Answer:
5/6
Step-by-step explanation:
On a standard 6-sided die, there is only one 2. That means that there are 5 other numbers that it could land on (1, 3, 4, 5, 6).
Using that information, the probability of it not landing on a 2 is 5 out of 6 or 5/6. This is because you must do part over whole. The "part" in this situation is the 5 "wanted" numbers, and the "whole" is 6 because there are six potential numbers that it could land on.
I hope this helps.
The probability that it will not land on a 2 is 5/6
Probability is the likelihood or chance that an event will occur.
It will land on 2, Prob (land on 2) = 1/6
It will not land on 2, the probability will be given as:
Prob (not land on a 2) = 1 - 1/6
Prob (not land on a 2) = 5/6
Hence the probability that it will not land on a 2 is 5/6

Answer:
Pennies = 80
Nickels = 160
Step-by-step explanation:
Two equations representing the relation between numbers of pennies and nickels have been given.
0.01p + 0.05n = 8.80 ---------(1)
n = 2p -----(2)
By substituting the value of n from equation (2) in equation (1).
0.01p + 0.05(2p) = 8.80
0.01p + 0.1p = 8.80
0.11p = 8.80
p = [tex]\frac{8.8}{0.11}[/tex]
p = 80
By equation (2)
n = 2×80
n = 160

Answer:
~120.4 cm
Step-by-step explanation:
Applying the Pythagorean theorem:

=> height^2 = 175^2 - 127^2
=> height^2 = 14496
=> height = sqrt(14496) = ~120.4 cm

What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
Some of the coordinates from the graph are:
(1, 18), (2, 36), and (3, 54)
Now,
The rate of change between (1, 18), and (2, 36).
Slope = (36 - 18) / (2 - 1) = 18
The rate of change between (2, 36), and (3, 54).
Slope = (54 - 36) / (3 - 2) = 18
This means,
That for every hour there is an earning of $18.

Mercury and Alcohol are two common liquids used in thermometers. The boiling point of MERCURY is 357 degree C, while its freezing point is -39 degree C; For ALCOHOL, the boiling point is 78 degree C and the freezing point is -80 degree C; It is required in a laboratory to make measurements which are in the region of -60 degree C. Which type of thermometer would be more suitable? (ASSET)
Answer:
Alcohol
Step-by-step explanation:
Alcohol would be more suitable for making measurements in a -60 degree laboratory, since its boiling point is 78 degrees and its freezing point is -80 degrees, meaning alcohol will not freeze in a -60 degree environment.
Mercury on the other hand, has a freezing point of -39. Thus, it will freeze in a -60 degree environment, making it not suitable for use in this laboratory.
The volume of a right-rectangular prism is 15 cubic feet. The prism is 2½ feet wide and has a height of ½ foot. How long, in feet, is the rectangular prism?
Answer:
12 feet
Step-by-step explanation:
To get the volume of a rectangular prism, you must multiply the height, width, and length of the prism. So to get your answer, you must multiply 2 1/2 and 1/2, then divide 15 feet by the answer. 2 1/2 × 1/2 × 12 = 15

Fifteen percent of the students at Central High take Spanish, 12% take French, and 4% take both. If a student is selected at random, what is the
probability that the student takes Spanish or French?
A 31%
B. 27%
C. 23%
D. 19%
Answer:
C. 23%
Step-by-step explanation:
At Central High
From the question, we are told that:
Spanish = 15%
French = 12%
Spanish and French = 4%
French or Spanish = unknown
Therefore, the probability that a student at random takes Spanish or French
= P(Spanish) + P(French) - P(Spanish and French)
= 15% + 12% - 4%
= 27% - 4%
= 23%

Quadrilateral OPQR is inscribed inside a circle as shown below. What is the measure of angle P? You must show all work and calculations to receive credit. (10 points) Circle N is shown with an inscribed quadrilateral labeled OPQR. O is labeled 2x degrees. P is labeled y degrees. Q is labeled 2
Answer:
The measure of angle P is 43°
Step-by-step explanation:
If a quadrilateral is inscribed inside a circle, the sum of opposite angles are always equal to 180 degrees.
The angle POR is opposite to the angle PQR, and the angle OPQ is opposite to the angle ORQ.
So we have that:
mOPQ + mORQ = 180°
y + 3y + 8 = 180
4y = 172
y = 43°
So the measure of angle P is 43°.

what is the height of the triangular prism shown above?
what is 3n+2(−2n−1)
Answer:
-n-2
Step-by-step explanation:
First, you need to distribute the 2 on the -2n and -1. So multiply the 2 by -2n and -1. You get = -4n-2.
You still have the 3n, so the equation will now look like: 3n-4n-2.
Combine like terms. 3n-4n= -1n or just -n.
Now you have -n-2.

A trapezoid has an area of 20 cm2 and a height z cm. The lengths of the parallel sides are (2z + 3) cm and (6z – 1) cm. Find the height, z, of the trapezoid. In your final answer, include all of the formulas and calculations necessary.
Answer: 2.11cm
Step-by-step explanation:
Given the following :
The lengths of the parallel sides are (2z + 3) cm and (6z – 1) cm
The area of trapezoid is calculated using the formula:
1/2(a + b) × h
Where ;
a = Length of side 1
b = length of side 2
h = height
Take a = (2z + 3) and b = (6z – 1), h = z
Therefore ;
1/2 (2z + 3 + 6z - 1) × z
Opening the bracket
(z + 1.5 + 3z - 0.5) × z
(4z + 1 ) × z = 20cm^2
4z^2 + z = 20cm^2
Using Quadratic formula:
4z^2 + z - 20 = 0
a = 4, b = 1, c = - 20
(-b±√b^2 -4ac) / 2a
Z = 2.11 or - 2.364
z cannot be negative, therefore,
Z = 2.11 cm

A cylindrical container with a radius of 6 cm and a height of 10 cm is filled with water to a depth of 6 cm. A sphere with a radius of 3 cm is placed at the bottom of the container.
a) What is the volume of the water to the nearest tenth?
b) What is the volume of the sphere to the nearest tenth?
c) How much higher does the water level rise in the container, to the nearest tenth, after the
sphere is placed inside?
Answer:
a. 452.4 cm³ to the nearest tenth b. 113.1 cm³ to the nearest tenth
c. 5.0 cm to the nearest tenth
Step-by-step explanation:
a. The volume of the water V₁ = πr²h since it is in a cylindrical container. r = 6 cm and h = 10 cm - 6 cm = 4 cm (since it is filled to a depth of 6 cm measuring from the top, so we have a height from the bottom of 10 cm - 6 cm = 4 cm).
So, V₁ = πr²h
= π × (6 cm)² × 4 cm
= 452.39 cm³
= 452.4 cm³ to the nearest tenth
b. The volume of the sphere V₂ = 4πr³/3 where r = radius of sphere = 3 cm.
V₂ = 4πr³/3
= 4π(3 cm)³/3
= 113.1 cm³ to the nearest tenth
c. When the sphere is placed in the container, the new volume of water in the container would be V = V₁ + V₂
So V = 452.4 cm³ + 113.1 cm³ = 565.5 cm³
Since the volume of water is still the volume of a cylinder, its height h is
h = V/πr²
= 565.5 cm³/π(6 cm)²
= 5.0 cm to the nearest tenth
