Answer:
2,5 appeared LESS
Step-by-step explanation:
the theoretical probability in this case would be 5 because Micah rolled the number cube 30 times and there is 6 total outcomes of the number cube.
To figure out the theoretical probability:
30 divided by 6
= 5
So every number that appeared less than 5 is your answer
I believe the answer is 2,5

Which triangle is NOT labeled correctly
WILL MARK BRAINLIEST!!!
red triangle
hypotenuse is the longest side of the right triangle; the opposite of the right angle
round 0.232 to the nearest hundreth
Answer:
0.23
Step-by-step explanation:
The first spot to the right of the decimal is the tenths place. Ex. .0
The second spot to the right of the decimal is the hundredths place. Ex. .00
The third spot to the right of the decimal is the thousandths place. Ex. .000
Since you are trying to round to the nearest hundredth you look at the thousandths place. If it is 5 or higher you round up. If it is under 5 you round down.
0.232
Since the 2 is the thousandths place the hundredths stays the same and you drop the thousandths place.

Jason inherited a piece of land from his great-uncle. Owners in the area claim that there is a 45% chance that the land has oil. Jason decides to test the land for oil. He buys a kit that claims to have an 80% accuracy rate of indicating oil in the soil. What is the probability that the land has no oil and the test predicts it has oil?
Answer:
Don't take my word for it but I think it would be 55% chance. I'm Probably wrong.
Step-by-step explanation:
Answer:
9% or 0.09
Step-by-step explanation:
Given, chance of land having oil is 45%. Which is 0.45
So, chance of land NOT having oil is percent. Which is 0.55
Given, kit's accuracy rate of finding oil as 80%. Which is 0.80
So, kit's accuracy rate of NOT finding oil is percent. Which is 0.20
These 2 events are INDEPENDENT, which means that the probability of one event occurring does not affect the probability of another event occuring.
The formula, if we let the two evens be A and B, is:
P(A and B)=P(A) * P(B)
Now, "the probability that the land has oil (event A)AND the test predicts that there is no oil (event B)" will be:
P(A and B) = P(A) * P(B)
Hence, the probability is 0.09 or 9%

Dawn has 1.20 in nickels, dimes and quarters. For each nickel she has one dime and for each dime she has one quarter. How many total coins does she have?
Answer:
9
Step-by-step explanation:
"For each nickel, she has one dime"
That means she has the same number of nickels and dimes.
"for each dime she has one quarter"
That means she has the same number of quarters and dimes.
She has the same number of each coin.
Let's say she has x coins of each type.
The nickels are worth 0.05x; the dimes are worth 0.10x. The quarters are worth 0.25x. Altogether, the coins are worth
0.05x + 0.10x + 0.25x
We are told her coins are worth $1.20, so we set those two amounts equal and solve for x.
0.05x + 0.10x + 0.25x = 1.20
0.40x = 1.20
x = 1.20/0.40
x = 3
She has 3 coins of each type. Since there are 3 types of coins, she has 9 coins.
Dawn has a total of 9 coins, which include 3 nickels, 3 dimes, and 3 quarters.
Explanation:The subject of this question is a math problem involving counting coins. In this scenario, dawn has a total of $1.20 in nickels, dimes, and quarters. And the number of nickels, dimes and quarters are equal since for every nickel Dawn has, she also has a dime and a quarter.
Now, the value of a nickel is $0.05, a dime is $0.10 and a quarter is $0.25. So, the total value of a nickel, a dime and a quarter is $0.40. Therefore, since the total amount of money she has is $1.20, we divide that amount by the total value of each group of coins: $1.20 / $0.40 gives us 3.
So Dawn has 3 nickels, 3 dimes, and 3 quarters, for a total of 9 coins.

What is the slope of the line through the points (–2, –1) and (8, –3)?
-3 + 1 = -2
8 + 2 = 10
-2/10 = -1/5
Answer = -1/5
The slope of the line through the points (2, 1) and (8, 3) is calculated using the slope formula and is -1/5.
To find the slope of a line passing through two points, you will need to use the slope formula, which is:
(change in y) / (change in x)or (y2 - y1) / (x2 - x1).
For the points given (–2, –1) and (8, –3), you would calculate the slope as follows:
Slope (m) = (-3 - (-1)) / (8 - (-2)) = (-3 + 1) / (8 + 2) = (-2) / (10) = -1/5.
So, the slope of the line through the points (–2, –1) and (8, –3) is -1/5.
A flag measures 110 feet by 55 feet. Find it’s area
Answer:
6050
Step-by-step explanation:
Area = length * width
Area = 110 * 55
Area = 6050
Answer:
6050 sq ft (or you could write 6050ft and a little two at the top right next to it at the end)
Step-by-step explanation:
To find the area of something, you must multiply length x width, so in this situation, you would multiply

