Answer:
7/15
Step-by-step explanation:
Step 1
We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.
So we multiply 4 by 3, and get 12.
Then we multiply 1 by 5, and get 5.
Next we give both terms new denominators -- 5 × 3 = 15.
So now our fractions look like this:
12
15
−
5
15
Step 2
Since our denominators match, we can subtract the numerators.
12 − 5 = 7
So the answer is:
7
15
Step 3
Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?
To find out, we try dividing it by 2...
Nope! So now we try the next greatest prime number, 3...
Nope! So now we try the next greatest prime number, 5...
Nope! So now we try the next greatest prime number, 7...
Nope! So now we try the next greatest prime number, 11...
No good. 11 is larger than 7. So we're done reducing.

Ron randomly pulls a pen out of a box that contains 1 red, 2 black, and 3 blue pens. He does
this 4 times, replacing the pen each time, but pulls out a blue pen only 1 time. Ron concludes
that the observed frequency of pulling a blue pen will eventually be closer to the expected
frequency based on the theoretical probability of pulling a blue pen. Which reasoning best
supports his conclusion?
Is it A, B, C, or D
PLEASE HELP ME :)
Answer: A
Step-by-step explanation:
I did this test before : )
The theoretical probability of pulling a blue pen based on the expected frequency will get closer to 1/2 as the no. of trials increases.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The first thing is to define each of the probabilities,
Theoretical probability is defined as a proportion that expresses the ways to be successful in the total events of an experiment.
Experimental probability is defined as the proportion of the proposed result for the number of experimental attempts.
Based on the above explanation, the reason that best supports is that; the more the experiment is repeated, the closer the experimental probability gets to the theoretical one, However, as the number of attempts increases, it tends to go more to what theoretically is what would happen.
The more experiments that are done, the more the theoretical attempts trend is marked
Hence, the Theoretical probability of pulling a blue pen based on the expected frequency will get closer to 1/2 as the no. of trials increases.

Which of the following answer choices would satisfy the inequality below? -2.74 < x < -2.35
Answer: -3pi/4
Step-by-step explanation:
-3pi/4 = -2.35619
-2.35619 is closer to 0 making it greater than -2.74 but less than -2.35 bc -2.35 is closer to 0 than -2.35619 is so.... (the greater the negative number, the less value it has)
-2.74 < -3pi/4 < -2.35

Two angles form a linear pair. The measure of one angle is z and the measure of the other angle is 2.4 times z plus 10∘ 10 ∘ . Find the measure of the smallest and biggest angle
Given:
Two angles form a linear pair.
The measure of one angle is z and the measure of the other angle is 2.4 times z plus 10°.
To find:
The measure of the smallest and biggest angle.
Solution:
Two angles form a linear pair. The measure of one angle is z.
The measure of the other angle is 2.4 times z plus 10°, i.e., [tex]2.4z+10^\circ[/tex].
We know that if two angles form a linear pair then their sum is 180 degrees.
[tex]z+(2.4z+10^\circ)=180^\circ[/tex]
[tex]3.4z=180^\circ -10^\circ[/tex]
[tex]3.4z=170^\circ[/tex]
Divide both sides by 3.4.
[tex]z=\dfrac{170^\circ}{3.4}[/tex]
[tex]z=50^\circ[/tex]
Now, the measure of other angle is:
[tex]2.4z+10^\circ =2.4(50^\circ)+10^\circ[/tex]
[tex]2.4z+10^\circ =120^\circ+10^\circ[/tex]
[tex]2.4z+10^\circ =130^\circ[/tex]
Therefore, the measure of the smaller angle is [tex]50^\circ[/tex] and the measure of the bigger angle is [tex]130^\circ[/tex].

simplify the product (2u-4)(u^2+2u-7) pls don't just give me the answer bc i know the answer but can you pls explain how you got the answer
Answer:
2 • (u - 2) • (u2 + 2u - 7)
Step-by-step explanation:
2.1 Pull out like factors :
2u - 4 = 2 • (u - 2)
Trying to factor by splitting the middle term
2.2 Factoring u2 + 2u - 7
The first term is, u2 its coefficient is 1 .
The middle term is, +2u its coefficient is 2 .
The last term, "the constant", is -7
Step 1: Multiply the coefficient of the first term by the constant 1 • -7 = -7
Step 2: Find two factors of -7 whose sum equals the coefficient of the middle term, which is 2 .
-7 + 1 = -6
-1 + 7 = 6

Jonathon kicks a kickball into the air. The height of the ball in feet can be determined using the equation h(t) = 32t - 16t^2 where t is time in seconds. To determine how long the ball is in the air, he would need to calculate what? minimum maximum y-intercept x-intercepts
Which equation is a step in finding the solution to how long the ball is in the air? h(0)=32(0)-16(0)^2
0=16t(2-t)
h(t)=-16(t-1)^2+16
h(3)=32(3)-16(3)^2

Answer:
The actual height of 1 story is 15 feet.
Step-by-step explanation:
The given scale is
2 inches = 25 ft
We know the 10 story building has a height of 12 inches, but we need the actual height of 1, that is, the height of 1 story in feet.
Let's divide to find the number of inches per story
There are 1.2 inches per story.
Now, we know , let's use the rule of three
Therefore, the actual height of 1 story is 15 feet.
Answer:
15 ft
Step-by-step explanation:
2 inches = 25 ft
12 inches = x ft
2 x 6 = 12
25 x 6 = 150
150 ft = 10 stories
150/10 = 15
Each story = 15ft

Answer:
32x - 48y
Step-by-step explanation:
when you distribute, -4 has to go to both -8x and 12y
so -4 times -8x = 32x
-4 times 12 = -48y
Final answer: 32x - 48y
A certain quadrilateral has two pairs of parallel sides. The opposite sides are equal in length. There are also 4 right angles. What is the total length of the shorter pair of sides, if the longer pair measures 16cm each, and the figure has a perimeter of 56cm?
Answer:
12 + 12 = 24
Step-by-step explanation:
P = 2L + 2W
P = 2*16 + 2W
P = 56
56 = 32 + 2W Subtract 32 from both sides
56 - 32 = 2W
24 = 2W Divide by 2
24/2 = 2W/2
12 = W
The answer you want is 2 * 12 = 24
