(D) ASA is not a similarity criterion for two triangles.
What is the similarity criterion for two triangles?If two triangles fit one of the following descriptions, they are similar: Angles in two pairs that are corresponding are equal.
The ratio of three sets of corresponding sides is three.
The comparable angles between two pairs of corresponding sides are equal and proportional.
You can use three triangle-specific theorems to quickly distinguish similar triangles.
There are three theorems that can be used to determine whether two triangles are similar: Angle - Angle (AA), Side - Angle - Side (SAS), and Side - Side - Side (SSS).
The triangles' potential similarity criteria are Angle-Angle-Angle (AAA), Side-Angle-Side (SAS), and Side-Side-Side (SSS).
Angle-side-angle (ASA) is thus a choice from the available possibilities to check the congruence of the triangle rather than its similarity.
Therefore, (D) ASA is not a similarity criterion for two triangles.

(C) x+2=2x-3
(D) 3x-4=2x+7
Answer:
3x-4=2x+7 thus: (D)
x = 11
Step-by-step explanation:
Solve for x:
3 x - 4 = 2 x + 7
Subtract 2 x from both sides:
(3 x - 2 x) - 4 = (2 x - 2 x) + 7
3 x - 2 x = x:
x - 4 = (2 x - 2 x) + 7
2 x - 2 x = 0:
x - 4 = 7
Add 4 to both sides:
x + (4 - 4) = 4 + 7
4 - 4 = 0:
x = 7 + 4
7 + 4 = 11:
Answer: x = 11
___________________________
Solve for x:
4 - 2 (x - 5) = x - 19
-2 (x - 5) = -2 x + 10:
(-2 x + 10) + 4 = x - 19
Add like terms. 4 + 10 = 14:
-2 x + 14 = x - 19
Subtract x from both sides:
(-2 x - x) + 14 = (x - x) - 19
-2 x - x = -3 x:
-3 x + 14 = (x - x) - 19
x - x = 0:
-3 x + 14 = -19
Subtract 14 from both sides:
(14 - 14) - 3 x = -14 - 19
14 - 14 = 0:
-3 x = -14 - 19
-14 - 19 = -33:
-3 x = -33
Divide both sides of -3 x = -33 by -3:
(-3 x)/(-3) = (-33)/(-3)
(-3)/(-3) = 1:
x = (-33)/(-3)
The gcd of -33 and -3 is -3, so (-33)/(-3) = (-3×11)/(-3×1) = (-3)/(-3)×11 = 11:
Answer: x = 11
Answer:3x-4=2x+7

A. 2x+10=8
2x= -18

What is the equation of the line that passes through the point (-1,2) and has a slope of -1?
The equation of the line that passes through the point (-1,2) and has a slope of -1, in point-slope form is: y - 2 = -1(x + 1).
What is the Equation of a Line?If we know one point (a, b), that a line passes through and its slope (m), we can write the equation of that line in point-slope form as y - b = m(x - a).
Given the following:
A point (a, b) = (-1, 2)
The slope of the line (m) = -1
To write the equation of the line, substitute m = -1, a = -1, and b = 2 into y - b = m(x - a):
y - 2 = -1(x - (-1))
y - 2 = -1(x + 1).
The answer is: y - 2 = -1(x + 1).

Using the z-distribution, it is found that the 95% confidence interval for the mean lifetime of this type of drill, in holes drilled, is (10.4, 13.94).
We are given the standard deviation for the population, hence, the z-distribution is used. The parameters for the interval is:
Sample mean of [tex]x = 12.7[/tex]
Population standard deviation of [tex]\sigma = 6.37[/tex]
Sample size of .n = 50
The margin of error is:
[tex]M = z \frac{\sigma }{\sqrt{n} }[/tex]
In which z is the critical value.
We have to find the critical value, which is z with a p-value of [tex]\frac{1+\alpha }{2}[/tex] , in which [tex]\alpha[/tex] is the confidence level.
In this problem, , thus, z with a p-value of , which means that it is z = 1.96.

Store B is offering the best unit rate for bananas.
What is Rate?
A rate in arithmetic is a ratio that contrasts two separate values with various unit systems. For instance, if John types 50 words per minute, that means he types 50 words per minute. We are dealing with a rate because the word "per" is there. The symbol "/" can be used in place of the word "per" in issues.
When two or more similar amounts or numbers are being compared using the same units, a ratio is utilized. When referring to the ratio of one quantity "to" the second quantity in spoken language, it is frequently written with a colon.
Grocery Store A is selling bananas for $0.75 for 12 pounds.

What is the equation of the line that passes through the point (-3,-3)(−3,−3) and has a slope of 33?
The required equation of the line having a slope of 33 and passing through (-3, - 3) is y = 33x + 96.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Let the required line be y = mx + b.
∴ - 3 = (33)(-3) + b.
- 3 = - 99 + b.
b = 96.

