Answers
Answer:
Angle BAF and angle BAC is incorrect.
They overlap: adjacent angles do not overlap.
Answer: Choice B
angle BAF and angle BAC are adjacent
=============================================================
Explanation:
Let's go through each of the answer choices.
Choice A is true since angles BAF and CAF form a right angle (90 degree angle). So we can rule this out.Choice B is false. This is the answer. Adjacent angles must share a common ray or side, which does happen with the two angles in question (both share ray AB); however, note that angle BAF is completely inside angle BAC. We cannot have this overlap, or any overlap at all, when it comes to adjacent angles. Choice C is true. The two angles combine or glue together to form a straight angle, which is 180 degrees. We can rule this answer choice out.4) If the sum of two numbers is 64, and the larger number is 3 less than 3 times the
smaller number. Find the smaller number.
Answers
Answer:
x = 67/4
Step-by-step explanation:
Let x = smaller number and y = bigger number
Then x +y = 64 and y = 3x-3
Plugging y into x+y = 64
x + 3x -3 = 64
4x = 67
x = 67/4

11. Sarah's mom buys a basket that contains 8 bottles of lotion. Half of
the bottles each contain 150 milliliters of lotion. The other bottles
each contain 175 milliliters of lotion.
How many liters of lotion does Sarah's mom buy?
Answers
Answer:
1.3 liters
Step-by-step explanation:
4 x 150 is 600
4 x 175 is 700
700 + 600 = 1300 milliliters
1300 milliliters = 1.3 liters
Answer:
1.3 liters
Step-by-step explanation:
So first off, lets find the amount of milileters of lotion there is.
To do this, take 8, and divide it in half:
8/2 = 4. So we know that 4 bottles of lotion each contain 150 militers of lotion.
We know that the other 4 bottles each contain 175 milileters of lotion.
Next, lets multiply the 150 and 175 by the four bottles:
150x4
=
600
175x4
=
700
Now lets add these two values together, to find the total amount of lotion:
700+600
=
1300
Remember, this problem asked for liters of lotion, not milileters. Lets recall that 1000 milileters are equivelent to 1 liter:
1300/1000
=
1.3
This is your answer!
Hope this helps! :)

Answer:
sin is only positive in 1st and 2nd quadrants
Step-by-step explanation:
As you may know, sine is defined as y-term or value in (x, y). You can go see a unit circle.
Remember that sine is y while cosine is x.
Since sine is y, It'd be a horizontal line. And since it's a horizontal line, it intersects two points in a unit circle.

Assume that 200 babies are born to 200 couples treated with the XSORT method of gender selection that is claimed to make girls more likely. Preliminary results from a test of the XSORT method of gender selection involved 200 couples who gave birth to 115 girls and 85 boys. At significance level of 0.1, test whether the proportion of girl births after the treatment is greater than the 50% that occurs without any treatment (optional: show your work of the hypothesis testing in paper). Answer the next three questions
a. test statistic =
b. p-value =
c. What is your decision?
Answers
Answer:
a) test statistic = 2.12
b) p-value = 0.017
c) we reject the Null hypothesis
Step-by-step explanation:
Given data :
N = 200
girls (x) = 115 , Boys = 85
p = x / n = 115 / 200 = 0.575
significance level ( ∝ ) = 0.1
aim : test whether the proportion of girls births after the treatment is greater than 50% that occurs without any treatment .
A) Determine the test statistic
H0 : p = 0.5
Ha : p > 0.5
to determine the test statistic we will apply the z distribution at ( ∝ ) = 0.1
Z - test statistic = ( 0.575 - 0.5) / [tex]\sqrt{0.5*0.5 / 200}[/tex] = 2.12
b) determine the p-value
The P-value can be determined using the normal standard table
P-value = 1 - p(Z< 2.12 ) = 1 - 0.9830 = 0.017
c) Given that the p value ( 0.017 ) < significance level ( 0.1 )
we will reject the H0 because there is evidence showing that proportion of girls birth is > 50%