Prediction for the number of unsuccessful rolls is 15.
Step-by-step explanation:There is [tex]\frac{1}{6}[/tex] chance of rolling number 6 on the cube. If we want to find out what is the prediction for rolling number 6 in 18 rolls, we need to multiply [tex]6*\frac{1}{6}[/tex] which is 3. So if we roll a cube 18 times, we will probably got number 6 three times. When we subtract 3 from 18 (18-3), we get 15. That is the answer to your question.

(\) QueTooOfficial (/)he front of an A-frame house is in the shape of a triangle.The height of the house is 20 feet.The area of the A-frame is 600 square feet.Write and solve an equation to find the base of the A-frame house.
Answer:
Equation: [tex]600=\frac{20b)}{2}[/tex]
Base: 60 feet.
Step-by-step explanation:
The formula for calculate the area of a triangle is:
[tex]A=\frac{bh}{2}[/tex]
Where:
A: is the area of the triangle.
b: is the base of the triangle.
h: is the heigth of the triangle.
Knowing the area of the triangle and its height, you can write the equation:
[tex]600=\frac{20b}{2}[/tex]
Where b is the base in feet of the A-frame house.
To solve it:
Multiply both sides of the equation by 2.
Divide both sides of the equation by 20.
Then:
[tex](2)(600)=(\frac{20b}{2})(2)\\\\1200=20b\\\\\frac{1200}{20}=\frac{20b}{20}\\\\60=b[/tex]
The base of the A-frame house is 60 feet.

An internet service provider is implementing a new program based on the number of connected devices in each household. Currently, customers are charged a flat rate of $175 per month. The new plan would charge a flat rate of $94 plus an additional $4.50 per device connected to the network. Find and graph the number of devices, x, for which the cost of the new plan is less than the current plan.
Answer:
n < 18
Step-by-step explanation:
The condition you are looking for is that
94 + 4.50n < 175
Subtract 94 from each side 4.50n < 81
Divide each side by 4.50 n < 18
The number of devices must be fewer than 18 for the new plan to cost less than the current plan.
The diagram is a graph of the inequality 94 + 4.50n < 175. Any value of n less than 18 (that is, in the pink zone and not on the vertical dashed line) will satisfy the inequality.

Answer:
9cos(46x) + 9cos(12x)
Step-by-step explanation:
18cos(29x)cos(17x)
According to Product-Sum identities
cos(α)cos(β)= (1/2)[cos(α+β)+cos(α-β)]
Putting α=29x and β=17x in Product-Sum identity we get
= 18×(1/2)[cos(29x+17x)+cos(29x-1`7x)]
Dividing 18 by 2 we get 9
= 9[cos(46x)+cos(12x)]
Multiplying 9 with both the terms we get

Check the picture below.
the idea being, the winding path is made out of semi-circles, each semi-circle has a diameter of 3, as you see there in the picture.
now, if we could just take two semi-circles, we'd have a full circle, with a diameter of 3, so from all 4 semi-circles we can actually get two full circles, as you see there, and the circumference of those two full circles, is the length of the winding path.

Answer:
The volume of the dirt in the flowerbed is [tex]1,056\ in^{3}[/tex]
Step-by-step explanation:
we know that
To find the volume of the dirt in the flowerbed, multiply the long by the width by the depth
so
[tex]V=(22)(8)(6)=1,056\ in^{3}[/tex]
Final answer:
To calculate the volume of dirt in a rectangular flowerbed with dimensions of 22 inches by 8 inches by 6 inches, use the formula Volume = length × width × height, resulting in 1056 cubic inches.
Explanation:
The question asks for the volume of dirt a rectangular flowerbed can hold. To find the volume, we use the formula Volume = length × width × height. Given the dimensions are 22 inches (length) by 8 inches (width) by 6 inches (height), we calculate the volume as:
Volume = 22 in. × 8 in. × 6 in. = 1056 cubic inches. Therefore, the volume of the dirt in the flowerbed is 1056 cubic inches.