A cylindrical wooden column is 3 m high and 28 cm in diameter use value π to calculate the mass in kf of the column if the density of the wood is 0.8g/cm^3
Answer:
1.478 kg
Step-by-step explanation:
Considering density=mass/volume, when we rearrange, we get mass=density*volume. Therefore, as we are given the density, we just need to find the volume to know the mass. The volume of a cylinder is πhr^2, and our radius is 28/2=14, so the volume of the cylinder is π*3*14^2=588π. Then, 588π*0.8=470.4π which is about 1477.8052 g. Then, to convert to kg, we can divide this by 1000 and get about 1.478 kg.

O ll only
O IIl only
O I only
O all three distributions
O II and III
II and III only distributions has a mean that varies
The mean of a distribution is a measure of the central tendency of the data, and it can vary depending on the sample being analyzed.
For the population distribution, the mean is a fixed value that is calculated using all of the data in the population. The mean of the population distribution does not vary.
For the distribution of sample data, the mean is calculated using the data in the sample. If you take different samples from the same population, the mean of each sample will be different, so the mean of the distribution of sample data varies.
For the sampling distribution of the sample mean, the mean is calculated using the means of multiple samples. The mean of the sampling distribution is known as the population mean. As with the distribution of sample data, the mean of the sampling distribution varies depending on the samples that are used to calculate it.
Therefore, the mean of the distribution of sample data and the sampling distribution of the sample mean both vary, while the mean of the population distribution does not vary.

the edison electric institute has published figures on the number of kilowatt hours used annually by various home appliances. it is claimed that a vacuum cleaner uses an average of $46$ kilowatt hours per year. if a random sample of $12$ homes included in a planned study indicates that vacuum cleaners use an average of $42$ kilowatt hours per year with a standard deviation of $11.9$ kilowatt hours, do these data suggest that at the $0.05$ significance level the mean annual usage of vacuum cleaners is less than $46$ kilowatt hours? assume the population distribution of usage in kilowatt hours to be normal.
The test statistic is less than - 1.796
Hypothesisi test
H0: μ = 46
Ha: μ < 46
This is a lower tailed test
mean = 42
standard deviation = 11.9
sample size n = 12
The level of significance α = 0.05
degree of freedom df = n - 1 = 12 - 1 = 11
Test statistic = (x - mean)/(standard deviation / √n) = (42 - 46)/(11.9 / √12) = - 1.164
Test statistic = - 1.164
Using t- table, we can observe that the p - value is between 0.10 and 0.15
Using excel we find p - value = P(t < - 1.796)
p value = 0.1344
H0: μ < 46, rejection rule is
Reject H0 if test statistic < - 1. 796
Therefore, we reject the hypothesis as the test statistic is less than - 1.796

suppose that an experimenter studies the lifespan of members of a colony of bacteria. let t be the lifespan of a randomly chosen member of the colony. suppose the lifespan of the bacteria has an exponential distribution with expected value 100 minutes. if we choose 5 members of the colony, what is the probability that at least one of them lives more than 87 minutes?
The probability that at least one of them lives more than 87 minutes is 0.87.
Probability
In statistics, the possible way of happening a particular event is called probability.
Given,
Suppose that an experimenter studies the lifespan of members of a colony of bacteria. let t be the lifespan of a randomly chosen member of the colony. suppose the lifespan of the bacteria has an exponential distribution with expected value 100 minutes.
Here we need to find if we choose 5 members of the colony, then what is the probability that at least one of them lives more than 87 minutes.
Here we know that,
Total number of members = 5
Life span = 87 minutes
Expected value = 100 minutes
So, the probability is calculated as,
=> 87 /100
=> 0.87

Which of the following pairs of equations has exactly the same solution?(1 point)
−3.2x=0.64 and x/4 =−0.05
⅜ x=1 and ⅓ x=⅛
x/3.2 =1.8 and 1.8x=3.2
− 3/4 x=5/2 and 5/2 x=− 3/4
Answer: The first pair of equations, i.e., −3.2x=0.64 and x/4 =−0.05, have exactly the same solution. In both of these equations, the value of x comes out as -0.2.
Step-by-step explanation: Simplifying the first set of equations, we get:[tex]-3.2x=0.64[/tex]
[tex]x=0.64/-3.2[/tex]
x=-0.2
[tex]x/4=-0.05[/tex]
[tex]x=-0.05*4[/tex]
x=-0.2
Simplifying the second set of equations, we get:
[tex]3/8x=1[/tex]
[tex]x=8/3[/tex]
x=2.66
[tex]1/3x=1/8[/tex]
[tex]x=1/8*3[/tex]
x=0.375
Simplifying the third set of equations, we get:
[tex]x/3.2=1.8[/tex]
[tex]x=1.8*3.2[/tex]
x=5.76
[tex]1.8x=3.2[/tex]
[tex]x=3.2/1.8[/tex]
x=1.77
Simplifying the fourth set of equations, we get:
[tex]-3/4x=5/2[/tex]
[tex]x=5/2*-4/3[/tex]
x=-3.33
[tex]5/2x=-3/4[/tex]
[tex]x=-3/4*2/5[/tex]
x=-0.3
Therefore, the first pair of equations, i.e., −3.2x=0.64 and x/4 =−0.05 have exactly the same solution.
