Answer:
Radius:3.5 or 7/2
Diameter:7
Step-by-step explanation:
The diameter is given, and the radius is half of the diameter because it's from the middle of the circle to the edge. Divide 7 by two and you get radius

Chicken Delight claims that 92% of its orders are delivered within 10 minutes of the time the order is placed. A sample of 85 orders revealed that 74 were delivered within the promised time. At the 0.05 significance level, can we conclude that less than 92% of the orders are delivered in less than 10 minutes?
Answer:
Kindly check explanation
Step-by-step explanation:
H0 : π ≥ 0.92
H1 : π < 0.92
At α = 0.05
Left tail
Z0.05/2 = Z0.025 = - 1.645
The test statistic
Zstatistic :
(m - p) / σ
Sample size, n = 85
m = 74/85 = 0.87
p = 0.92
σ = sqrt(p(1 - p) /n)
σ = sqrt(0.92(1 - 0.92) / 85)
σ = sqrt(0.0008658)
σ = 0.0294258
σ = 0.0294
Zstatistic :
(m - p) / σ
(0.87 - 0.92) / 0.0294
Zstatistic = −1.700680
Zstatistic = - 1.70
Decision region :
Reject H0: if ;
Zstatistic < Zcritical
-1.70 < - 1.645
Since,
Zstatistic < Zcritical ; then Reject H0.
If twice a number added to 3 is divided by the number plus 6, the result is three halves. Find the number.
Answer:
3/2
Step-by-step explanation:
Let x be the unknown number.
If twice a number added to 3: 2x+3
is divided by the number plus 3: (2x+3)/3
the result is three halves: (2x+3)/3 = 3/2
(2x+3)/3 = 3/2
Multiply both sides by 3:
2x + 3 = 9/2
Subtract 3 from both sides:
2x = 9/2 - 3 = 9/2 - 6/2 = 3/2
Divide both sides by 2:
x = 3/4
Check:
(2x+3)/3 = 3/2
(2*(3/4)+3)/3 = 3/2
(6/4 + 3)/3 = 3/2
(18/4)/3 = 3/2
6/4 = 3/2
3/2 = 3/2

What is an equation of the line that passes through the point (-5 7) and is parallel to the line x-5y=15
Answer:
Step-by-step explanation:
Parallel lines have same slope.
y = mx + b
Slope = m & y-intercept = b
x - 5y = 15
-5y = -x + 15
y = [tex]\frac{-1}{-5}x + \frac{15}{-5}\\\\[/tex]
[tex]y = \frac{1}{5}x - 3[/tex]
so, slope = 1/5 ; (-5 , 7)
y -y1 = m(x -x1)
[tex]y - 7 = \frac{1}{5}(x- [-5])\\\\y - 7 =\frac{1}{5}(x + 5)\\\\y - 7 = \frac{1}{5}x+5*\frac{1}{5}\\\\y - 7 =\frac{1}{5}x+1\\\\y =\frac{1}{5}x+1+7\\\\y=\frac{1}{5}x + 8[/tex]

Starting at a fixed time, each car entering an intersection is observed to see whether it turns left (L), right (R), or goes straight ahead (A). The experiment terminates as soon as a car is observed to turn left. Let X = the number of cars observed. What are possible X values? List five different outcomes and their associated y values.
Answer:
Outcomes are { L, RL, AL, RAL, ARL }
Associated X values are { 1, 2, 2, 3, 3 }
Step-by-step explanation:
As given,
left = (L),
right = (R)
goes straight ahead = (A)
Now,
The Sample space become = { L, RL, AL, RAL, ARL }
In L -
Number of cars = 1
In RL-
Number of cars = 2
In AL-
Number of cars = 2
In RAL-
Number of cars = 3
In ARL-
Number of cars = 3
what is 6(-5n + 7) simplified?
Answer:
-30n+42
Step-by-step explanation:
You have to use distributive property.
Multiply 6 with -5n which is -30n. Then, Multiply 6 with 7 which is 42. Since, 5n is negative the product is also negative, and since 7 is positive the product is positive. Therefore you will get, -30n+42.
I hope this helps!
Could I get brainliest? ✨
The simplified form of 6(-5n + 7) is -30n + 42.
To simplify the expression 6(-5n + 7), we apply the distributive property. The distributive property states that when we multiply a number outside the parentheses by an expression inside the parentheses, we must multiply it by each term inside the parentheses.
In this case, we have 6 multiplied by the expression (-5n + 7).
Multiplying 6 by -5n gives us -30n, and multiplying 6 by 7 gives us 42.
So, combining these results, we get -30n + 42.
This simplified expression, -30n + 42, cannot be further simplified because there are no like terms to combine.
Therefore, 6(-5n + 7) simplifies to -30n + 42.

Name Each of the vertices on the quadrilateral
The names of the vertices (or corners) are the letters next to them. However you may need to write the plot points, so you would look at the left side or the y axis and count where the dot is as a number. Lets say its D. D is 4 on the y axis. Then you would go straight down to find the x axis. It is right over three. than you would write it with the x axis ALWAYS first. So D is (3,4).

What do you do with negative exponent?
Answer:
this says that negative exponents in the numerator get moved to the denominator and become positive exponents. Negative exponents in the denominator get moved to the numerator and become positive exponents. Only move the negative exponents.
¯\_(ツ)_/¯
Answer:
Negative exponents are a way of writing powers of fractions or decimals without using a fraction or decimal. You use negative exponents as a way to combine expressions with the same base, whether the different factors are in the numerator or denominator. It’s a way to change division problems into multiplication problems.
Step-by-step explanation:
A negative exponent helps to show that a base is on the denominator side of the fraction line. In other words, the negative exponent rule tells us that a number with a negative exponent should be put to the denominator, and vice versa.

convert the rectangular coordinates (3,4) into polar coordinates
Answer:
(5,53°) or (5,53.13010235°) if you want an exact value.
Step-by-step explanation:
Polar coordinate is in [tex]\displaystyle{(r,\theta)}[/tex] form and rectangular coordinate is in [tex]\displaystyle{(x,y)}[/tex] form.
To convert from rectangular coordinate to polar coordinate, you’ll have to know that:
[tex]\displaystyle{x=r\cos \theta}\\\displaystyle{y=r\sin \theta}[/tex]
Above is crucial when it comes to converting from rectangular coordinate to polar coordinate, or other way around. The thing is to convert from rectangular to polar, you’ll also have to know radius too which you can find by:
[tex]\displaystyle{r=\sqrt{x^2+y^2}}[/tex]
We know that x = 3 and y = 4, substitute in the formula:
[tex]\displaystyle{r=\sqrt{3^2+4^2}}\\\\\displaystyle{r=\sqrt{9+16}}\\\\\displaystyle{r=\sqrt{25}}\\\\\displaystyle{r=5}[/tex]
We know that radius is 5. We will have to find the theta next, first substitute in the conversion:
[tex]\displaystyle{3=5\cos \theta}\\\displaystyle{4=5\sin \theta}[/tex]
Since this can generally be found through calculator as it’s not a part of special triangle - can be found using hand method - The approximation of both theta’s values are 53°.
Hence, the polar coordinate is (5,53°) or (5,53.13010235°) if you want an exact value.
