Two thirds of a number decreased by eighteen is negative twenty-four.
Answer:
Step-by-step explanation:
Let the number be x
Two thirds of the number is expressed as ;
[tex]\frac{2}{3} * x\\\frac{2x}{3}[/tex]
The number decreased by 18:
[tex]\frac{2x}{3} - 18[/tex]
If the resulting value is equal to 24;
[tex]\frac{2x}{3} - 18 = 24[/tex]
solve the resulting expression for x
[tex]\frac{2x}{3} - 18 = 24\\\frac{2x}{3} = 24+18\\\frac{2x}{3} -= 42\\2x = 3*42\\x = 126/2\\x = 63[/tex]
Hence the unknown number is 63

Answer:

Step-by-step explanation:
Fishermen fishing for spiny lobster are allowed to keep only lobsters with a carapace length of 3.25 inches or longer. (Than carapace length is measured from the rear edge of the eye socket to the rear edge of the body shell.) Any lobster smaller than 3.25 inches must be returned to the sea. Suppose that lobster carapace lengths have a distribution that is mound shaped and approximately symmetric with a mean of 5.50 inches and a standard deviation of 2.25 inches. Approximately what proportion of lobsters will have to be returned to the sea
Answer:
16%
Step-by-step explanation:
First we start by solving for the z score
We have the following information
x = 3.25
Standard deviation = sd = 2.25
Mean = 5.50
Z = (x - mean)/sd
z = 3.25 - 5.50/2 25
z = -1.00
If we look this up in the standard normal distribution table,
P(z<-1.00) = 0.1587
Which when approximated gives us
16%
Therefore approximately 16% of lobsters will have to be returned back to the sea.

which of the following numbers is rational but not an integer
A.0
B.3
C.-9
D.-4.3
Answer:
Thus, every integer is a rational number. Clearly, 3/2,-5/3, etc. are rational numbers but they are not integers. Hence, every integer is a rational number but a rational number need not be an integer.
Step-by-step explanation:
Place parentheses around the expression from the previous problem so when simplified it is equal to 13.
15 - 6 + 1 +30 ÷ 3 × 2 (This is the expression from the previous problem just to clarify.)
Answer: 15 - (6 + 1) + 30 ÷ (3 × 2)
Step-by-step explanation:
The simplest way is just to [try check and revise]. Place parentheses on each two numbers and try.
However, there is a somewhat trick involved.
Normally, when a question asks for adding parentheses, the parentheses are normally placed on two numbers that don't usually operate together.
For example, in this question, [15 - 6 + 1]. Normally, is should be 15-6 which is 9. Then 9+1 is 10. Also, usually when you add parentheses on -6+1, it will change signs into -(6-1). But, in this question, when we add parentheses, signs don't change. So it is -(6+1).Hope this helps!! :)
Answer:
15 - (6 + 1) + 30 ÷ (3 × 2)
Step-by-step explanation:
when is the appropriate to model data with a linear function. give example of a real world data that can modeled with a linear function include the linear function example of the data
Answer:
You can model a data using a linear function when the dependent variable is a multiple of the independent formula plus another constant by the y-intercept. The constant multiple is represented by the slope. In real life problems, linear function is applied when you want to determine the cost given with a slope which is represented by cost per unit time. For example, the cost of wifi connection is $10/month plus $2 inclusive for phone charges. The linear function would be:
C = 10t + 2
where C is the cost and t is time in months
Step-by-step explanation:
In a room shaped like an ellipse, something whispered at 1 focus can be clearly heard at the other focus. The U.S. Capitol National Statuary Hall in Washington, D.C. is such a whispering gallery. From 1807 to 1857, the U.S. House of Representatives met in this room. According to legend, when John Quincy Adams was a representative following his presidency, he used to look as though he was asleep at his desk during debate, but he was listening to what representatives of the opposing party on the other side of the room were whispering. If the elliptical pattern of this whispering gallery is 92 feet long by 58 feet wide, how far from the whisperer at 1 focus is the listener at the other focus
Answer:
The listener is approximately 71.414 feet far from the whisperer.
Step-by-step explanation:
We must remember that two fundamental variables for every ellipse are the major semiaxis ([tex]a[/tex]) and the minor semiaxis ([tex]b[/tex]). The major semiaxis equals a half of the length of the whispering gallery, whereas the minor semiaxis equals a half of the width of the whispering gallery. These are:
[tex]a = 46\,ft[/tex] and [tex]b = 29\,ft[/tex]
The distance between both whisperers ([tex]d[/tex]), measured in feet, is two times the distance between center and any of the foci ([tex]c[/tex]), measured in feet, whose valued is obtained by using this Pythagorean identity:
[tex]d = 2\cdot c[/tex]
[tex]c = \sqrt{a^{2}-b^{2}}[/tex]
If [tex]a = 46\,ft[/tex] and [tex]b = 29\,ft[/tex], then:
[tex]c = \sqrt{(46\,ft)^{2}-(29\,ft)^{2}}[/tex]
[tex]c \approx 35.707\,ft[/tex]
[tex]d = 2\cdot (35.707\,ft)[/tex]
[tex]d = 71.414\,ft[/tex]
The listener is approximately 71.414 feet far from the whisperer.

