30 degrees
The required measure of ∠RST is 100° for the given triangle.
What is a Triangle?Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles. It is one of the fundamental shapes in geometry and is represented by the symbol Δ.
As per the given figure, we have
∠SRT = 40° and ∠STR = 40°
We have to determine the measure of ∠RST
In triangle SRT,
Since the angle of sum property asserts that the sum of all triangle's angles is 180°.
So, ∠SRT + ∠RTS + ∠RST = 180°
40° + 40° + ∠RST = 180°
80° + ∠RST = 180°
Subtract 80 from both sides of the above equation,
∠RST = 180° - 80° = 100°
Therefore, the required measure of ∠RST is 100°

what is the exact decimal equivalent of 7/10
Answer:
Step-by-step explanation:
Decimals are out of 100.
7/10 = 70/100
Which equals to 0.70 or 0.7
So your answer is 0.70 (0.7)
Answer:
The exact decimal equivalent of 7/10 is 0.7
Step-by-step explanation:
The reason for this is because when you divide something by ten you move the decimal place one place to the left.
So then 7.0 becomes 0.7 because the decimal place is moved once divided by ten.

Answer:
The length of \(\overline{JO}\) is 48.
Step-by-step explanation:
A square is a quadrilateral whose four sides have the same length and four internal angles have the same measure. The sum of measures of internal angles in quadrilaterals equals 360°. Let \(m\,\angle BOJ = 4\cdot x -6\) and \(BO = 2\cdot x - 8\), the value of \(x\) is:
\(4\cdot (4\cdot x - 6) = 360^{\circ}\)
\(16\cdot x -24 = 360^{\circ}\)
\(16\cdot x = 384^{\circ}\)
\(x = 24\)
And the length of \(JO\) is:
\(JO = BO = 2\cdot x - 8\)
\(JO = 40\)
The length of \(\overline{JO}\) is 48.

PLEASE HELP!!!!! 2.) What is the perimeter of a polygon with vertices at (-3, 1), (5, 1), (-3, 4), (5, 4)? 30 points if you can help
Answer:
22 units.
Step-by-step explanation:
We want to find the perimeter of the polygon with vertices at: (-3, 1); (5, 1); (-3, 4); and (5, 4).
Let’s first plot the points and see what polygon we acquire. Please refer to the graph below.
As we can see, when plotting the points and connecting them, we get a rectangle.
So, we can use the perimeter formula for a rectangle, given by:
\(P=2(\ell+w)\)
Where \(\ell\) Is the length and \(w\) is width.
Remember that the perimeter is simply the distance around the figure.
So, let’s find the length. We can do so by counting or by subtracting.
By counting, we can see that the length (longer side) is 8 units.
And by subtracting, we get the same length of |5-(-3)| or 8 units.
We use absolute value because distance is always positive.
Using the same process, we find the width to be 3 units.
Using subtract, we can see that this is indeed true as |1-4|=3.
So, we can now substitute the values into our formula:
\(P=2(8+3)\)
Evaluate:
\(P=2(8+3)=2(11)=22\text{ units}\)
So, the perimeter of the polygon is 22 units.

alfred and bonnie play a game in which they take turns tossing a fair coin. the winner of a game is the first person to obtain a head. alfred and bonnie play this game several times with the stipulation that the loser of a game goes first in the next game. suppose that alfred goes first in the first game, and that the probability that he wins the sixth game is m n , where m and n are relatively prime positive integers. what are the last three digits of m n ? (1993,
So, the last three digits of m*n is 001.
Let p be the probability that Alfred wins given that he goes first. Then, the probability that Bonnie wins given that she goes first is 1-p. Therefore, the probability that Alfred wins the second game given that Bonnie went first in the first game is 1-p. Similarly, the probability that Alfred wins the third game given that he went first in the second game is p, and so on.
Therefore, the probability that Alfred wins the sixth game given that he went first in the first game is:
p(1-p)(1-p)(p)(p)(p) = p^4 (1-p)^2
Since m and n are relatively prime, the last three digits of m*n are the last three digits of p^4 * (1-p)^2, which is the last three digits of p^4 and the last three digits of (1-p)^2. Since p is the probability of winning given that you go first, it is a number between 0 and 1. Therefore, the last three digits of p^4 and (1-p)^2 are 001, resulting in the last three digits of the final answer being 001.
Therefore, the last three digits of m*n is 001.

