What is the minimum duration for which an apartment remained empty for the company to update the kitchen appliances? Round to the nearest whole number.
Answer:
133 days
Step-by-step explanation:
We are given;
Population mean; μ = 85 days Population standard deviation; σ = 29 days
significance level; α = 5% = 0.05
Critical value of z at significance level of 0.05 = 1.645
Now, formula for z-score is;
z = (x - μ)/σ
Where x is the minimum duration for which an apartment remained empty for the company to update the kitchen appliances.
1.645 = (x - 85)/29
(1.645 × 29) = x - 85
47.705 = x - 85
x = 85 + 47.705
x = 132.705
x ≈ 133 days
Answer: 37 days

Find the surface area of the square pyramid (above) using its net (below). *4 by 3* CAN SOMEONE PLZ HELP ME ASAP!!!???
Answer:
24 units squared
Step-by-step explanation:
you have to first find the area of the base, which is 4 * 4 which is 16. then, to find the area of the triangles, you multiply the base by height, 4 * 3 = 12, and since we have 4 triangles, and one triangle would be (1/2) * base * height, you can multiply this result by 2, which would equal 24
Laurel ran 3 miles in 24 minutes.At that rate,how long will it take her to run 7 miles?
Answer:
it took her 60 mins which is a hour
Step-by-step explanation:
you would simply add 24 plus 24 and get 48 then u would take 24 and divide that by 2 and get 12 and then u would add 48 and 12 and get the final answer of 60
Answer:
it would take laurel 56 minutes to run 7 miles.
Step-by-step explanation:
She has to run 7 miles, so if she can run 3 in 24 minutes, you can double that time to 48 minutes to run 6 miles, on top of adding another 8 minutes due to 1/3 of 24 (the third being equal to 1 mile since 24 is 3 miles) being 8, leaving you with 56 minutes for her 7 mile run.

What is the minimum value of F(x)= 10x^{2} -6x-3
3/10 or -39/10
Answer: 3/10
Step-by-step explanation:
Take the derivative of [tex]10x^2-6x-3[/tex] to get [tex]20x-6[/tex]. Set that equal to 0 to find the critical points of the function. The critical points is when the slope is either 0 or undefined.
Now do:
[tex]20x-6=0\\20x=6\\x=\frac{6}{20} = \frac{3}{10}[/tex]
There are quite a few more steps to actually find the minimum, but for this example you can automatically assume its a minimum because it is the only critical point of the function. Ill show you these extra steps tho.
Plug in two numbers into the derivative. One that is less than 3/10 and one that is greater than 3/10. The numbers 0 and 1 are fine. When x = 0, the function is -6. When x = 1, the function is +14. A switch from negative to positive indicates a minimum value

Isaac bought 18 boxes of cereal. This is 30% of the total boxes at the store. How many total boxes of cereal were at the store?
Answer:
60
Step-by-step explanation:
30% of total boxes at the store is equal to 18
so
[tex](30 \div 100 ) \times x = 18 \\ x = 18 \times( 100 \div 30) = \\ 18 \times (10 \div 3) = \\ 6 \times 10 = 60[/tex]
The 18 boxes of cereal Isaac purchased. This represents 30% of all the boxes in the store then total boxes of cereal at the store exists 60.
What is meant by percentage?Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100. Nothing is zero percent; everything is 100 percent; half of something is 50 percent; and nothing is zero percent. To exstimate a percentage, you divide the portion of the whole by the whole itself and multiply by 100.
%, which is a relative figure used to denote hundredths of any quantity. Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.
The total no of boxes = y × 100/x
Given x = 30%
y = 18 boxes
Total boxes at the store = 18 × 100/30 = 60
Therefore, the total boxes of cereal at the store exists 60.

the two angles are supplementary if a=19x+3 and b= 21x +17 solve for x and find the measure of each angle
Answer:
x = 4
a = 79
b = 101
Step-by-step explanation:
Supplementary means equal to 180° after all angles are added together.
a=19x+3
b= 21x +17
(19x+3) + (21x +17) = 180
19x + 3 + 21x + 17 = 180
40x + 20 = 180
40x = 160
x = 4
a = 19(4)+3 = 79
b = 21(4) +17 = 101

Which function has a greater degree?
Answer:
I think it's either B or C because A and D don't make sense in my opinion.
Step-by-step explanation:
The degree of the p (x) is greater because r (x) is quadratic.
What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
Given that;
The function p (x) is,
⇒ p (x) = 4x³ - 2x² + 15
And, The function of r (x) is find by table.
Here, By the given table;
The degree of r (x) is 2, because it is quadratic.
And, The degree of p (x) is 3.
Thus, We can conclude that;
The degree of the p (x) is greater because r (x) is quadratic.

Which equation shows a proportional relationship? *
y= -2x +5
y= 3+ 5x
y= -3x
Answer:
y= -3x
Step-by-step explanation:
The graph of a line with a proportional relationship would have the line go through the origin.
Since the 'y=-3x' equation only shows the slope of the line, it goes through (0,0), or the origin, as it's y-intercept.
y= -3x should be the correct answer.

What is a line segment?A line segment is simply defined as the portion of a line connecting two points that are known to be the endpoints.
From the information given, we have that;
Line RS has three segments which are line RS, Line ST and line RT, also S is the midpoint between points R and T
Given that;
Line RS = 2xLine ST = 5x + 4Line RT = 32Then,
RS + ST = RT
Substitute the values
2x + 5x + 4 = 32
collect like terms
7x + 4 = 32
7x = 32 - 4
7x = 28
Make 'x' the subject
x = 28/ 7
x = 4
Thus, the value of x is 4
