Answer:
Length = [tex]13\ \text{ft}[/tex]
Width = [tex]7\ \text{ft}[/tex]
Step-by-step explanation:
Let
Breadth of the garden = x
According to the question length of the garden = 6+x
Fencing given for the rectangular garden = 27 ft
Perimeter of the garden is given by
[tex]6+x+x+x=27\\\Rightarrow 6+3x=27\\\Rightarrow x=\dfrac{27-6}{3}\\\Rightarrow x=7\ \text{ft}[/tex]
Here the garden's length will be along the garage so fencing will not done there. So length will be added only once in the perimiter.
The length of the garden is [tex]6+7 = 13\ \text{ft}[/tex] and the width is [tex]7\ \text{ft}[/tex].

10( x+1/2)=3x+5+7x
Please help
Answer:
All real numbers are solutions
Step-by-step explanation:
10(x + 1/2) = 3x + 5 + 7x
~Distribute left side
10x + 5 = 3x + 5 + 7x
~Combine like terms
10x + 5 = 10x + 5
~Subtract 5 to both sides
10x = 10x
~Divide 10 to both sides
x = x
~Subtract x to both sides
0 = 0

Answer:
the second bubble, [tex]\frac{1}{6^{2} }[/tex]
Step-by-step explanation:
[tex]6^{-2}[/tex] = [tex]\frac{1}{6^{2} }[/tex]
Answer:
1/6^2
the second one
Step-by-step explanation:
1. replace a with 6:
6^-2 6 to the power of negative two
2. solve;
when you have something to the power of a negative number, it gets smaller, so think: what is 6^2? (six to the power of two) That is 36. As a fraction, that would be 36/1. Since the 2 is negative, flip it to get 1/36.
1/6^2 and 1/36 are equal since 6^2 = 36

4) u= 6a + 2b, for a
What is the solution for A?
Answer:
a = (u-2b)/6
Step-by-step explanation:
First get a by itself by subtracting 2b from both sides:
u-2b = 6a
Then isolate the variable by dividing both sides by six:
(u-2b)/6 =a

A softball pitcher has a 0.487 probability of throwing a strike for each pitch. If the softball pitcher throws 29 pitches, what is the probability that no more than 14 of them are strikes? Insert the correct symbol to represent this probability.
Answer:
P(x≤14) = 0.556
Step-by-step explanation:
Given:
Probability of throwing a strike (p) = 0.487
Total number of throw (n) = 29
Find:
Probability that no more than 14 of them are strikes P(x≤14)
Computation:
Mean(np) = (29)(0.487)
Mean(np) = 14.123
Standard deviation = √[mean( 1- p)]
Standard deviation = √[14.123( 1 - 0.487)]
Standard deviation = 2.6917 (Approx)
P(X < x) = P[(Z < (x - mean)]/[Standard deviation])
P(x≤14) = P(Z < (14.5 - 14.123) / 2.6917 )
P(x≤14) = 0.556

AB = 4x + 6 and BC = 72 + 15. if AC = 120, find the length of segment AB.
Answer:
AB=33, x=6.75
Step-by-step explanation:
In order to solve this equation, draw a line with three points labeled A, B, and C. Then fill out what you know with the given information being AB=4x+6 and BC=72+15, then AC=120. then follow these steps:
Write the following equation: 4x+6+72+15=120Add like terms: 4x+93=120Subtract 93 from both sides, isolating the variable (x): 4x=27Divide both sides by 4 to get x=6.75Now that we know that x=6.75, follow these steps:
Plug in x to the equation: 4(6.75)+6 to find the length of AB, and the answer would be 33.I hope this helps!!!
What is f(g(x)) when f(x) = x ^ 2 + 5 , and g(x) = 10 - 5x ?
A function f (x) and g (x) then:
(f + g) (x) = x² - x + 6
Further explanation
Like the number operations we do in real numbers, operations such as addition, installation, division or multiplication can also be done on two functions.
Suppose a function f (x) and g (x) then:
(f + g) (x) = f (x) + g (x)
(f + g) (x) is a new function of the sum of f (x) and g (x)
Likewise with other function operations:
(f-g) (x) = f (x) - g (x)
(fg) (x) = f (x) x g (x)
(f / g) (x) = f (x) / g (x)
In addition to the above operations we can combine two functions using the function composition with the symbol o
(fog) (x) = f ((g (x))
Known on the question
f (x) = x² + 1
g (x) = 5 x
Summing the two functions f (x) and g (x):
(f + g) (x) = f (x) + g (x)
(f + g) (x) = x² + 1 + 5 - x
(f + g) (x) = x² - x + 6

