Answer:
-3.21
Step-by-step explanation:
A trader claims that the proportion of stocks that offer dividends is different from 0.14. If the trader wants to conduct a hypothesis test, should they use a left-, right-, or two-tailed hypothesis test to analyze whether the proportion of stocks that offer dividends is different from 0.14? Select the correct answer below: Left-tailed test Right-tailed test Two-tailed test
Answer:
The correct option is;
Two-tailed test
Step-by-step explanation:
From the interpretation of the question statement, the trader wants to conduct a hypothesis test on the trader's claim that the proportion of stocks that offer dividends is different from 0.14
Given that the difference is hypothesized, then the null hypothesis, H₀ and the alternative hypothesis, H₁ should be written as follows;
H₀: Null hypothesis (no difference, or no change)
H₁: μ ≠ μ₀ which is hypothesizing difference which is known as a two-tailed test
The confidence level is then selected and the test statistic is calculated

Answer:
y = -6x - 8
Step-by-step explanation:
The slope(m) is -6 (rises 6, runs 1 -> 6/1, but negative because this is a negative line) and the y-intercept(b) is at -8.
For each given slope and y- intercept, complete the equation of the line. Then complete the ordered pairs that you would find on the graph of the line. (use decimal notation if necessary).

is 50.24 and 50.23 rational or irrational numbers pls explain pls pls
its easy i know but my brain hurts
Answer:
50.23 and 50.24 are both rational numbers.
Step-by-step explanation:
Rational numbers can be written like a ratio.
●Whole numbers (2, 15, 77) are rational bc just put a 1 underneath it (2/1, 15/1, 77/1) now its a ratio.
●Fractions are rational bc the fraction is exactly the ratio (1/2, 5/8, 65/111)
●Decimals that "terminate" that is end or stop are rational like your problem (50.23, 50.24) and ALSO decimals that repeat (2.33333..., 7.666666...) We can do some math on these and find the ratio that is equal to the decimal.
50.23
= 50 + 23/100
= 50•(100/100) + 23/100
= 5000/100 + 23/100
= 5023/100
50.23 is equal to 5023/100.
50.24 = 5024/100 = 2512/50 = 1256/25
Briefly, decimals that do not end either with no pattern or even with a pattern, but not repeating...they are Irrational. (pi, e, and any weird 4.531874569131187732678...no pattern, and 3.1121231234pattern but not a repeat)
Square roots of not-a-perfect square are Irrational (sqrt3, sqrt7, sqrt24) probably tmi, but hope this helps!

help I really need the answer asap
Answer:
12,000 liters
Step-by-step explanation:
Since the tank is a rectangular prism, we can easily calculate the volume using the following formula:
Volume = length x width x height
The diagram shows us that the length is 2 m and the width is 5 m. The height is the depth of the oil (1.2 m). Now, we plug these numbers in:
Volume of oil = 2 x 5 x 1.2 = 12 cubic meters.
Since 1 cubic meter = 1000 liters:
12 x 1000 = 12,000 liters

Answer: 1 gallon is 4 quarts, 2 gallons is 8 quarts, 3 gallons is 12 quarts, and 4 gallons is 16 quarts. 1 quart is 2 pints, 3 quarts is 6 pints, 6 quarts is 12 pints, and 8 quarts is 16 pints. 1 pint is 2 cups, 3 pints is 6 cups, 5 pints is 10 cups, and 9 pints is 18 cups. A swimming pool is 5,000 gallons, A juice box is 2 pints, A soup bowl is 2 cups, and a watering can is 8 quarts. In order of least to greatest is 6 pints, 18 cups, 2 gallons and 6 quarts. In the picture it shows you the work for number 5. <3
Answer:
Step-by-step explanation:1 gallon is 4 quarts, 2 gallons is 8 quarts, , and 4 gallons is 16 quarts. 1 quart is 2 pints,,so 8 quarts is 16 pints. 1 pint is 2 cups, 3 pints is 6 cups, 5 pints is 10 cups, and 9 pints is 18 cups. A swimming pool is 5,000 gallons, A juice box is 2 pints, A soup bowl is 2 cups, and a watering can is 8 quarts. In order of least to greatest is 6 pints, 18 cups, 2 gallons and 6 quarts.

write the algebraic expression that matches each graph.
20 POINTS + BRAINLEIST
Answer:
Step-by-step explanation:
The (positive) slope of the line whose domain is (-infinity, -1) is
m = rise/run = 1/1, or m = 1. The (negative) slope of the other line segment is
m = rise/run = -1/1, or m = -1.
Let's now find the equation of the line with m = 1. Using the slope-intercept form, y = mx + b, where m = +1, we get 1 = +1(-1) + b, or b = 2. Then the equation is y = x + 2 on the domain (-infinity, -1).
Now find the equation of the line with negative slope:
y = -x + b; the y-intercept is immediately evident from the graph as b = 0.
Then the desired eequation is y = -x on the domain (-1, infinity).

A cylindrical cake is made in a pan that has a diameter of 10
inches and a height of 2 inches. What is the total surface
area of the icing on the cake?
141.37 square inches
Answer:
about 141.4 square inches
Step-by-step explanation:
You want the area of icing on a cake that is 10 inches in diameter and 2 inches high.
IcingThe icing on a cake covers the lateral surface area and the area of the circular top. In terms of diameter, the sum of those areas is ...
icing area = πdh +(π/4)d² = πd(h +d/4)
icing area = π(10 in)(2 in + (10 in)/4) = π(10 in)(4.5 in)
icing area = 45π in² ≈ 141.4 in²
The area of icing on the cake is about 141.4 square inches.

Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.
