 <-- add x and y
Step 2:
-x -y + z = 1
2x + y + z = 9
x + 2z = 10
Step 3:
-(x + 2z = 10) = -x - 2z = -10
5x + 2z = 18
-x - 2z = -10
4x = 8
x = 2
Step 4: solve for z
-x - 2z = -10 <-- Plug x
-(2) - 2z = -10
-2z = -8
z = 4
Step 5: solve for y
2x + y + z = 9
2(2) + y + 4 = 9
8 + y = 9
y = 1

Ruby has $2.10 in nickels and dimes.
She has three as many dimes as nickels. How many nickels and dimes does she have?
Answer:
$
Step-by-step explanation:
Unit conversion is the conversion of one unit to another unit with its standard conversion.
20 nickels = $1
10 dimes = $1
1 nickel = 5 cents
1 dimes = 10 cents
The number of nickels is 5.
The number of dimes is 15.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Example:
1 minute = 60 seconds
1 km = 1000 m
We have,
20 nickels = $1
10 dimes = $1
1 nickel = 5 cents
1 dimes = 10 cents
Now,
Let,
Dimes = 3x
Nickels = x
Now,
The total number of cents.
10(3x) + 5x = 180
30x + 5x = 180
35x = 180
x = 5.14
x = 5
Now,
3x = 3 x 5 = 15
Thus,
The number of nickels is 5.
The number of dimes is 15.

Write the equation of the line with a slope of -1.6 and a y-intercept of 4 in slope-
intercept form.
Answer:
y = -1.6x + 4
Step-by-step explanation:
y = mx + b
y = (-1.6)x + (4)
y = -1.6x + 4
The equation of line with a slope of -1.6 and a y-intercept of 4 in slope- intercept form is,
⇒ y = - 1.6x + 4
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
We have to given that;
Slope of the line (m) = - 1.6
And, The y - intercept = 4
We know that;
The slope intercept form of an equation of line is,
⇒ y = mx + b
Where, 'm' is slope of the line and 'b' is y - intercept of the line.
Hence, The equation of line with a slope of -1.6 and a y-intercept of 4 in slope- intercept form is,
⇒ y = mx + b
⇒ y = - 1.6x + 4
