PLEASE HELP IM IN MY FINALS I WILL GIVE BRANLIEST Find the slope of the line through each pair of points. (-8, 15),(-1,9)
There were 3 chihuahuas at the dog park last Saturday, along with 9 other dogs. Considering this data, how many of the next 20 dogs to arrive at the park next Saturday should you expect to be chihuahuas?
Answer:
5
Step-by-step explanation:
Since there are 3 chihuahuas out of 12 dogs IN TOTAL (which includes the 9 other dogs), the ratio is 1:4, or 1/4.
Assuming this ratio is consistent, (1/4)*20 is 5.
In conclusion, you can expect there to be 5 chihuahuas out of the next 20 dogs to arrive at the park.

Answer:
[tex]\huge\boxed{\sf h = 26.684\ feet}[/tex]
Step-by-step explanation:
See the attached file along with the solution.
Let the height be h,
base of triangle 1 be x
base of triangle 2 be 100 - x
Using the following trigonometry for both the triangles.
[tex]\displaystyle tan (\theta) = \frac{opposite}{adjacent}[/tex]
For triangle 1:
tan 20 = h / x ---------------------(1)
For triangle 2:
tan 45 = h / 100 - x -----------------(2)
Taking Eq. (1)
tan 20 = h / x
Multiply both sides by x
tan 20 * x = h
h = tan (20) * x
h = 0.36397x -----------------------(3)
Put Eq. (3) in (2)
tan (45) = 0.36397x / 100-x
1 = 0.36397 x / 100 - x
Multiply both sides by 100 - x
100 - x = 0.36397 x
Add x to both sides
100 = 0.36397 x + x
100 = 1.36397 x
Divide both sides by 1.36397
100 / 1.36397 = x
73.315 = x
x = 73.315 feet
Now, Finding h (height):
tan 20 = h / x (Eq. (1))
h = tan (20) * x
h = 0.36397 * 73.315
h = 26.684 feet

What is law of cosine ?The square of a side of a plane triangle equals the sum of the squares of the remaining sides minus twice the product of those sides and the cosine of the angle between them.
c² = a² + b² - 2ab cos[tex]\rm \gamma[/tex]
Here in triangle EFG ,
To find angle G
a = 12
b=10
c=8
8² = 12² + 10² - 2*12*10 cos[tex]\rm \gamma[/tex]
64 = 144 + 100 -240 cos [tex]\rm \gamma[/tex]
64-244 = -240 cos[tex]\rm \gamma[/tex]

Answer: 352
Step-by-step explanation:
IQ: Scores on a certain IQ test are known to have a mean of 100. A random sample of 60 students attend a series of coaching classes before taking the test. Let μ be the population mean IQ score that would occur if every student took the coaching classes. The classes are successful if μ > 100. A test is made of the hypotheses H0: μ = 100 versus H1: μ > 100. Consider three possible conclusions: (i) The classes are successful. (ii) The classes are not successful. (iii) The classes might not be successful.
a. Which of the three conclusions is best if H0 is rejected?
b. Which of the three conclusions is best if H0 is not rejected?
c. Assume that the classes are successful but the conclusion is reached that the classes might not be successful. Which type of error is this?
d. Assume that the classes are not successful. Is it possible to make a Type I error? Explain.
e. Assume that the classes are not successful. Is it possible to make a Type II error? Explain.
Answer:
a.) The classes are successful
b.) The classes might not be successful.
c.) Type 11 error
d.) Yes
E.) No
Step-by-step explanation:
C.)
This means that we failed to reject H0 when it is actually FALSE and in fact the classes are successful , that means mean μ > 100, that is: null hypothesis is False.
D.)
Type 1 error occurs when we incorrectly reject H0 ; that is we rejected H0, when it is true
Here, H0, means the classes aren't successful, hence, incorrectly rejecting H0 means we have committed a type 1 error
E.)
Type 11 error means failing to reject H0
;
Here, H0, means the classes aren't successful,
Hence, if we fail to reject H0 in this scenario, we are right, hence, there is no possibility of making a type 11 error in this scenario

He records this data for an entire year by keeping track of his customers' purchases.
His customer's purchases will be from his shop and no one elses from the neighbours or of other company.
The only way to keep record of his customers' purchases is from his shop.
Option a is incorrect because he wants to check the drive force of his shop not other shops.
Option b is also incorrect because the items bought indicate the purchases not the preference told.
Option d is also incorrect becuase nearby companies wil have their own styles and sizes collection.

What is the value of x in the solution to this system of equations?
5x+2y=67x=3y−7
Question 4 options:
6
18.5
24
11
Answer:
x = 11
Step-by-step explanation:
Given the expression;
5x+2y=67 ...1
x=3y−7 ....2
Substitute 2 into 1
5(3y-7)+2y = 67
15y - 35 + 2y = 67
17y = 67+35
17y = 102
y = 102/17
y =6
Recall that x = 3y - 7
x = 3(6) - 7
x = 18 - 7
x = 11
Hence the value of x is 11
