Answer:
19.8 cm
Step-by-step explanation:
Using the Pythagorean theorem , the Square of the distance between the top of the piece and the Shadow Is the sum of the height of the piece. and the lenght of the shadow. basically Just build a triangle with the 3 points you are given: height of the piece, lenght of the shadow and distance between the 2. so it's sqrt(13^2+15^2) = sqrt(394) =19.8 cm

Answer:
P(Red) = 0.44
Step-by-step explanation:
There are 3 (mutually exclusive) ways to get red. The probability of red is the sum of the probabilities of the different ways to get there:
P(red) = (0.35)(0.6) + (0.45)(0.2) + (0.20)(0.7) = 0.21 + 0.09 + 0.14 = 0.44
The probability a player will select a red ball is 0.44.

Step-by-step explanation:
The table shows the number of practice problems completed in 30 minutes in three samples of 10 randomly selected math students. Number of practice problems completed in 30 minutes Sample 1 14 15 16 17 16 15 16 15 17 18 Mean = 15.9 Sample 2 16 18 17 14 15 14 18 14 15 16 Mean = 15.7 Sample 3 18 14 16 15 15 14 17 15 19 13 Mean = 15.6 Which statement is most accurate based on the data? A. A prediction based on the data is not completely reliable, because the means are not the same. B. A prediction based on the data is reliable, because each sample has 10 data points. C. A prediction based on the data is not completely reliable, because the means are too close together. D. A prediction based on the data is reliable, because the means of the samples are close together.
Answer:
A
Step-by-step explanation:
The statement which is most accurate based on the data is option(D)A prediction based on the data is reliable, because the means of the samples are close together.
What is Mean?Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers
From the given data,
Mean of the sample 1 = 15.9
Mean of the sample 2 = 15.7
Mean of the sample 3 = 15.6
All three mean are close together.
Therefore the data is reliable
Hence, the statement which is most accurate based on the data is option(D)A prediction based on the data is reliable, because the means of the samples are close together.

Write the equation of a line in slope intercept form given;
(6,-3), (0, 5)
Answer:
[tex]y=(-4/3)x+5[/tex]
Step-by-step explanation:
so you want to start by using y=mx+b
step one: find the slope (remember m is the slope in this)
m= [tex]\frac{y2-y1}{x2-x1}[/tex]
m= [tex]\frac{5+3}{0-6}[/tex]
m= [tex]\frac{8}{-6}[/tex]
m= - [tex]\frac{4}{3\\}[/tex]
step two: insert the value we found for m into the equation and take one of the given points and insert the x and y into the equation (im using (0,5)) and solve for b.
y=mx+b
5= -4/3(0)+b
5=b
step three: rewrite y=mx+b with the values we found for m and for b
[tex]y=(-4/3)x+5[/tex]
Please help me solve these equations. Very confusing.
Step-by-step explanation:
1A (3,-2)
1B
By substitution
[tex]4x - 3y = 18 \\ 2x + y = 4 \\ y = 4 - 2x \\ 4x - 3(4 - 2x) = 18 \\ 4x - 12 + 6x = 18 \\ 10x = 30 \\ x = 3 \\ y = 4 - 2(3) \\ y = 4 - 6 = - 2[/tex]
1C
By elimination
[tex](4x - 3y = 18) -2 \times (2x + y = 4) \\( 4x - 3y = 18) - (4x + 2y = 8) \\ - 5y = 10 \\ y = - 2 \\ 4x - 3 \times ( - 2) = 18 \\ 4x + 6 = 18 \\ 4x = 12 \\ x = 3[/tex]

Answer:
56
Step-by-step explanation:
corresponding angle to 56 is also opposite to x which means it is also 56
Angle opposite to 56 be a
So
a=56(Opposite angles are equal)a and x are corresponding angles
so
a=x=56°The ratio of the sides of a triangle is 2:4:9. If the perimeter is 165 inches, what is the length of the longest side?
Answer:
99inches
Step-by-step explanation:
The ratio of the sides of a triangle =2:4:9.
perimeter = 165 inches,
Total ratio= 2+4+9=15
perimeter = 165
Divide the perimeter by total ratio
165/15=11
Each of the sides
= (2×11) =22
(4×11) =44
(9×11)=99
the length of the longest side= 99inches

find the zeros of p(x)= (x-3)(x+3)(2x+1) HELP PLEAEE
Answer:
3, -3, -1/2
Step-by-step explanation:
There is no need to distribute, just set each parenthesis to equal to zero.
p(x)= (x-3)(x+3)(2x+1)
X-3=0 x+3=0 2X+1=0
+3 +3 -3 -3 -1 -1
X=3 X=-3 2x=-1
x=-1/2
So your answers are 3, -3, -1/2
Write a linear function f with the values f(3)=2 and f(0)=6
Answer:
for f(3)=2 is y=(2/3)x
Step-by-step explanation:
y=ax
and plug x and y into the parent function.
Answer:
f(x) = -⁴/₃x + 6Step-by-step explanation:
f(0) = 6 means y-intercept b = 6
So we have:
f(x) = mx + 6 and f(3) = 2
So:
2 = m×3 + 6
3m + 6 = 2
3m = 2 - 6
3m = -4
m = -⁴/₃
Therefore the function:
f(x) = -⁴/₃x + 6Lightning storms trigger wildfires that burn up a lot of the plants and grasses in the ecosystem. Trees are mostly spared. what is the cause of this?

the triangles are similar. solve for x
Answer:
x= 6.25
Step-by-step explanation:
The hypotenuse of triangle JKL is taken as 96, in the similar way the hypotenuse of triangle JTU is 36. So x can be found by first finding the value of JU, using the Pythagoras theorem.
[tex]a^{2} = b^{2} + c^{2}[/tex]
In this shape the formula will be:
[tex]TU^{2} = JT^{2} + JU^{2}[/tex]
Substitute the given values in the shape into the formula.
TU = 34
JT = 27
TU = Lets take 'y'
[tex]34^{2} = 27^{2} + y^{2}[/tex]
1156 = 729 + [tex]y^{2}[/tex]
[tex]y^{2}[/tex] = 1156 - 729
[tex]y^{2}[/tex] = 427
y = [tex]\sqrt{427}[/tex] = 20.7 ( rounded to 1 decimal place) = 21 (rounded to whole number).
So the original value of JU is '21', but we have to find the value of 'x'. So the expression '-4 + 4x' is equal to 21. This can be written as:
-4 + 4x = 21
4x = 21 + 4
4x = 25
∴ x = [tex]\frac{25}{4}[/tex] = 6.25
x= 6.25
