Solve the triangle for x.
(View the attachment)
A. 39.4(degrees)
B. 46.5(degrees)
C. 94.1(degrees)
D. 105.9(degrees)
Answer:
Option C
Step-by-step explanation:
By applying cosine rule in the given triangle,
BC² = AB² + AC² - 2(AB)(AC)cosA
(11)² = 8² + 7² - 2(8)(7)cosx
121 = 64 + 49 - 112cos(x)
cos(x) = -[tex]\frac{8}{112}[/tex]
x = [tex]\text{cos}^{-1}(-\frac{1}{14})[/tex]
x = 94.1°
Therefore, Option C will be the correct option.

how do you write an equation in slope-intercept form for the line with a slope 5 and y-intercept -5
Answer:
y=5x-5.
Step-by-step explanation:
slope-intercept form of a line is y = mx+b, where m is the slope and b is the y intercept. Simply plug in the numbers you get.
Thus, we get y = 5x-5.
A new reading program may reduce the number of elementary school students who read below grade level. The company that developed this program supplied materials and teacher training for a large-scale test involving nearly 8500 children in several different school districts. Statistical analysis of the results showed that the percentage of students who did not meet the grade-level goal was reduced from 15.9% to 15.1%. The hypothesis that the new reading program produced no improvement was rejected with a P-value of 0.023.
a) Explain what the P-value means in this context.
b) Even though this reading method has been shown to be significantly better, why might you not recommend that your local school adopt it?
Answer:
The solution to the given points can be defined as follows:
Step-by-step explanation:
In point a:
There is still a 2.3% chance which 15.1% of learners who also don't achieve a level by naturally-excluding specimens only will see if 15.9% is the population means value.
In point b:
Throughout the old system, 1352 learners must not read in classes, but 1284 should not write throughout academic performance throughout the new curriculum. A reduction, as well as the significance of such a decrease, would depend mostly on the cost of switching to the new initiative.
a. The explanation of the p-value should be explained below.
b. The suggestion that should not be considered is also explained below.
P-value and the suggestion not considered:a. Since there is a still 2.3% chance that 15.1% of learners should not accomplish the level via naturally-excluding specimens only would watch in the case when 15.9% should represent the mean value of the population.
b. If we considered the old system, so 1352 learners should not read the class however, 1284 should not write the academic performance. So there is the reduction that based on the switching cost

______
A. 710
B. 1,358
C. 720
D. 1,368
Answer:
D
Step-by-step explanation:
First, start with the ones column. 2*9 is 18, so write the 8 below and carry the 1 into the tens column. Now, we do 9*7 plus the 1 we carried, so that makes 64. The first row under the line should be 648. Next, annex a zero under the number 648 in the ones column. Now we move to the tens. 1*2 is 2. 1*7 is 7. The number under 648 should be 720. Now, we add 648 and 720. 648+720 is 1,368. 1,368 is our final product, which makes the answer D. I'm sorry if this seemed confusing (it's a bit hard to explain in words), but I hope it helps!
Americans eat an average of 100 acres of pizza per year. That is equivalent to 4,356,000 square feet of pizza per year. How is the area expressed using scientific notation?
Answer:
D. [tex] 4.356 * 10^6 [/tex] ft²
Step-by-step explanation:
Scientific notation of a number is expressed in the following form, [tex] a * 10^b [/tex]
Where,
a = decimal number (1 ≤ |a| < 10)
b = the power of 10 whereby the scientific notation is equivalent to the original number.
To express 4,356,000 square feet in scientific notation, do the following:
1. Move the decimal point to the left up to the last non-zero digit = a = 4.356
2. Since we moved the decimal point by 6 decimal places, therefore, b = 6
3. Substitute the values of the variables into
Thus:
4,356,000 = 3. Substitute the values of the variables into
a * 10^b
Thus:
4,356,000 = 4.356 * 10^6

How do you round to the nearest unit?
Help me here plz thanks
Answer:
Rounding to the nearest unit means to find the nearest integer to a given number. Before you remove the decimal take the first number of the decimal (45.68) Take 6 (The number that comes first after the decimal).
If the number is 5 and less then convert the number to a lower number.
If the number is more than 5 then convert the number to a higher number.
Ex: 34.41. The answer would be 33 because 4 is less than 5.
Ex: 34.61. The answer would be 35 because 6 is more than 5.
I hope this helps :)
Answer:
Bonjour CocinelleStep-by-step explanation:
Rounding to the nearest unit means to find the nearest integer to a given number.
Basically, you have to get rid of the decimal part, if any.
As an immediate corollary, you have that if a number x
is already an integer, then there's no point in rounding it, since the result would be x itself.
Now, let's assume that our number actually has a decimal part, for example
4.687
It might help you to think of this number as
4+0.687
to clearly see that 4.687 lies between
4 and 5
, since it is something (0.687) more than 4 , but still not 5
So, the question is: is our number closer to
4 or to 5? Which, in turn, means to ask: the decimal part that we've added,
0.687 , is nearest to 0 or 1 ?
If it is nearest to 0 , it means that our number is more than 4 , but still nearer to
4
than it is to 5, otherwise it is "far enough" from 4 to be nearer to 5
Since halfway between 0 and 1 is 0.5 , and our decimal part is 0.687>0.5 , we can say that 4.687 is rounded to
5.

What is the Anser right answer gets brainliest
Answer:
c>5
Step-by-step explanation:
Answer:
c>5
Step-by-step explanation:
First, you have to convert the 8 9/12 into an improper fraction(which would make 8 91/2 into 105/12). Then you reduce 105/12 into its simplest form which is 35/4. Now you need to subtract 1.25 from the left and move -1.25 to the right. Your inequality should look like this. 1.5c>35/4-1.25. Next, you need to convert -1.25 into a fraction, which would make it -5/4. Calculate the difference between 35/4 and -5/4. Your answer should be 15/2. The inequality now looks like this; 1.5c>15/2. Now to get rid of the 1.5 you have to divide both sides by 1.5. By doing this you should get c>5.