Write the equation of the line that passes through the points (- 9, - 9) and (- 8, 1) Put your answer in fully simplified point-slope form, unless it is a vertical or horizontal line
The point-slope form of the line equation that passes through the points (- 9, - 9) and (- 8, 1) is equals to the y= 10x + 81.
The standard equation of a line is, y = mx + b where m is the slope and b is the y-intercept. This is a very useful form of the linear equation when comparing lines. We have to determine the equation of the line that passes through the points (- 9, - 9) and (- 8, 1). First we determine the value of slope of line. The formula for slope of line that passing through the points (x₁,y₁),(x₂,y₂) is \(m = \frac{y_2 - y_1}{x_2- x_1} \)
here, x₁ = -9, y₁ = -9 , x₂ = -8, y₂ = 1, so
\(m = \frac{1-(-9)}{-8-(-9)} = \frac{10}{1} = 10\)
The point-slope form for line passing through points (x₁,y₁),(x₂,y₂) is y − y₁ = m(x − x₁)
=> y - (-9) = 10( x -(-9))
=> y + 9 = 10( x + 9)
=> y + 9 = 10x + 90
=> y = 10x + 81
Hence required equation is y = 10x + 81.

What is the triangle?A triangle is a three-sided polygon with three angles. It is a fundamental geometric shape and is often used in geometry and trigonometry.
Since triangles P and Q are similar, their corresponding sides are proportional. That means:
AP/PN = BX/QN
We know that AP = 7cm and PN = 9cm, so we can substitute those values:
7/9 = BX/QN
We also know that QC = 6cm, so we can find QN by subtracting CN from QC:
QN = QC - CN
QN = 18cm - 6cm
QN = 12cm
Now we can solve for BX:
7/9 = BX/12
Multiplying both sides by 12, we get:
BX = 84/9
Simplifying, we get:
BX = 28/3 cm
Therefore, the lengths of the sides are:
AP = 7cm
BC = 6cm
BX = 28/3 cm
QN = 12cm

a random number generator picks a number from one to nine in a uniform manner. find mu
The expected value or mean μ of the random number generator is 5.
To find μ, the expected value or mean of the random number generator that picks a number uniformly from one to nine, we can use the formula for the mean of a discrete uniform distribution.
In a discrete uniform distribution, all outcomes have equal probabilities. Since the random number generator picks a number from one to nine uniformly, each number has a probability of 1/9.
The formula for the mean of a discrete uniform distribution is:
μ = (a + b) / 2
where a is the minimum value and b is the maximum value of the distribution.
In this case, a = 1 and b = 9. Substituting these values into the formula, we have:
μ = (1 + 9) / 2
= 10 / 2
= 5.
Therefore, the expected value or mean μ of the random number generator is 5.

Which option below demonstrates the correct notation for a continuous set of all numbers between 5 and 6, not including 5, but including 6?
Answer:
The set is (5, 6]
Step-by-step explanation:
Ok, let's see the different possibles notations to describe sets.
If we want to describe a discrete set, we use {}
Like in the set:
{1, 2, 3}
That set only contains the numbers 1, 2, and 3.
If we want to describe a continuous set that does not include the extremes, we use ()
For example:
(1, 3)
Contains all the numbers between 1 and 3, but does not include 1 and 3.
If we want to include the extremes, we need to use []
[1, 3]
This set is all the numbers between 1 and 3, including the values 1 and 3.
And we can mix these last two notations, so if we want a set that includes all the numbers between 5 and 6, not including 5 but including 6, we need to write:

Answer:
Step-by-step explanation:
If they want the average for four months to be 55 minutes, this means that the total of the four months = 55 x 4
Total of four months = 220 minutes
They already told us that the three previous months she used her cellphone for 43 minutes, 62 minutes and 57 minutes.
All you have to do now is subtract everything from the total of the four months.
4th month = 220 - 43 - 62 - 57

If x is a normal N(4,64) distribution, find P(X ≤ –5.2)
X is a normal distribution with mean 4 and standard deviation 8 (since the variance is 64), therefore P(X ≤ –5.2) is approximately 0.1251.
If X follows a normal distribution N(4,64), then it has a mean (μ) of 4 and a variance (σ²) of 64, with a standard deviation (σ) of 8. To find the probability P(X ≤ -5.2), we need to calculate the z-score for -5.2 and use the standard normal distribution table.
Substituting in the values, we get:
z = (-5.2 - 4) / 8
z = -1.15
Now, we can look up the probability of a standard normal distribution with a z-score of -1.15 using a table or calculator, which gives us:
P(Z ≤ -1.15) = 0.1251
Therefore, P(X ≤ –5.2) is approximately 0.1251.

The standard deviation of the mean birth weights for samples of 100 babies is 50 grams.
The standard deviation of the mean birth weights for samples of 100 babies can be calculated using the formula:
Standard deviation of the mean = Standard deviation of the population / sqrt(sample size)
Given that the standard deviation of birth weights for individual babies in the population is 500 grams, and the sample size is 100, we can plug in these values into the formula:
Standard deviation of the mean = 500 / sqrt(100) = 50 grams
