The angle measures 30°, 60°, 120°, and 150° are written on
slips of paper. One student chooses a slip, identifies the
type of angle, and returns the slip. A second student
chooses a slip. What is the probability that the second slip
will contain an obtuse angle measure, given the first slip
contained an acute angle measure?
A. 1/16
B. Not here
C. 1/2
D. 1/4
Answer:
c
Step-by-step explanation:
you have a 50/100 chance tyo get an obtusse angel
The probability that the second slip will contain an obtuse angle measure, given the first slip contained an acute angle measure is 3/4.
What is conditional probability ?Conditional probability is occurrence of a certain event based on the occurrence of the previous event.
According to the given question the angle measures 30°, 60°, 120°, and 150° are written on slips of paper.
One student chooses a slip, identifies the type of angle, and returns the slip.
Let A = Choosing an obtuse angle in the second time and B = Choosing an acute angle in the first draw.
Now, P(A/B) = Probability of choosing an obtuse angle when the first draw was an acute angle.
P(A) = 1/2 and P(B) = 2/3.
∴ P(A/B) = (1/2)/(2/3) = 1/2×3/2 = 3/4.

A rectangular rug feet long and wide feet wide with a perimeter of 60 ft both X and Y are whole numbers between 10 and 20
Complete Question
A rectangular rug feet is x ft long and y feet wide with a perimeter of 60 ft both X and Y are whole numbers between 10 and 20. Fill in the blanks to complete the sentence. The Area of the rug is greater than___but less than__.
Answer:
he Area of the rug is greater than but less than [tex]441ft[/tex]
Step-by-step explanation:
From the question we are told that:
Perimeter [tex]P=60ft[/tex]
Value Range:Between 10-20
Generally the Area of the rug is greater than for values of X and Y greater than 9
Therefore Area is greater than from whole number 9
Generally the equation for Area greater than [tex]A_g[/tex] is mathematically given by
[tex]A_l=X*Y[/tex]
Where
[tex]X=9\\Y=9[/tex]
Therefore
[tex]A_l=X*Y[/tex]
[tex]A_l=9*9[/tex]
[tex]A_l=81ft[/tex]
Generally the Area of the rug is less than for values of X and Y less than 21
Therefore Area is less than from whole number 21
Generally the equation for Area greater than A_l is mathematically given by
[tex]A_g=X*Y[/tex]
Where
[tex]X=21\\Y=21[/tex]
Therefore
[tex]A_g=X*Y[/tex]
[tex]A_g=21*21[/tex]
[tex]A_g=441ft[/tex]

Which best compares the phases of matter to marbles in a tray? A solid is like the tray being shaken and the marbles moving around it, and a liquid is like the tray being shaken slowly and all the marbles moving in their positions. A solid is like the tray being shaken slowly and all the marbles moving in their positions, a liquid is like the tray being shaken and the marbles moving around it, and a gas is like the tray being shaken hard and the marbles moving vigorously around it. A gas is like the tray being shaken slowly and all the marbles moving in their positions, and a solid is like the tray being shaken hard and the marbles moving vigorously around it. A liquid is like the tray being shaken hard and the marbles moving vigorously around it, and a gas is like the tray being shaken slowly and all the marbles moving in their positions.
Answer:
A solid is like the tray being shaken slowly and all the marbles moving in their positions, a liquid is like the tray being shaken and the marbles moving around it, and a gas is like the tray being shaken hard and the marbles moving vigorously around it.
Step-by-step explanation:
In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states.
Generally, matter exists in three (3) distinct or classical phases and these are;
1. Solid: it is the state of matter in which the physical substance has a definite shape and fixed volume but not compressible. Examples of solids are pen, screwdriver, television, car etc.
2. Liquid: it is the state of matter in which the physical substance can be poured and it takes the shape of its container. Also, liquids generally have a definite volume. Examples of liquids are urine, water, milk, blood etc.
3. Gas: it is the state of matter in which the physical substance has no definite shape or volume and as a result fills all available space. Also, gases are easily compressible and can flow. Examples of gases are hydrogen, oxygen, argon, nitrogen etc.
Hence, the statement which best compares the various phase of matter to marbles in a tray is that,
a. All the marbles which are solid move in their positions when the tray is shaken slowly.
b. When the tray is being shaken and the marbles moves around it, this represents a liquid.
c. When the marbles move vigorously around the tray as it's being shaken quickly, this represents the a gas or gaseous state.
Answer:
it's B.
A solid is like the tray being shaken slowly and all the marbles moving in their positions, a liquid is like the tray being shaken and the marbles moving around it, and a gas is like the tray being shaken hard and the marbles moving vigorously around it.

i just did this as guess and check.
what numbers have a difference of 5?
the factors 4 and 9.
so, if a is the negative one, a has to be -9 to get -5 because

Find the value of x in the figure shown.
Answer:
x= 17
Step-by-step explanation:
Assuming that the total degree of this side is also 90, we'll subtract 90 with 39.
90 - 39= 51
since x is 3 times the total degree, we'll divide 51 by 3, leaving us with 17.
Joanne has a ribbon 4 m long. He cuts it into 7 equal pieces. How long is each piece of ribbon? (Give the answer in fraction) Each piece of ribbon is ________
Answer:
4/7 m
Step-by-step explanation:
Joanne has a ribbon 4 m long. He cuts it into 7 equal pieces. How long is each piece of ribbon?
From the above question, we can say that:
7 pieces = 4 m
1 piece = x
Cross Mulitiply
7 × x = 1 × 4
x = 4/7 m
Therefore, the length of each piece of ribbon = 4/7 m
