Calculate the side lengths a and b to two decimal places
Answer:
E
Step-by-step explanation:
using the Sine rule in Δ ABC
\(\frac{a}{sinA}\) = \(\frac{b}{sinB}\) = \(\frac{c}{sinC}\)
where a is the side opposite ∠ A , b opposite ∠ B , c opposite ∠ C
we require to calculate ∠ C
∠ C = 180° - (64 + 85)° = 180° - 149° = 31°
then to find a , using
\(\frac{a}{sinA}\) = \(\frac{c}{sinC}\)
\(\frac{a}{sin64}\) = \(\frac{9.3}{sin31}\) ( cross- multiply )
a × sin31° = 9.3 × sin64° ( divide both sides by sin31° )
a = \(\frac{9.3sin64}{sin31}\) ≈ 16.23 ( to 2 decimal places )
then to find b , using
\(\frac{b}{sinB}\) = \(\frac{c}{sinC}\)
\(\frac{b}{sin85}\) = \(\frac{9.3}{sin31}\) ( cross- multiply )
b × sin31° = 9.3 × sin85° ( divide both sides by sin31° )
b = \(\frac{9.3sin85}{sin31}\) ≈ 17.99 ( to 2 decimal places )
Evaluate the line integral, where C is the given curve. (x 9y) dx x2 dy, C C consists of line segments from (0, 0) to (9, 1) and from (9, 1) to (10, 0)
You have some missing symbols, so I'm guessing that the integral reads
\(\displaystyle \int_C (x-9y) \, dx - x^2 \, dy\)
where C is composed of the two line segments,
• C₁ = {(9t, t) : 0 ≤ t ≤ 1}
• C₂ = {(9 + t, 1 - t) : 0 ≤ t ≤ 1}
The integrals over each path are
\(\displaystyle \int_{C_1} (x-9y) \, dx - x^2 \, dy = \int_0^1 (9t - 9\cdot t) (9 \, dt) - (9t)^2 \, dt\)
\(\displaystyle \cdots = -81 \int_0^1 t^2 \, dt\)
\(\displaystyle \cdots = -\frac{81}3 (1^3 - 0^3) = -27\)
and
\(\displaystyle \int_{C_2} (x-9y) \, dx - x^2 \, dy = \int_0^1 ((9 + t) - 9(1 - t)) \, dt - (9 + t)^2 (-dt)\)
\(\displaystyle \cdots = \int_0^1 (81 + 28t + t^2) \, dt\)
\(\displaystyle \cdots = 81 (1 - 0) + 14 (1^2 - 0^2) + \frac13 (1^3 - 0^3) = \frac{286}3\)
Then the overall line integral has a value of
\(\displaystyle \int_C (x-9y) \, dx - x^2 \, dy = -27 + \frac{286}3 = \boxed{\frac{205}3}\)

Monitors manufactured by TSI Electronics have life spans that have a normal distribution with a standard deviation of 1300 hours and a mean life span of 15,000 hours. If a monitor is selected at random, find the probability that the life span of the monitor will be more than 17,340 hours.
Answer:
0.03593
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 17,340
μ is the population mean = 15,000
σ is the population standard deviation = 1300
z score:
z = 17340 - 15000/1300
z =1.8
Probability value from Z-Table:
P(x<17340) = 0.96407
P(x >17340) = 1 - P(x<17340)
= 1 - 0.96407
= 0.03593
The probability that the life span of the monitor will be more than 17,340 hours is 0.03593
One coin is picked at random. What is the probability of picking a quarter or dime? Round the answerthe nearest hundredth of a percent.
Whenever we have "AND" in a probability question, it means "x" [multiplication].
When we have "OR" in a probability question, it means "+" [addition].
Here, we want Probability of Quarter [P(q)] OR Probability of Dime [P(d)].
So, we will add the individual probabilities.
Now,
Total Coins = 7 + 11 + 8 + 15 = 41
Number of Quarters = 7
Number of Dimes = 11
So, we find individual probabilities:
P(q) = 7/41
and
P(d) = 11/41
Now, we add them up:
\(\begin{gathered} P(q)+P(d)=\frac{7}{41}+\frac{11}{41} \\ =\frac{18}{41} \end{gathered}\)To get percentage, we do the division and multiply by 100.
18 divided by 41 = 0.4390
Multiply by 100:
0.4390 * 100 = 43.90%
If H0 is rejected for an analysis of variance, what can we conclude?
a. We can conclude that all the population means have the same value.
b. We can conclude that at least one of the population proportions has a different value.
c. We can conclude that at least one of the population means has a different value than the other population means.
d. We can conclude that all the population means have different values.
Answer: We can conclude that at least one of the population means has a different value than the other population means.
Step-by-step explanation:
When the null hypothesis is rejected for an analysis of variance, we can then conclude that at least one of the population proportions has a different value.
For one-way analysis of variance, it should be noted that the null hypothesis is rejected when there is sufficient evidence which is used in making the conclusion that not all the means are equal and that there is a different value.

