Answer:
(-4,3）
Step-by-step explanation:
The intervals are denoted as:
Closed intervals = [a, b]
This interval includes a and b.
Open intervals = (a, b)
This interval does not include a and b.
The interval that denotes the values between -4 and 3 on the given number line is [-4, 3].
What are intervals?The intervals are numbers or values between two given point
The intervals are denoted as:
Closed intervals = [a, b]
This interval includes a and b.
Open intervals = (a, b)
This interval does not include a and b.
We have,
A number line.
The set of values that is in the blue line is from -4 to 3.
This means that the blue line includes values from -4 to 3.
There are infinite numbers between -4 to 3.
The blue line denoted that the values -4 and 3 are also included.
The interval that denotes the values between -4 and 3 is:
= [-4, 3]
Thus,
The interval that denotes the values between -4 and 3 on the given number line is [-4, 3].

On Sunday, a local hamburger shop sold a combined total of 320 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the number of hamburgers sold. How many hamburgers were sold on Sunday?
Answer:
80
Step-by-step explanation:
1) if the number of hamburgers is 'h', number of cheesburgers is 'c', then
2) the condition 'The number of cheeseburgers sold was three times the number of hamburgers' can be written as c=3h. Also
3) the condition 'combined total of 320' can be written as h+c=320, then
4) it is possible to make up the system of equations:
[tex]\left \{ {{c=3h} \atop {c+h=320}} \right. \ = > \ \left \{ {{c=240} \atop {h=80}} \right.[/tex]
5) finally, number of hamburgers is 80.

Last year, Kevin had 20,000 to invest. He invested some of it in an account that paid 6% simple interest per year, and he invested the rest in an account that paid 10% simple interest per year. After one year, he received a total of $1480 in interest. How much did he invest in each account?
$13,000 was invested at 6% whereas $7,000 was invested at 10% using simple interest approach
What is simple interest?
Simple interest is determined as the amount invested multiplied by the interest rate and the number of years that investment lasts.
I=PRT
I=interest
P=principal
R=rate of return
T=time
Let X be the amount invested at 6%
I at 6%=6%*X*1
I=0.06X
The amount invested at 10% is 20,000-X
total interest=0.06X+0.10*(20000-X)
total interest=1,480
1480=0.06X+0.10*(20000-X)
1480=0.06X+2000-0.10X
1480-2000=0.06X-0.10X
-520=-0.04X
X=-520/-0.04
X=13,000
13,000 was invested at 6%
amount invested at 10%=20,000-X
amount invested at 10%=20,000-13,000

The diameter of a pipe is normally distributed, with a mean of 0.8 inch and a variance of 0.0004. What is the probability that the diameter of a randomly selected pipe will exceed 0.84 inch? (You may need to use the standard normal distribution table. Round your answer to three decimal places.) . Hint: take the square root of the variance to find the standard deviation.
The probability that the diameter of a randomly selected pipe will exceed 0.84 inch is 0.977
What is probability?Probabilities are used to determine the chances, likelihood, possibilities of an event or collection of events
How to determine the probability?The given parameters are:
Mean = 0.8
Variance = 0.0004
Calculate Standard deviation using
σ = √σ²
This gives
σ = √0.0004
Evaluate
σ = 0.2
Calculate the z-score at x = 0.84 using
z = (x - [tex]\bar x[/tex])/σ = √σ²
This gives
z = (0.84 - 0.8)/0.02
Evaluate
z = 2
The probability is then represented as:
P(x > 0.84) = P(z > 2)
Next, we look up the value of the z table of probabilities
From the z table of probabilities, we have:
P(x > 0.84) = 0.977
Hence, the probability that the diameter of a randomly selected pipe will exceed 0.84 inch is 0.977

Write an equation in standard form of the line passing through the points (3, 5) and (8, 15)
hi,
a point is given ( x; y)
standar line equation is : y = ax+b
So with (3;5) and (8;15) we have :
3a+b = 5
8a+b = 15
so :
8a+b - ( 3a +b) = 15 -5
8a +b -3a -b = 10
8a-3a = 10
5a = 10
a = 10/5
a = 2
if a = 2 so 3*2 +b = 5
6+b = 5
b = 5-6
b = -1
so let check :
8*2 + (-1) = 16 -1 = 15
and 3*2 -1 = 6-1 = 5

The intensity (1) of a light source is inversely proportional to the square of the distance (d) from the source. If the intensity is 16 lumens at a distance of 16 feet, what is the intensity at a distance of 14 feet? Round to the nearest hundredth.
The intensity at a distance of 14 feet is 18.29 ft
How to find the intensity of light?The intensity (I) of a light source is inversely proportional to the square of the distance (d) from the source.
Light intensity refers to the strength or amount of light produced by a specific lamp source
The light intensity is measured in terms of lumens per square foot or lumens per square meter.
Therefore,
I ∝ 1 / d²
Hence,
I = k / d²
where
I = intensity of lightd = distance form the sourceTherefore,
k = Id²
k = 16 × 16
k = 256
Hence,
I = 256 / 14
I = 18.2857142857
I = 18.29 ft

Using the z-distribution, a sample of 609 nickels has to be weighed.
What is a z-distribution confidence interval?The confidence interval is:
[tex]\overline{x} \pm z\frac{\sigma}{\sqrt{n}}[/tex]
The margin of error is:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

Step-by-step explanation:
First, lets use the functions to find the answer to f(-8) and g(4)
f(-8) is the same as asking for the value of y when x is -8
Therefore, f(-8) = -5 (according to the graph)
Using the same rule, g(4) would be the value of y when x = 4 which,
according to the graph, g(4) = 3
Plug these values back into the original equation to get:
