Answer:
The triangle will not be possible.
this is because two side lengths can't expand 14 units.
in order for the triangle to work, the sum of the two short side lengths must be greater than the longer side.
however, 6+6 does not equal 14 it equals 12 this means that the triangle is not possible

Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield x overbarequals103.29, y overbarequals103.75, requals0.899, P-valueequals0.000, and ModifyingAbove y with caret equals negative 9.5 plus 1.1 x, where x represents the IQ score of the younger child. Find the best predicted value of ModifyingAbove y with caret given that the younger child has an IQ of 105? Use a significance level of 0.05.
Answer:
106
Step-by-step explanation:
Given :
Number of the set of siblings = 20
This 20 pair yields [tex]$\overline x$[/tex] = 103.29, [tex]$\overline y$[/tex] = 103.75, requals = 0.899, P-value = 0.000
Let x represents the IQ score of the younger child.
And y is the predicted value of Y(^).
So according to the question,
x = 105
and y = -9.5 + 1.1 x
Then,
y = -9.5 + 1.1 (105)
y = -9.5 + 115.5
y = 106
So the best predicted value of Y(^) is 106
Jamie wants to make an 80, or B, test average in her class. She scored 75 and 82 on her last 2 tests. What is the lowest grade she can make on her last test to finish with an 80 test average?
Answer:
Its probably too late now but the answer is 83
Step-by-step explanation:
83 is the lowest grade she can make on her last test to finish with an 80 test average.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Given that Jamie wants to make an 80, or B, test average in her class.
She scored 75 and 82 on her last 2 tests.
we need to find the lowest grade she can make on her last test to finish with an 80 test average
Let x be the e lowest grade she can make on her last test to finish with an 80 test average
75+82+x/3=80
157+x=240
Subtract 157 from both sides
x=83
Hence, 83 is the lowest grade she can make on her last test to finish with an 80 test average.

How many flowers, spaced every 6 in., are needed to surround a circular garden with a 100-ft radius?
Answer:
Number of flowers required = 1256
Step-by-step explanation:
Circumference of a circle is given by the formula,
Circumference = 2πr
Here, r = radius of the circle
For a circle with radius = 100 in.
Therefore, circumference = 2π(100)
= 200π
= 628.32 ft
Distance between each flower = 6 in
≈ [tex]\frac{6}{12}[/tex]
= 0.5 ft
Number of flowers = [tex]\frac{\text{Circumference}}{\text{Space between each flower}}[/tex]
= [tex]\frac{628.32}{0.5}[/tex]
= 1256.63
≈ 1256
Therefore, number of flowers required = 1256

In a trapezoid, the length of one base is equal to its height and the length of the other base is twice its height. If the height is 10 centimeters, what is the area of the trapezoid?
Explain how you found your answer.
Enter the correct answers in the boxes.
Answer:
150cm²
Step-by-step explanation:
In a trapezoid, the length of one base is equal to its height and the length of the other base is twice its height. If the height is 10 centimeters, what is the area of the trapezoid?
The formula for the area of a trapezoid = 1/2(a + b) h
Where a = Length of the first base
b = Length of the second base
h= height of the trapezoid
h = 10cm
The length of one base is equal to its height
Hence:
a = h = 10cm
The length of the other base is twice its height.
b = 2h
h = 10cm
b = 10 × 2 = 20cm
Therefore, the Area of the Trapezoid =
1/2 (20 + 10)10
1/2 × 30 × 10
= 150cm²

A quality control manager samples 700 LED bulbs and finds defects in 8 of them. What is the probability that a bulb selected at random will have a defect?
Answer: 0.0114
Step-by-step explanation:
Since we are given the information that the quality control manager samples 700 LED bulbs and finds out that 8 bulbs have defects in them.
The probability that a bulb selected at random will have a defect will be calculated as follows:
= Number of defected bulbs / Total number of bulbs sampled
= 8/700
= 0.0114
Therefore, the probability is 0.0114.
Christopher needs to buy wooden boardes to build a box that is 12 inches long, 6 inches wide, and 8 inches high. How many square inches of wooden boards is needed to build the box
Answer:
432 in²
Step-by-step explanation:
To Obtian the square inches of wooden boards required :
Area of box = 2(l * w) + 2(l * h) + 2(h * w)
Length = 12 ; width = 6 ; height = 8
Hence,
Area of box = 2(12 * 6) + 2(12 * 8) + 2(8 * 6)
Area of box = 2(72) + 2(96) + 2(48)
Area of box = 432 in²

Length of string Claire in end = [tex]1\frac{5}{6}[/tex] feet = 11 / 6 feet
Length of string used by Claire = Length of string Claire in starts - Length of string Claire in end
Length of string used by Claire = [25 / 6] - [11 / 6]
BY taking LCM
Length of string used by Claire = [25 - 11] / 6
Length of string used by Claire = 14 / 6
Length of string used by Claire = 7 / 3 feet

Step-by-step explanation:
Given:
Radius (r) = 9
π = 3.14
Required:
Arc length
Solution:
Arc length = θ/360 × 2πr
θ = 180° (half of a circle = 180°)
Plug in the values into the formula
Arc length = 180/360 × 2 × 3.14 × 9
Arc length = ½ × 56.52
Arc length = 28.26 units

Is (2, 10) a solution to the system?
Answer:
No, (2, 10) is not a solution to the system
Step-by-step explanation:
The given set of equations are -
-3X - 4Y = 4 --- Eq(1)
-52X + Y = 2--- Eq (2)
Multiplying equation 2 by 4, we get
-3X - 4Y = 4 --- Eq(1)
4 *(-52X + Y = 2)--- Eq (2)
-3X - 4Y = 4 --- Eq(1)
-208X + 4Y = 8--- Eq (2)
Now we will add equation 1 and 2
-211 X = 12
X = 12/211
Hence, the given set of solution does not fit for the given two equations