The temperature in a hotel is 21 °C.
The temperature in the hotel is 26,7°C warmer than at the top of the mountain.
The temperature at the top of the mountain is 3.2°C colder than at the bottom of the mountain.
Work out the temperature at the bottom of the mountain.
The temperature at the bottom of the mountain is 50.9 °C.
Let's work through the given information step by step to find the temperature at the bottom of the mountain.
The temperature in the hotel is 21 °C.
The temperature in the hotel is 26.7 °C warmer than at the top of the mountain.
Let's denote the temperature at the top of the mountain as T_top.
So, the temperature in the hotel can be expressed as T_top + 26.7 °C.
The temperature at the top of the mountain is 3.2 °C colder than at the bottom of the mountain.
Let's denote the temperature at the bottom of the mountain as T_bottom.
So, the temperature at the top of the mountain can be expressed as T_bottom - 3.2 °C.
Now, let's combine the information we have:
T_top + 26.7 °C = T_bottom - 3.2 °C
To find the temperature at the bottom of the mountain (T_bottom), we need to isolate it on one side of the equation. Let's do the calculations:
T_bottom = T_top + 26.7 °C + 3.2 °C
T_bottom = T_top + 29.9 °C
Since we know that the temperature in the hotel is 21 °C, we can substitute T_top with 21 °C:
T_bottom = 21 °C + 29.9 °C
T_bottom = 50.9 °C
Therefore, the temperature at the bottom of the mountain is 50.9 °C.

Which is the graph of g(x)=[x+3
The graph of the function g(x) = x + 3 is a straight line that passes through the point (0, 3) on the y-axis and has a slope of 1.
To understand how to plot the graph, let's consider a few points on the line.
We can choose any values for x and calculate the corresponding values for g(x).
Let's start with x = 0.
Substituting this value into the function, we get g(0) = 0 + 3 = 3.
So, the point (0, 3) is on the graph.
Next, let's choose x = 1.
Substituting this value into the function, we get g(1) = 1 + 3 = 4.
This gives us another point on the line, (1, 4).
Similarly, we can choose more values for x and calculate the corresponding values for g(x).
For example, if we let x = -1, we get g(-1) = -1 + 3 = 2, giving us the point (-1, 2).
By connecting these points and extending the line in both directions, we obtain a straight line that represents the graph of g(x) = x + 3.
The line has a positive slope of 1, which means it rises by 1 unit vertically for every 1 unit it moves horizontally.
Overall, the graph of g(x) = x + 3 is a straight line that passes through the point (0, 3) and has a slope of 1.

Given equation:
\(y=-\dfrac{1}{2}x+1\)
Parallel lines have the same slope.
Therefore, the slope of the line parallel to the given equation is:
\(m=-\dfrac{1}{2}\)
Substitute the found slope and given point (-4, -1) into the point-slope formula:
\(\implies y-(-1)=-\dfrac{1}{2}(x-(-4))\)
\(\implies y+1=-\dfrac{1}{2}(x+4)\)
\(\implies y+1=-\dfrac{1}{2}x-2\)
\(\implies y=-\dfrac{1}{2}x-3\)
Therefore, the equation of the line passing through (-4, -1) and parallel to the given equation is:
\(\boxed{y=-\dfrac{1}{2}x-3}\)

2x + 7 = -15
can yall do a step by step explanation pls of how to find x
Answer:
Here's a step-by-step explanation of how to find x in the equation 2x + 7 = -15:
First, we want to isolate the variable (x) on one side of the equation. To do this, we need to get rid of the constant (7) on the same side as x.
To cancel out the 7, we need to subtract 7 from both sides of the equation. This gives us:
2x + 7 - 7 = -15 - 7
Simplifying, we get:
2x = -22
Now we want to isolate x completely, so we need to get rid of the coefficient (2) that's multiplied with x.
To cancel out the 2, we can divide both sides of the equation by 2. This gives us:
2x/2 = -22/2
Simplifying, we get:
x = -11
So the solution to the equation 2x + 7 = -15 is x = -11.
Answer:
-11
Step-by-step explanation:
The key to this is to work backwards
You start with -15, and you know that you're adding 7 to get -15
So you take the 7 out of the equation by subtracting it from -15
-15 - 7 = -22
Now your new equation is:
2x = -22
2 times what equals 22? 11 right?
So 2 times -11 would equal -22
Which means that...
x = -11
