Answer:
62.5%
Step-by-step explanation:
Split the time up into 5 minute slots. That gives us 24 slots of 5 minutes.
20/5=4 of the 5 minute slots playing outside
25/5=5 of the 5 minute slots on his phone
5+4=9 out of 24 slots spent
24-9=15 slots remaining to play his instrument
15/24x100=62.5% time playing instrument

Supposed B is the midpoint of line AC. Use the given information to find the missing measure. AB = 6Y -14, BC = 10-2Y 2Y, what is AC
Given:
B is the midpoint of line AC.
[tex]AB=6Y-14[/tex]
[tex]BC=10-2Y[/tex]
To find:
The length of AC.
Solution:
It is given that B is the midpoint of line AC. So,
[tex]AB=BC[/tex]
[tex]6Y-14=10-2Y[/tex]
[tex]6Y+2Y=10+14[/tex]
[tex]8Y=24[/tex]
Divide both sides by 8.
[tex]Y=\dfrac{24}{8}[/tex]
[tex]Y=3[/tex]
The value of Y is 3.
Now,
[tex]AC=AB+BC[/tex]
[tex]AC=6Y-14+10-2Y[/tex]
[tex]AC=4Y-4[/tex]
Putting [tex]Y=3[/tex], we get
[tex]AC=4(3)-4[/tex]
[tex]AC=12-4[/tex]
[tex]AC=8[/tex]
Therefore, the length of AC is 8 units.

I will give branily to whoever is right
Answer:
The distance is 4
Step-by-step explanation:
Given:
x1 = 7
x2 = 7
y1 = -1
y2 = -5
[tex]d=\sqrt{(x2-x1)^2+(y2-y1)^2} \\\\d=\sqrt{(7-7)^2+(-5+1)^2}\\\\d=\sqrt{(0)^2+(-4)^2} \\\\d=\sqrt{0+16} \\\\d=\sqrt{16} \\d=4[/tex]
Answer:
4 units
Step-by-step explanation:
the distance between two points is given by,
[tex]D = \sqrt{{(x_{1}-x_{2})}^{2} + {(y_{1}-y_{2})}^{2} } \\x_{1}=7; x_{2}=7; y_{1}=-1; y_{2}=-5\\D=\sqrt{{([7]-[7])}^{2} + {([-1]-[-5])}^{2} }\\D=\sqrt{{(0)}^{2} + {(4)}^{2} }\\D=\sqrt{0 + 16 }\\D=\sqrt{16}\\D=4[/tex]

The triangle in the given image is a right angled triangle.
By Pythagoras theorem,
x² + 12² = ( x + 6 )²
x² + 144 = x² + 36 + 12x
x² - x² = 36 - 144 + 12x
0 = - 108 + 12x
12x = 108
x = 108 / 12
x = 9

A triangle has vertices A(-2,1), B(2,4), C(4,1).
Find the area of the triangle.
Answer: 6 units squared
Step-by-step explanation: ok here is how you do it so you make the triangle like I did and once you make it. You count the squares about how long it is and how high it is in this case I got for the base 6 and the height 2 so we multiply to get 12 also we divide 12 and 2 to get 6 units squared there you go. hope this helps.

Aidan makes 12 bracelets on Monday. He makes 8 more bracelets each day from Tuesday through Thursday. How many bracelets does Aidan have in all by the end of the day on Thursday? *
5 points
Answer:
He makes 44 bracelets on Friday.
Brainly me or heart if this helped!
Answer:
36 bracelets
Step-by-step explanation:
12+(3*8)=x
12+24=36
Aidan originally started with 12 bracelets. He makes 8 Tuesday through Thursday, which is three days. 8 * 3 is 24 plus 12 equals 36.
A student believes that a certain number cube is unfair and is more likely to land with a six facing up. The student rolls the number cube 45 times and the cube lands with a six facing up 12 times. Assuming the conditions for inference have been met, what is the 99% confidence interval for the true proportion of times the number cube would land with a six facing up?
0.27 plus-or-minus 2.58 StartRoot StartFraction 0.27 (1 minus 0.27) Over 45 EndFraction EndRoot
0.73 plus-or-minus 2.33 StartRoot StartFraction 0.73 (1 minus 0.73) Over 45 EndFraction EndRoot
0.27 plus-or-minus 2.33 StartRoot StartFraction 0.27 (1 minus 0.27) Over 45 EndFraction EndRoot
0.73 plus-or-minus 2.58 StartRoot StartFraction 0.73 (1 minus 0.73) Over 45 EndFraction EndRoot
Answer: Option #1
Step-by-step explanation:
99 % confidence level - so it has to be 2.58 not 2.33 ( thats 98% confidence level )
then 12times facing u out of 45 times .... 12/45= .27
Option #1 : 0.27 +/- 2.58 StartRoot StartFraction 0.27 (1 minus 0.27) Over 45 EndFraction EndRoot
The 99% confidence interval for the true proportion of times the number cube would land with a six facing up is 0.27 plus-or-minus 2.58 StartRoot StartFraction 0.27 (1 minus 0.27) Over 45 EndFraction EndRoot.
What is Confidence Interval?This is an operation which is used to measure probability that a parameter will fall between a pair of values around the mean
99 % confidence level is closer to 2.58 and 12 times facing up out of 45 times which is 12/45= .27
Hence the reason why option A was chosen as the most appropriate choice.
A quadrilateral has vertices at (1.4).
(7,3), (3, -5), and (8,4). The
quadrilateral is dilated by a scale
factor of 3.5 with the origin as its
center. What are the coordinates of
the vertices of the image of the
quadrilateral?
Given:
A quadrilateral has vertices at (1,4), (7,3), (3, -5), and (8,4).
The quadrilateral is dilated by a scale factor of 3.5 with the origin as its center.
To find:
The coordinates of the vertices of the image of the quadrilateral.
Solution:
If a figure is dilated by a scale factor k with origin as it center, then
[tex](x,y)\to (kx,ky)[/tex]
It is given that the quadrilateral is dilated by a scale factor of 3.5 with the origin as its center. So, the rule of dilation is
[tex](x,y)\to (3.5x,3.5y)[/tex]
Using this rule, we get
[tex](1,4)\to (3.5(1),3.5(4))[/tex]
[tex](1,4)\to (3.5,14)[/tex]
Similarly,
[tex](7,3)\to (3.5(7),3.5(3))[/tex]
[tex](7,3)\to (24.5,10.5)[/tex]
[tex](3,-5)\to (3.5(3),3.5(-5))[/tex]
[tex](3,-5)\to (10.5,-17.5)[/tex]
And,
[tex](8,4)\to (3.5(8),3.5(4))[/tex]
[tex](8,4)\to (28,14)[/tex]
Therefore, the coordinates of the vertices of the image of the quadrilateral are (3.5,14), (24.5,10.5), (10.5,-17.5), (28,14).
