Answer:
[tex]\frac{1}{4} * 3 = \frac{3}{4}[/tex]
Because:
[tex]\frac{1}{4} * 3 = \frac{1}{4} +\frac{1}{4} + \frac{1}{4}[/tex]
Step-by-step explanation:
Given
[tex]\frac{1}{4} * 3 = [\ ][/tex]
Because
[tex]\frac{1}{4} * 3 = [\ ] + [\ ] + [\ ][/tex]
Required
Fill in the box
[tex]\frac{1}{4} * 3 = [\ ][/tex]
This can be written as:
[tex]\frac{1}{4} * 3 = \frac{1* 3 }{4}[/tex]
Solve the numerator
[tex]\frac{1}{4} * 3 = \frac{3}{4}[/tex]
(b) Because
[tex]\frac{1}{4} * 3 = [\ ] + [\ ] + [\ ][/tex]
The above implies that
[tex]\frac{1}{4}[/tex] be added in 3 places
i.e.
[tex]\frac{1}{4} * 3 = \frac{1}{4} +\frac{1}{4} + \frac{1}{4}[/tex]

What percentage of values are between 25 and 45
Answer:
I'm not that good at this but I'll try.
The difference between 25 and 40 is 15
The difference between 80 and 5 is 75
So, 15/75 = 0.20 or 20%

Step-by-step explanation:
Let $p be the original price.
[tex](1 - 25\%)p = 30 \\ \frac{75}{100}p = 30 \\ p = 40[/tex]
∴ The original price is $40.
Please help meeee! A new crosswalk is being built between the parallel sidewalks of Circle Avenue. The edges of the crosswalk are parallel. One angle that the crosswalk makes with the sidewalk measures 78 degrees, as shown. Determine the measures of the missing angles. The drawing is not drawn to scale.
Answer:
[tex]A = 78^\circ[/tex]
[tex]B = 102^\circ[/tex]
[tex]C = 102^\circ[/tex]
Step-by-step explanation:
Given
The attached image
Required
Find A, B and C
Because the sides of the crosswalk are parallel and the sidewalks are also parallel, then the following relationships exist
[tex]A = 78^\circ[/tex] ---- alternate interior angles
[tex]B = C[/tex] ---- alternate interior angles
To solve for B, we have:
[tex]B + 78 = 180[/tex] --- the sum of the base angles
[tex]B = 180 - 78[/tex]
[tex]B = 102^\circ[/tex]
Recall that:
[tex]B = C[/tex]
[tex]C = 102^\circ[/tex]

The distance between two cities on a map is 3.5 centimeters. The map uses a scale in which 1 centimeter represents 20 kilometers. What is the actual distance between these two cities in kilometers?
Answer:
70kilometers
Step-by-step explanation:
first we must find how much one half of a centimeter is
well, its easy, theres already a half for the distance, and the representation is an even number, so cut it in half.
20-10 is 10
and now the multiplication
20x3=60
60+10=70

You wonder what is the average number of credits Le Moyne students take per semester. You speak with the Le Moyne registrar, and they tell you that Le Moyne students take an average of 17 credits per semester with a population standard deviation of 2.5 credits. We plan to take a sample of 49 students and ask each student how many credits they plan to take. Assume that the population mean is 17 credits and the populations standard deviation is 2.5 credits. What does the CLT say about the distribution of the sample mean of 49 students
Answer:
The CLT says that the distribution is approximately normal, with mean of 17 credits and standard deviation of 0.3571 credits.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Assume that the population mean is 17 credits and the populations standard deviation is 2.5 credits.
This means that [tex]\mu = 17, \sigma = 2.5[/tex]
What does the CLT say about the distribution of the sample mean of 49 students?
It is approximately normal.
The mean is 17.
Due to the sample of 49, n = 49, and the standard deviation is [tex]s = \frac{2.5}{\sqrt{49}} = 0.3571[/tex]
The CLT says that the distribution is approximately normal, with mean of 17 credits and standard deviation of 0.3571 credits.

Question: Edwin usually makes 20 cookies with this recipe, but only wants 5 cookies.
How much is 1/2 teaspoon of vanilla to make 5 cookies?
(PLEASE HELP!!)
the wrong answers that u guessed just to get points and links and other stuff that is not answering this will be reported
Answer:
1/2 teaspoons of vanilla would be too much, the correct amount to use would be 0.125 teaspoons.
Step-by-step explanation:
Since 1 stick butter, 1/2 cup sugar, 1/2 teaspoon vanilla, 3 tablespoons milk, 1 1/2 cup flour, 2 teaspoon baking powder, 1/4 teaspoon salt is the regular recipe for 20 cookies, we would first have to divide 20 by 5 which would equal 4. And just like we had to divide the number of cookies down we have to divide the amount of vanilla down. So now we could turn 1/2 into a decimal which is 0.5. And 0.5 divided by 4 is 0.125.
So Edwin would need 0.125 teaspoons of vanilla so 0.5 ( 1/2 ) teaspoons of vanilla would be too much.
If g(x) = 1/4X-4 find
g(-4) = [g1]
g(12) = [g2]
Answer:
G1 = -5 G2 = -1
Step-by-step explanation:
plug in the values given into X and solve
g1= 1/4(-4) -4
g1 = -1 -4
g1 = -5
g2= 1/4(12) -4
g2= 3 -4
g2= -1
(PLEASE HELP) A teacher surveyed a sample of students from Lake Middle School. He asked the students where they'd like to go for a field trip. He recorded these results:
• 80 chose the aquarium.
• 60 chose the science center.
• 30 chose the planetarium.
• 40 chose the farm.
The teacher wants to figure out the relative frequency of a student choosing the aquarium. He'll then estimate how many students out of all 1000 at the school are likely to choose the aquarium.
(he surveyed 210 students and about 38% of them chose the aquarium)
Write and solve a proportion that the teacher can use to estimate how many students in the whole school would choose the aquarium.
Answer:
relative frequency of choosing aquarium is 80/210
about 400 students out of 2000 will choose aquarium
Step-by-step explanation:
relative frequency of choosing aquarium is 80/210
proportion:
a = students who choose aquarium
80/210 = a/1000
210a = 80000
a = 80000/210 which is close to 80000/200 which equals 800/2 or about 400 students
