What is the area of this acute isoceles trinagle? It doesnt have a height so I am stumped.
Answers
Answer:
11.8 cm²
Step-by-step explanation:
Cosine rule: a ² = b ² + c ² - 2bc COS A
COS A = (b ² + c ² - a ²) / (2bc)
Area of triangle = ½ ab sin C
name the angle that joins the '3' side to either of the '8' sides. label that angle as A.
now, Cos A = (8² + 3² - 8²) / [(2)(3)(8)]
= 3/16.
A = inverse Cos (3/16)
= 79.193°.
Area of triangle = 1/2 ab Sin C (we'll just use letter A instead of C)
= 1/2 (3)(8) sin (3/16)
= 11.8 cm².
another way you can find it is by this simpler method:
think of one side of 8, the side of 3 and the height that you do not know by using Pythagoras' Theorem for right-angled triangle. (a² + b² = c²). go halfway up the '3' side, then cut across straight to where the '8' sides meet. we now have right-angled triangle. let's call the height you don't know h.
we have 1.5² + h² = 8²
h² = 8² - 1.5²
h² = 61.75
h = √61.75
so area = 1/2 X 1.5 X √61.75
= 11.8 cm²

If a bus traveled 120 miles in 2 hours, what was the average speed of the bus in miles per hour?
Answers
Answer:
60
Step-by-step explanation:
if you divide 120(the total distance traveled) by 2(the hours that it traveled) you get 60.
the answer is 60miles/1 hour or 60mph.
explanation:
so the bus completed 120miles in 2 hours. and they want you to find the speed or miles per hour the bus traveled. all you need to do is divide 120/2= 60 so the answer would be 60 miles per hour or 60mph. you know its right because the ratio of 120:2 shows how much per 2 hours we need to divide to find out how the ratio of miles:1 hours (which is better thought of as mph= miles per each hour) to show how much for 1 you divide both sides of 120:2 by 2. so 120÷2=60 : 2÷2=1 so you found the ratio is 60 miles per hour. 60:1 i hope that helps you guys out and that i didnt confuse you more.

σ1=2.2 σ2=3.0
Required:
a. What is the point estimate of the difference between the two population means?
b. Provide a 90% confidence interval for the difference between the two population means.
c. Provide a 95% confidence interval for the difference between the two population means.
Answers
Answer:
a. 2
b. The 90% confidence interval for the difference between the two population means is (1.02, 2.98).
c. The 95% confidence interval for the difference between the two population means is (0.83, 3.17).
Step-by-step explanation:
Before solving this question, we need to understand the central limit theorem and the subtraction of normal variables.
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean \(\mu\) and standard deviation \(\sigma\), the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \(\mu\) and standard deviation \(s = \frac{\sigma}{\sqrt{n}}\).
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Subtraction between normal variables:
When two normal variables are subtracted, the mean is the difference of the means, while the standard deviation is the square root of the sum of the variances.
Sample 1:
\(\mu_1 = 13.6, s_1 = \frac{2.2}{\sqrt{50}} = 0.3111\)
Sample 2:
\(\mu_2 = 11.6, s_2 = \frac{3}{\sqrt{35}} = 0.5071\)
Distribution of the difference:
\(\mu = \mu_1 - \mu_2 = 13.6 - 11.6 = 2\)
\(s = \sqrt{s_1^2+s_2^2} = \sqrt{0.3111^2+0.5071^2} = 0.595\)
a. What is the point estimate of the difference between the two population means?
Sample difference, so \(\mu = 2\)
b. Provide a 90% confidence interval for the difference between the two population means.
We have that to find our \(\alpha\) level, that is the subtraction of 1 by the confidence interval divided by 2. So:
\(\alpha = \frac{1 - 0.9}{2} = 0.05\)
Now, we have to find z in the Z-table as such z has a p-value of \(1 - \alpha\).
That is z with a pvalue of \(1 - 0.05 = 0.95\), so Z = 1.645.
The margin of error is:
\(M = zs = 1.645(0.595) = 0.98\)
The lower end of the interval is the sample mean subtracted by M. So it is 2 - 0.98 = 1.02
The upper end of the interval is the sample mean added to M. So it is 2 + 0.98 = 2.98
The 90% confidence interval for the difference between the two population means is (1.02, 2.98).
c. Provide a 95% confidence interval for the difference between the two population means.
Following the same logic as b., we have that \(Z = 1.96\). So
\(M = zs = 1.96(0.595) = 1.17\)
The lower end of the interval is the sample mean subtracted by M. So it is 2 - 1.17 = 0.83
The upper end of the interval is the sample mean added to M. So it is 2 + 1.17 = 3.17
The 95% confidence interval for the difference between the two population means is (0.83, 3.17).

