The function y = 4 is a straight line and not an exponential function.
Given, a function y = 4
now, we have to test the function is exponential or not
As, the function is a straight line graph i.e. y = 4.
Now, the function y = 4 is a straight line graph which is parallel to the x-axis.
So, the function y = 4 is not an exponential function
Hence, the function y = 4 is a straight line and not an exponential function.

Compute the probability of tossing a six sided die with sides numbered 1 through 6 and getting a 5
The probability of tossing a six-sided die with sides numbered 1 through 6 and getting a 5 is 0.166666 or 1/6.
Here in the question, we see that a six-sided die is tossed. So there will be a total of 6 outcomes.
So the sample space will be {1,2,3,4,5,6}
Of which the possible outcome of getting a 5 is 1
Let A be the event of getting a 5 on tossing a six-sided die
∴ the probability of getting a 5 on tossing a six-sided die is P(A)=1/6
∵ we know that the probability of an event is the possible outcome of the event divided by the total outcomes of that event.
So here the probability of getting a 5 is 0.166666 or 1/6.

-1/4-a-4=7/4a-3
solving equations with one unlike equations
Answer:
a = -5/11
Step-by-step explanation:
You want to solve the equation -1/4-a-4=7/4a-3.
SolutionThe first step in solving this 3-step equation can be to add the opposite of (-a) so that the variable 'a' appears only on one side of the equation:
-1/4 -a -4 +a = 7/4a -3 +a
-17/4 = 11/4a -3 . . . . . . . . . . . simplify
The second step is to add the opposite of the constant (-3) so that the constant is on one side of the equation, and the variable is on the other side.
-17/4 +3 = 11/4a -3 +3
-5/4 = 11/4a . . . . . . . . . . simplify
The third step is to multiply by the inverse of the coefficient of the variable:
(4/11)(-5/4) = (4/11)(11/4a)
-5/11 = a . . . . . . . . . . . . . . . simplify
Check-1/4 -(-5/11) -4 = (7/4)(-5/11) -3
-17/4 +5/11 = -35/44 -3
(-187 +20)/44 = (-132 -35)/44
-167/44 = -167/44 . . . . . . answer checks OK

Given that,
In the picture there is a triangle with angles 53°, 8p+10°, 2p+17°.
We have to find the p value and each of the angles also.
What is angles in triangles?While the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it, the interior angles of a triangle always add up to 180°. By deducting the angle of the target vertex from 180°, one can also determine a triangle's exterior angle.
Take the angles ,
180 degrees is the sum of the angles in an triangle.
53°+ 8p+10°+ 2p+17°=180°
10p+80°=180°
10p=180°-80°
10p=100°
p=100/10
p=10°
The value of p=10.
The angles of the triangles are:
53°
8p+10=8(10)+10=80+10=90°

Suppose a large shipment of stereos contained 18% defectives. If a sample of size 306 is selected, what is the probability that the sample proportion will differ from the population proportion by more than 6%? Round your answer to four decimal places.
The probability that the sample proportion of a large shipment of stereos will differ from the population proportion by more than 6% is 0.0063
How to get the required probabilityThe probability is calculated using z score, this is used to determine the amount of standard deviations a sample, X is from the mean
The z score is given by the formula
z = (X - μ) / σ
Definition of variables
mean, μ = p = 18% = 0.18
sample size, n = 306
standard deviation, σ
= √{(p(1 - p)) / n}
= √{(0.18(1 - 0.18)) / 306}
= √{(0.18 * 0.82) / 306}
= 0.02196
The probability
differ from the population proportion by less than 3%
|X - 0.18| > 0.06
X < 0.12 OR X > 0.24
P(z < 0.12) + P(z > 0.24 )
z score for z < 0.06
z = (0.12 - 0.18) / 0.02196
= -2.7322
p value for z < -2.7322 = 0.003146
z score for z > 0.06
z = (0.24 - 0.18) / 0.02196
= 2.7322
p value for z > 2.7322 = 1 - 0.99685 = 0.003146
The probability required = 0.003146 + 0.003146 = 0.006292 = 0.63%

The cost per mile incurred by Ernest Dorsey for driving the sports coupe for last year was $0.41.
How is the cost per mile derived?The cost per mile is the quotient of the division operation involving the total cost incurred and the driving mileage for the year.
To derive the total cost, add up the value of the car consumed (cost - current value), the annual variable, and fixed costs.
Cost of a used sports coupe last year = $8,000
The current value of the car = $6,000
Used value for the year = $2,000.00 ($8,000 - $2,000)
Yearly variable costs:Gasoline $1,589.56
Oil changes $245.98
Repairs $548.11 $2,383.65
Annual fixed Costs:Insurance $1,105.32
License $85.00 $1,190.32
Total cost for the year = $5,573.97
Driven mileage for the year = 13,569 miles

Enter your answer in the box.
Write an equation in slope-intercept form for the line that passes through (3, 1) and (1,2).
The equation of the line that passes through (3, 1) and (1,2) in slope intercept form is y = - 2 / 2 x + 5 / 2.
How to find equation of a line?The equation of a line can be represented in different form such as slope intercept form, point slope form, standard form and general form.
Therefore, let's write the equation of a line that passes through (3, 1) and (1, 2).
using slope intercept form,
y = mx + b
where
m= slopeb = y-interceptTherefore, let's find slope
m = 2 - 1 / 1 - 3
m = 1 / - 2
m = - 1 / 2
Let's find y-intercept using (1, 2)
2 = - 1 / 2(1) + b
b = 2 + 1 / 2