Which is an x-intercept of the continuous function in the
table?
O (-1,0)
O (0, -6)
O (-6, 0)
O (0, -1)
Answer:
(-1, 0)
Step-by-step explanation:
output = 0 the function’s graph will have an x-intercept
The solution is : (-1, 0), (2, 0), (3, 0) are the x-intercepts of the continuous function f(x).
What are x-intercepts of quadratic function?The zero of the function is where the y-value is zero. The zero of a function is any replacement for the variable that will produce an answer of zero. Graphically, the real zero of a function is where the graph of the function crosses the x‐axis; that is, the real zero of a function is the x‐intercept(s) of the graph of the function.
here, we have,
we know that,
x-intercept of a line is defined by a point where y = 0.
So the point in the form of (x, 0) will be the x-intercept of the given continuous function.
From the table attached,
For x = -1, f(-1) = 0
For x = 2, f(2) = 0
For x = 3, f(3) = 0
Points (-1, 0), (2, 0) and (3, 0) are the x-intercepts of the continuous function f(x).

If p-1 is a factor of p^4-p^2-p-k, the value of k is
Use the remainder theorem: it says that if x - c is a linear factor of a polynomial f(x), then the remainder upon dividing f(x) by x - c is equal to f(c).
In this case,
f(p) = p⁴ - p² - p - k
and p - 1 is a factor of f(p). We have
f (1) = 1⁴ - 1² - 1 - k = -(k + 1)
Because p - 1 divides f(p), the remainder is 0, which means
-(k + 1) = 0
k + 1 = 0
k = -1

Answer:
19 and 29/32 or 19.90625
Step-by-step explanation:
So the 1st Way: We could simplify it and make them into improper fraction in a way like this:
13/4 * 49/8
We can then just multiply the top row and the bottom row:
13 * 49 = 637
4 * 8 = 32
637/32 = 19 and 29/32
The 2nd Way: We could literally add 6 and 1/8, 3.25 times
(I'm so sorry this is a way lol but I couldn't think of another)
6.125 + 6.125 + 6.125 + 6.125(0.25) = 18.375 + 1.53125 = 19.90625 :P

Multiply the denominator by the whole number and whatever you get you to add the numerator with it and that is how you make it improper.
The radius of a cylinder water tank is 4 ft, and its height is 12 ft. What is the volume of the tank?
Use the value 3.14 for it, and round your answer to the nearest whole number.
Be sure to include the correct unit in your answer.
Answer:
The answer is 603 ft³Step-by-step explanation:
Volume of a cylinder is given by
[tex]V = \pi {r}^{2} h \\ [/tex]
where
r is the radius
h is the height of the cylinder
From the question
r = 4 ft
h = 12 ft
π = 3.14
So we have
[tex]V = (3.14) ({4})^{2} (12) \\ = (3.14)(16)(12) \\ = 602.88[/tex]
We have the final answer as
603 ft³ to the nearest whole number