A sequence of transformations that maps △DEF to △D′E′F′ is a rotation of 90° counterclockwise about the origin followed by a translation two units right.
What is the sequence of transformations?The sequence of vertices ABC(DEF in this question) is clockwise, as is the sequence of A'B'C'(D'E'F in this question). Thus, an even number of reflections is involved, if any reflections are involved. The offered choices do not include suitable reflections.
The orientation of AB(DE) is toward the right. The orientation of A'B'(D'E') is up, so there must be a rotation of 90° CCW. Rotation of 90° CCW about the origin will leave the figure in a position that is 2 units left of where it is shown. The rotation must be followed by a translation 2 units to the right.
Thus, we conclude that a sequence of transformations that maps △DEF to △D′E′F′ is a rotation of 90° counterclockwise about the origin followed by a translation two units right.

estimate the original volume of the pyramid in fig 15.28 given that it's frustum has a 4 m by 4 m squared top which is 12 m vertically above the square base which is 20 m by 20 m (assume that the original problem was raised to a point . Neglect the volume of the entrance of the right of the photograph)
Answers
Answer:
Step-by-step explanation:
To estimate the original volume of the pyramid in Figure 15.28, we can use the formula for the volume of a frustum of a pyramid. The frustum is the portion of the pyramid between the top and bottom, created by removing the top section.
The formula for the volume of a frustum of a pyramid is:
V = (1/3) * h * (A + sqrt(A * B) + B)
Where:
V = Volume of the frustum
h = Height of the frustum (vertical distance between the top and bottom)
A = Area of the top base
B = Area of the bottom base
Given the dimensions provided, we can calculate the areas of the bases:
Area of the top base (A) = 4 m * 4 m = 16 m²
Area of the bottom base (B) = 20 m * 20 m = 400 m²
The height of the frustum (h) is given as 12 m.
Now we can plug these values into the formula:
V = (1/3) * 12 m * (16 m² + sqrt(16 m² * 400 m²) + 400 m²)
Calculating the square root and simplifying:
V = (1/3) * 12 m * (16 m² + 20 m² + 400 m²)
V = (1/3) * 12 m * (436 m²)
V = 1744 m³
Therefore, the estimated original volume of the pyramid in Figure 15.28 is approximately 1744 cubic meters.

two sets of 5 different numbers that have the same standard deviation but different mean
Answers
The sets of 5 different numbers with same standard deviation but different mean are {2,4,6,8,10} and {20,22,24,26,28}.
The standard deviation is a statistic that describes the degree of volatility or dispersion in a set of numerical values.
Values having a low standard deviation are more likely to be within a narrow range of the mean (also known as the anticipated value) of the collection than values with a high standard deviation.The standard deviation of a random variable, sample, statistical population, data set, or probability distribution is equal to the square root of that variable's variance. It is more algebraically straightforward than the average absolute deviation, but being less reliable in practice. The standard deviation is a useful statistic because, unlike the variance, it is expressed in the same unit as the data.Let us consider two data sets :{2,4,6,8,10} and {20,22,24,26,28}
Now for the first set:{2,4,6,8,10}
Mean = (2+4+6+8+10)÷5 = 30÷5 = 6
Standard deviation = 3.16
Now for the second set:{20,22,24,26,28}
Mean = (22+24+26+28+20)÷5 = 120÷5 = 24
Standard deviation = 3.16
Therefore these two data sets have same standard deviation but different mean.

Answers
Answer: Hi! Read the explanation below:
Brainliest? ANS: 8
Step-by-step explanation:
To find the number of unit cubes in a rectangular prism, you can use the number of 1/2 inch cubes by multiplying it by 8. This is because there are 8 unit cubes in a single 1/2 inch cube.
For example, if a rectangular prism has dimensions of 4 x 2 x 3, and each edge is made up of 2 half-inch cubes, then the total number of 1/2 inch cubes in the rectangular prism would be 4 x 2 + 4 x 2 + 2 x 2 + 2 x 2 + 3 x 2 + 3 x 2 = 32. To find the total number of unit cubes, we can simply multiply the number of 1/2 inch cubes by 8, which gives us a total of 256 unit cubes (32 x 8 = 256).
Therefore, by multiplying the number of 1/2 inch cubes by 8, we can find the total number of unit cubes in a rectangular prism.

Answer:
\(\boxed {\tt y=2x+8}\)
Step-by-step explanation:
If we want to find the equation in slope-intercept form, or y=mx+b (m is the slope and b is the y-intercept), we must isolate y on one side of the equation.
We are given the equation:
\(-2x+y=8\)
-2x is being added to y. Since it is negative, we should add 2x to both sides of the equation.
\(-2x+2x+y=8+2x\)
\(y=8+2x\)
According to the Commutative Property of Addition, we can switch 8 and 2x so it is in the form y=mx+b.
\(y=2x+8\)
The equation is y=2x+8 (the slope, m, is 2 and the y-intercept, b, is 8).
