Answer:
An isosceles triangle
Step-by-step explanation:
An isosceles triangle has 2 of the same sides and angles.
Plz give me brainliest.
The given triangle with two angels is 70° and will be the isosceles triangle.
What is the isosceles triangle?
A summation, also abbreviated as a sum, is the consequence of adding two or more numbers or quantities. Usually are always an equivalent number of terms in a summation.
There could be only two terms, and there could be one hundred, thousand. There seem to be summations with an infinite number of representatives.
On another hand, an isosceles triangle is a triangle in which any two sides or angles will be the same.
Hence given that the triangle has
Angle first = 70°
Angle second = 70° since there are two angles same so there will also be two sides equal so it will be an isosceles triangle.

2. Not only is the mean of pairs of clothes purchased is 10, but the population standard deviation is 4.5. When the researcher from problem number 1 calculates a standard deviation for the distribution of sample means for her 2,950, 000 samples, is the standard deviation of sample means likely to be less than, greater than, or equal to 4.5? Explain
Answer:
Less than 4.5
Step-by-step explanation:
Given that :
Mean = 10
Population standard deviation (σ) = 4.5
Sample size (n) = 2950000
The standard deviation of sample means becomes smaller or lesser as the sample size increases according to the central limit theorem. This is because the standard deviation of sample means is obtained by dividing the population standard deviation by the square root of the sample size. Thus is called the standard error.
The standard deviation of sample means is called the standard error ; and is obtained by:
Standard Error = σ/√n
Standard Error = 4.5 / √2950000
Standard Error = 4.5 / 1717.5564
= 0.0026200

Graph the equation y=x^2-8x+7y=x on the accompanying set of axes. You must plot 5 points including the roots and the vertex.
what points do i need to plot on the graph from this equation please hurry brainlest for whoever can help and 20 points
Answer: If you're plotting 1 equation (y=x^2-8x):
(-4,16) Vertex
(0,0) root
(8,0) root
If plotting both (y=x^2-8x) & (7y=x):
(-4,16) Vertex
(0,0) root
(8,0) root
(7,1) point on line
(-7, -1) point on line
Step-by-step explanation:
The vertex of the parabolic equation y = x² - 8x + 7 will be at (4, -9).
Now, Let the point (h, k) be the vertex of the parabola and a be the leading coefficient.
Then the equation of the parabola will be given as,
y = a(x - h)² + k
The equation is given below.
y = x² - 8x + 7
Convert the equation into a vertex form. Then we have
y = x² - 8x + 7
y = x² - 8x + 16 - 16 + 7
y = (x - 4)² - 9
Hence, The vertex of the parabolic equation y = x² - 8x + 7 will be at
(4, -9).
So, The graph is given below.

Your family is driving to the mountains for the weekend You travel 200 kilometers in the first two hours during the next hour you stop for lunch and only travel 25 kilometers. What is your average speed. Can you please use (D=st)
Answer: (D= 87.5 kilometers per hour)
Step-by-step explanation: First, divide 200 by 2, which equals to 100. Next, divide 25 by 2, which is 12.5. Lastly, subtract 100 minus 12.5, which equals 87.5. You should end up with a result of (D= 87.5 kilometers per hour).
The distance Train A travels is represented by d = 80t, where d is the distance in kilometers
and t is the time in hours. The distance Train B travels at various times is shown in the
table. What is the rate of each train? Which train is going faster?
Time (hours) Distance (km)
2
190
4
380
5
475
The rate of Train A is 160|
km per hour.
The rate of Train Bis
km per hour.
Train (select)
is going faster.
Answer:
Train B is going faster than Train A
Step-by-step explanation:
The distance travelled by Train A, d = 80t
The distance travelled by Train B is given as follows;
Time (hours) [tex]{}[/tex] Distance (km)
2 [tex]{}[/tex] 190
4 [tex]{}[/tex] 380
5 [tex]{}[/tex] 475
Therefore, we have that the rate of change of Train B is given as follows;
(475 - 380)/(5 - 4) = 95 km/h
(475 - 190)/(5 - 2) = 95 km/h
The rate of change of Train B = 95 km/h
While the distance covered by Train A per 1 hour, t = 1 is given as follows
Distance covered in 1 hour for Train A, d = 80 × 1 = 80 kilometers
The rate of train A = Distance covered/(Time in which the distance was covered)
The rate of train of change A = 80 km/(1 hour) = 80 km/hour
The rate of train of change A = 80 km/h
Therefore, Train B is going faster than Train A.

Answer:
h<0
Step-by-step explanation:
27h-61h>61h-61h
-34h>0
-34h/-34h>0/-34h
H<0
4. H(17)+H(27)=h(29)
H•17 +h(21)=h(29)
17h+h(21)=h(29)
H17 +h•(21)=h(29)
17h+h(21)=h(29)
combine it
17h+21h=h(29)
38=h(29)
38h=h•29
38h=h29
38h-29h=h29-29h
9H=0
divide both side
9h/9 =0/9
H=0/9 or H=0
