team continued to win at this rate and won w
games in the 28-game season. Which of the
following proportions could be used to determine w?
Answers
Answer:
5/7=W/28

Answer:
No, they are the same triangles
Step-by-step explanation:
They both have a side length of 3 and 5 and an angle that measures 60 degrees. The triangles are just flipped in different directions.
If they were to draw an additional triangle that would make it seem different, they could expand the angle and make it obtuse to get a triangle with 1 wide corner.
The weight of oranges growing in an orchard is normally distributed with a mean weight of 5.5 oz. and a standard deviation of 1 oz. Using the empirical rule, determine what interval would represent weights of the middle 68% of all oranges from this orchard.
pleaseeee help me now, im taking a test and it's timed
Answers
This is bevause 1 standard deviation contains 34% of the sample in a normal distribution, so 1 standard deviation on either side is 68% and so you +\- 1 oz from the mean.

A watercolor painting is 25 inches long by 12 inches wide. Ramon makes a border around the watercolor painting by making a mat that adds 3 inches to each side of the length and the width. What is the area of the mat?
Answers
Answer:
the area of the mat = total area added minus the original area of the water color painting.
Step-by-step explanation:
length of the mat is:L = 20 in + 1 in + 1 in because 1 in is added to each sideL = 22 inwidth of the mat is:w = 9 in + 1 in + 1inw = 11 in
Area mat = (22 in x 11 in) - ( 20 in x 9 in)
area mat = 62 sq in is the area of the mat
Someone please help asap!!! It’s due in 45 minutes, how am I supposed to know where to shade when doing these?
Answers
Answer:
If you want to know the process on how to graph and shade, start by graphing the inequalities. Assume that the inequality signs are just =, so the equation is y=mx+b. Let's use 1) as an example. When the sign is < or >, it's a dotted line. If the sign is ≥ or ≤, it's a solid line. Once you're done graphing the inequalities, choose a random coordinate on the graph. Let's use (0,0). Now, plug in the x- and y-value into the equations. 0<-6(0)+3 and 0≤0-2. Simplify it to get 0<3 and 0≤-2. Because the inequality is true for y<-6x+3, you would shade the side of the graph that includes (0,0). Because the inequality isn't true for y≤-x-2, you would shade the side of the graph that doesn't include (0,0). The shaded parts of both inequalities should overlap somewhere and that's the area you need to officially shade.
Here's the worked example:

Evaluating probability: A particular type of mouse's weights are normally distributed, with a mean of 726 grams and a standard deviation of 23 grams. If you pick one mouse at random, find the following: (round all probabilities to four decimal places) a) What is the probability that the mouse weighs less than 722 grams
Answers
Answer:
0.4325 = 43.25% probability that the mouse weighs less than 722 grams
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 726 grams and a standard deviation of 23 grams.
This means that [tex]\mu = 726, \sigma = 23[/tex]
a) What is the probability that the mouse weighs less than 722 grams
This is the p-value of Z when X = 722. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{722 - 726}{23}[/tex]
[tex]Z = -0.17[/tex]
[tex]Z = -0.17[/tex] has a p-value of 0.4325
0.4325 = 43.25% probability that the mouse weighs less than 722 grams

Answer:

Step-by-step explanation:
x = 12 − y
2x + 3y = 29
Answers
Bring the variables to one side and the constants to the other side of the equal sign. Remember if you bring anything to the other side it’s sign has to change:
x + y = 12
2x + 3y = 29
Now multiply a variable on the top equation so that it will be equal with the variable on the second:
3x + 3y = 36
2x + 3y = 29
Now subtract the equations which gets you:
x = 7
So we know what the x is, now we have to substitute the x in an equation we created; we’ll go with x + y = 12:
x + y = 12
= 7 + y = 12
Now bring the variable to one side and constants to the other like we did before (remember, the sign must change if the constant or variable is moved to different sides of the equal sign):
y = 12 - 7, which would equal y = 5.
So our answer would be:
( x, y ) = ( 7, 5 )

Answers
Answer:
Below in bold.
Step-by-step explanation:
Density = mass / volume
Mass = 2268 g.
Width of the brick = 28 mm = 2.8 cm.
Volume = 25 * 12 * 2.8 = 840 cm^3
So the density = 2268/840
= 2.7 g/cm^3.