A decision maker is interested in estimating a population proportion. A sample of size n150 yields 115 successes. Based on these sample data, construct a 90% confidence interval estimate for the true population proportion. A. (0.714, 0.826) B. (0.717, 0.823) C. (0.750, 0.790) D. (0.737, 0.803)
A. (0.714, 0.826)
Step-by-step explanation:
Given that:
The sample size n = 150
The number of success(sample proportion) x = 115
The population proportion [tex]\hat p[/tex] = [tex]\dfrac{x}{n}[/tex]
The population proportion [tex]\hat p[/tex] = [tex]\dfrac{115}{150}[/tex]
The population proportion [tex]\hat p[/tex] = 0.767
At 90% confidence interval level;
[tex]Z_{\alpha /2} = Z_{0.05} = 1.645[/tex]
Thus, the confidence interval estimate for the true population proportion can be computed by using the formula:
[tex]=\hat p \ \pm \ z_{\alpha /2} \sqrt{\dfrac{\hat p(1- \hat p)}{n} }[/tex]
[tex]= 0.767 \ \pm 1.645 * \sqrt{\dfrac{0.767(1- 0.767)}{150} }[/tex]
[tex]= 0.767 \ \pm 1.645 * \sqrt{\dfrac{0.767(0.233)}{150} }[/tex]
[tex]= 0.767 \ \pm 1.645 * \sqrt{\dfrac{0.178711}{150} }[/tex]
[tex]= 0.767 \ \pm 1.645 * \sqrt{.0011914}[/tex]
[tex]= 0.767 \ \pm 1.645 * 0.03452[/tex]
[tex]= 0.767 \ \pm 0.0568[/tex]
= (0.767 - 0.0568, 0.767 + 0.0568)
= (0.7102 , 0.8238 )
Due to approximation; the confidence interval estimate for the true population proportion is [tex]\simeq[/tex] (0.714, 0.826)
The measure of an angle in standard position is given. Find two positive angles and two negative angles that are coterminal with the given angle. (Enter your answers as a comma-separated list.)
Answer:
The answer is below
Step-by-step explanation:
Let us assume the angle is -π/4.
Coterminal angles are angles that have the same initial side and terminal side. They are angles in standard position (angles with the initial side on the positive x -axis) that have a common terminal side.
Positive coterminal angles are gotten by adding 360° if the angle is in degrees or 2π for angles in radian while negative coterminal angles are gotten by subtracting 360° if the angle is in degrees or 2π for angles in radian.
Positive coterminal angle = -π/4 + 2π = 7π/4, 7π/4 + 2π = 15π/4
Positive coterminal angle = 7π/4, 15π/4
Negative coterminal angle = -π/4 - 2π = -9π/4, -9π/4 - 2π = -17π/4
Negative coterminal angle = -9π/4, -17π/4

4. Calculate the probability that an officer is promoted given that the officer is a man. 5. Calculate the probability of a promotion given that the officer is a woman
Answer:
4. Probability of being promoted given the officer is a man = 0.3
5. Probability of a promotion given that the officer is a woman = 0.15
Note: The data table is found in the attachment below
Step-by-step explanation:
Probability = number of required outcomes/ number of possible outcomes
4. Probability of being promoted given the officer is a man
Probability of being promoted given the officer is a man = number of men promoted/total number of men
From the table, total number of men = 960
number of men promoted = 288
Probability of being promoted given the officer is a man = 288/960 = 0.3
5. Probability of a promotion given that the officer is a woman
Probability of a promotion given that the officer is a woman = number of women promoted/total number of women
From the table, total number of women = 240
number of women promoted = 36
Probability of a promotion given that the officer is a woman = 36/240 = 0.15
