Answer: The correct option is the first one.
Step-by-step explanation:
Let's define how to interpret each symbol:
x < a (x is strictly smaller than a, we graph this with an open circle at a, and an arrow to the left of a)
x > a (x is strictly larger than a, we graph this with an open circle at a, and an arrow to the right of a)
x ≥ a (x is larger than or equal to a, we graph this with a closed circle at a, and an arrow to the right of a)
x ≤ a (x is smaller than or equal to a, we graph this with a closed circle at a, and an arrow to the left of a)
In this case, we have the inequality:
x ≤ 15
Then to graph this we need a closed circle at 15, and an arrow to the left. The correct option is the first one.

A medical supplier sells gauze in large and small rectangular sheets. A large sheet has a length of 9 inches and an area of 45 square inches. A small sheet has a length of 4 inches and a width of 3 inches. Are the sheets similar?
Answers
Answer:
Step-by-step explanation:
Large sheet:
Length = 9 inches
Width of large sheet = area ÷ length = 5 inches
ratio of length to width = 9:5
Small sheet:
Length = 4 inches
Width = 3 inches
ratio of length to width = 4:3
9:5 ≠ 4:3
The sheets are not similar
The large sheet and small sheet are not similar because they have different dimensions.
What is the area of a rectangle ?
Area of rectangle is the region occupied by a rectangle within its four sides or boundaries.
It is given that large sheet has a length of 9 inches and an area of 45 square inches whereas the small sheet has length of 4 inches and a width of 3 inches.
Let's find out the area of small sheet which will be :
A = L × B
A = 4 × 3
A = 12 inches²
Whereas , in case of large sheet the area is 45 inches². So , the area of both sheets are not similar.
Let's check if dimensions are same.
Width of large sheet will be :
A = L × B
45 = 9 × B
or
B = 5 inches
So , dimensions are also not equal.
Therefore , the large sheet and small sheet are not similar because they have different dimensions.

The cost to produce a batch of granola bars is approximately Normally distributed with a mean of $7.19 and a standard deviation of $0.86. If a random sample of 12 batches of granola bars is selected, what is the probability that the mean cost will be more than $7.00?
0.2220
0.2339
0.7653
0.7780
Answers
Answer:
0.7780
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal probability distribution
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.
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.
Population:
We have that [tex]\mu = 7.19, \sigma = 0.86[/tex]
Sample of 12:
[tex]n = 12, s = \frac{0.86}{\sqrt{12}} = 0.2483[/tex]
What is the probability that the mean cost will be more than $7.00?
This is 1 subtracted by the pvalue of Z when X = 7. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{7 - 7.19}{0.2483}[/tex]
[tex]Z = -0.765[/tex]
[tex]Z = -0.765[/tex] has a pvalue of 0.222
1 - 0.222 = 0.778
So the answer is 0.7780

2x+3=11?
Answers
Answer:
2x+3=11
2x=11-3
x=8/2
x=4........
Answer: [tex]x = 4[/tex]
Step-by-step explanation:
Okay, so we start with our equation.
[tex]2x + 3 = 11[/tex].
Then we need to get x alone. To do that we subtract the 3 on the side with the x.
But what we do to one side, we do to the other. So we subtract 3 from the 11 as well
2x + 3 = 11
-3 -3
2x = 8
Then we divide by 2 on both sides to get X.
[tex]\frac{2x}{2} =\frac{8}{2}[/tex]
[tex]\frac{2x}{2} = x[/tex]
[tex]\frac{8}{2} = 4[/tex]
[tex]x = 4[/tex].

10 ways to divide 96 into equal groups

6+6+6+6+6+6+6+6+6+6+6+6+6+6+6+6=96
I'm not going to write out the rest of the numbers. I'll multiply them.
4 x 24=96 (etc. 4+4+4....)

1 x 96=96 (etc. 1+1+1....)
I hope this is what you meant. If you liked, mark me Brainliest please.
The number 96 is divided into equal groups, then the number of 10 ways is shown below.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
48 + 48 = 96
32 + 32 + 32 = 96
24 + 24 + 24 + 24 = 96
12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 = 96
6 + 6 + 6 + 6 + 6 + 6 + 6 + 6 + 6 + 6 + 6 + 6 + 6 + 6 + 6 + 6 = 96
And the rest are written in the form of multiplication. Then we have
4 x 24 = 96 (etc. 4 + 4 + 4 ....)
3 x 32 = 96 (etc. 3 + 3 + 3 ....)
2 x 48 = 96 (etc. 2 + 2 + 2 ....)
1 x 96 = 96 (etc. 1 + 1 + 1 ....)

The ratio of the measures of the sides of a triangle is 2:8:9. If the perimeter of the triangleis 76 inches, find the length of each side. for geometry
Answers
Answer:
The lenghts of the sides are: 8 inches, 32 inches, 36 inches.
Step-by-step explanation:
Perimeter of a triangle:
The perimeter of a triangle is given by the sum of it's sides dimensions.
The ratio of the measures of the sides of a triangle is 2:8:9.
This means that their measures are:
The first measure is x
The second measure is of: [tex]\frac{8x}{2} = 4x[/tex]
The third measure is of [tex]\frac{9x}{2}[/tex]
So the perimeter will be of:
[tex]x + 4x + \frac{9x}{2} = 76[/tex]
[tex]5x + \frac{9x}{2} = 76[/tex]
[tex]\frac{10x}{2} + \frac{9x}{2} = 76[/tex]
[tex]\frac{19x}{2} = 76[/tex]
[tex]19x = 76*2[/tex]
Simplifying by 19
[tex]x = 4*2 = 8[/tex].
So, dimensions of:
[tex]8, 4*8 = 32, \frac{9*8}{2} = 36[/tex]
The lenghts of the sides are: 8 inches, 32 inches, 36 inches.
