what is f(5) if f(x)=8x-3
Answers
Answer:
f(5)=37
Step-by-step explanation:
We have the function f(x)=8x-3,
f(5) is the value of the function f when x=5, then you have to replace f(x) with x=5,
f(x)=8x-3
f(5)=8.(5)-3

Choose the ratio you would use to convert 88 pounds to ounces remember that there are 16 ounces in 1 pound
A. 1 pound/16 ounces
B. 16 ounces/ 1 pound
C. 1 ounce/ 88 pounds
D. 88 ounces/ 1 pound
Answers
Answer:
The ratio that we use to convert 88 pound to ounces is:
B. 16 ounces/1 pound
Step-by-step explanation:
There are 16 ounces in 1 pound
i.e. 1 pound=16 ounces
88 pound=88 pound × 16 ounces/1 pound
Hence, the ratio that we used to convert 88 pound to ounces is:
B. 16 ounces/1 pound

The term population is the set containing all the people or objects whose properties are to be described. Hence, option (a) is correct.
What is Population?A community is a distinct group of people, creatures, or other objects that can be recognized for the purposes of data gathering and analysis by at least one shared trait.
The majority of the time, data is collected from samples in order to learn more about huge populations.

The length of a rectangle is 5 cm longer than its width. find the width given that the area is 36cm
Answers
Let the width of the rectangle be represented by X.
Now we can conclude we can express the length by X + 5.
The area of a rectangle can be found using the formula:
A = W × L = width × length.
Filling in the formula gives us the following:
[tex]x(x + 5) = [/tex]
Work out the parenthesis (for instance using rainbow technique).
[tex] {x}^{2} + 5x[/tex]
Now, when we've found our expression that represents the area, we can set up and solve an equation.
[tex] {x}^{2} + 5x = 36[/tex]
Subtract 36.
[tex] {x}^{2} + 5x - 36 = 0[/tex]
Factorise
[tex](x + 9)(x - 4) = 0[/tex]
Rule AB = 0, gives A = 0 or B = 0
[tex]x + 9 = 0 \\ x = - 9 \\ or \\ x - 4 = 0 \\ x = 4[/tex]
Since length can't be negative, the width of the rectangle, which was represented by x, is 4.
The answer is 4 cm.

x = (- (- 2) +/- root ((- 2) ^ 2 - 4 * 4 * (- 5))) / (2 * 4)
x = (2 +/- root (4 + 80)) / (8)

2. A wildlife refuge in South America has howler monkeys and spider monkeys. A biologist working there randomly selected eight adults of each type of monkey, weighed them, and recorded their weights in pounds.
howler monkey: {15, 16, 17, 17, 17, 17, 18, 19}
spider monkey: {12, 13, 13, 14, 14, 14, 16, 16}
(a) Calculate the median each type of monkey.
(b) Calculate the mean for each type of monkey.
(c) Calculate the MAD for each type of monkey.
(d) Calculate the means-to-MAD ratio for the two types of monkeys.
(e) What inference can be made about the weight of both types of monkeys? Explain.
Answer:
Answers
spider 14 14 1
The median of howler monkey is, 17
And, Median of spider monkey is, 14
The mean for the howler monkeys is 17 and the MAD is 0.8571.
The mean for the spider monkeys is 14 and the MAD is 1.1429.
The means-to-MAD ratio is 2.6249.
This means that on average, the number of mean absolute deviations that separate the means is 2.6. This means they are different.
Find the median of data set as;
For howler monkey;
There are 8 number of howler monkey.
Hence, Median is,
= (8/2 + 1)
= 5 th term
= 17
For spider monkey;
There are 8 number of spider monkey.
Hence, Median is,
= (8/2 + 1)
= 5 th term
= 14
To find the mean of the howler monkeys, add all of the data values and divide by 7:
= (15+16+17+17+17+17+18+19)/7
= 119/7
= 17
To find the MAD, subtract each data point from the mean; take the absolute deviation; then average these together:
= (|15-17|+|16-17|+|17-17|+|17-17|+|17-17|+|17-17|+|18-17|+|19-17|)/7
= (2+1+0+0+0+0+1+2)/7
= 6/7
= 0.8571
And, Repeating these processes for the spider monkeys:
Mean:
(12+13+13+14+14+14+16+16)/7
= 98/7
= 14
And, MAD:
= (|12-14|+|13-14|+|13-14|+|14-14|+|14-14|+|14-14|+|16-14|+|16-14|)/7
=(2+1+1+0+0+0+2+2)/7
= 8/7
= 1.1429
To find the means-to-MAD ratio, find the difference in the means and divide it by the larger MAD:
17-14=3;
Hence, We get;
3/1.1429 = 2.6249

the weight of an object on mars varies directly as the weight of the object on earth a 90 pound object on earth weighs 34 pounds on mars.if an object weighs 135 pounds on earth how much does it weigh on mars
Answers
We have been given that the weight of an object on the mars varies directly as the weight of the object on earth.
Let y be weight of an object on Mars and x be weight of an object on Earth.
[tex]\\ y=kx[/tex]
We have been given that the weight of an object on Mars is 34 pounds and weight of the same object on Earth is 90 pounds.
Putting the given values in equation we get
[tex]\\ 34=k(90)\\ \\ k=\frac{34}{90}=\frac{17}{45}[/tex]
Therefore, our equation now becomes
[tex]\\ y= \frac{17}{45}x[/tex]
Now we have been given that the weight of an object on Earth is 135 pounds and we have to find the weight of the same object on Mars,
We have been given that [tex]\\ x=135[/tex]
Putting the given values in our equation we get
[tex]\\ y= \frac{17}{45}(135)=\frac{17\cdot 135}{45}=17\cdot 3 = 51[/tex]
Therefore weight of the object on Mars will be 51 pounds.

A) (x - 5)2 + (y + 7)2 = 36
B) (x + 5)2 + (y - 7)2 = 36
C) (x - 5)2 + (y + 7)2 = 12
D) (x + 5)2 + (y - 7)2 = 12
Answers
Answer:
Option B, (x + 5)² + (y - 7)² = 36
Explanation:
The equation for a circle is (x - h)² + (y - k)² = r² where r represents the radius of the circle and the center is ordered pair (h, k).
We can then plug the given information into the formula and simplify where possible.
Center at (-5, 7), radius = 6:
[x - (-5)]² + (y - 7)² = (6)²
(x + 5) + (y - 7)² = 36, which matches option B.
Solve by factoring AKA zero product property method. If the equation has no real solutions, write no real solutions.
