PLEASE HELP
For the right triangles below, find the values of the side lengths b and c.
Round your answers to the nearest tenth.
Answer:
b = 1.7
c = 7.1
Step-by-step explanation:
the triangle with side 'b' is a 30-60-90° Δ where the ratio of sides, respectively, are 1 : [tex]\sqrt{3}[/tex] : 2
to find 'b' we could set up this proportion:
b/3 = 1/[tex]\sqrt{3}[/tex]
cross-multiply:
b[tex]\sqrt{3}[/tex] = 3
b = 3 / [tex]\sqrt{3}[/tex]
if we rationalize the denominator, this becomes (3[tex]\sqrt{3}[/tex])/3 which is [tex]\sqrt{3}[/tex] or 1.7
the other triangle is a 45-45-90°Δ where the ratio of the sides are 1 : 1 : [tex]\sqrt{2}[/tex]
if the legs are 5 then the hypotenuse is 5[tex]\sqrt{2}[/tex] or 7.1
In everyday life, you often face situations that may yield a range of possible outcomes, and you are not certain which outcome will result. By assigning a probability to a possible outcome, you attempt to quantify how likely it is that the possible outcome will occur.
A probability is a number between 0 and ------------that reflects the likelihood of some outcome. According to the classical approach to assigning probability, the probability that an outcome occurs is interpreted as:
A. A proportion of the time that the outcome occurs when the experiment or situation is presented repeatedly under identical conditions
B. A value calculated by dividing the number of ways the outcome of interest can occur by the total number of possible outcomes, assuming each outcome is equally likely
C. A personal measure of the strength of belief that an outcome will occur. Suppose you assign a probability using the classical approach. Then you should interpret that probability using the ___________approach.
Answer:
Probability is a number between 0 and 1 ;
B. A value calculated by dividing the number of ways the outcome of interest can occur by the total number of possible outcomes, assuming each outcome is equally likely
Step-by-step explanation:
Probability of an event lies with a standardized range of between 0 and 1.
According to the classical approach, the chances of all members of a set of observations have an equal chance of occurring, hence, the probability of an event A will be defined as the ratio of number of ways an event on interest can occur to the total possible occurrences when all outcomes have equal chances of occurrence.

Please answer number 9 and here is the translation “ Luis already wrote 5 pages of a science report. He plans to write 1 page every hour. He fills in the missing values in the input and output table.” Thank you also giving brainliest
Answer:
The blanks in order for the bottom row are 8, 9. The blanks for the top row is 6.
Step-by-step explanation:
It is counting by 1's starting at 5 for the bottom row and starting at 0 counting by 1's in the top row.
Answer:
in order from left to right, 8, 9, 6
Step-by-step explanation:
Since he already wrote 5 pages and will write 1 more every hour, the top row (# of hours) + 5 will equal the bottom row (pages written). 3+5=8, 4+5=9, and 6+5=11, so from left to right, it's
8, 9, 6

What is the right answer
Answer:
y=x-4
Step-by-step explanation:
Answer:
y=x-4
Step-by-step explanation:
Because the slope is 1/1 or 1x and the line is on (-4,0)
Note: when the slope is 1/1 keep in mind that slope is rise/run (rise over run) which means that you must always be able to go to the right once then up from the line and always end up back on the line.
Have a wonderful day!

I need to figure out how many solutions does the system of equations below have.
y=6/7x-8 and y=7/9x+10/9
Answer:
The system has one solution.
Step-by-step explanation:
To find the number of solutions of the system, we equal both equations for y.
If we have ax = b, in which both a and b are different of 0, we have one solution.
If both a and b are 0, we have infinite solutions.
If a is 0 and b is not, there are no solutions.
y=6/7x-8 and y=7/9x+10/9
So
[tex]\frac{6x}{7} - 8 = \frac{7x}{9} + \frac{10}{9}[/tex]
[tex]\frac{6x}{7} - \frac{7x}{9} = \frac{10}{9} + 8[/tex]
[tex]\frac{54x - 49x}{63} = \frac{10}{9} + \frac{72}{9}[/tex]
[tex]\frac{5x}{63} = \frac{82}{9}[/tex]
[tex]45x = 63*82[/tex]
Both a and b are different of 0, so the system has one solution.
can someone pls help me w this
Answer:
a = 2
b = 1
c = 1
Step-by-step explanation:
The quadratic equation, 2x² + x + 1 = 0, is expressed in the standard form as ax² + bx + c, where a ≠ 0.
Thus,
a = 2
b = 1 (1 * x = x)
c = 1

Solve x2 + 8x − 3 = 0 using the completing-the-square method.
x = four plus or minus the square root of three
x = negative four plus or minus the square root of three
x = four plus or minus the square root of nineteen
x = negative four plus or minus the square root of nineteen
Answer:
Step-by-step explanation:
x^2+8x-3=0 (move constant to other side by adding 3 to each side)
x^2+8x=3 (halve thr linear coefficient, square it and add to each side, (8/2)^2=16)
x^2+8x+16=3+16 (now the left side is a perfect square)
(x+4)^2=19 (now take the square root of each side)
x+4=+-(19^(1/2)) (finally subtract the constant to isolate x by itself)
x= -4+-(19^(1/2))
x=negative four plus or minus the square root of nineteen
Answer:
D) x = negative four plus or minus the square root of nineteen
