Answer:
A. 122
Step-by-step explanation:
in right-angle triangle,
AB² + AC² = BC²
22²+120² = BC²
2²×11² + 2⁶×5²×3²= 2²(121+16×25×9)
4(121+3600) = 14884
BC=√14884 = 122

Anna went to the playground at 4:05 P.M. She played on the slide for 30 minutes and the swings for 55 minutes, then went home. What time was it when Anna left the playground?
Include A.M. or P.M. in your answer (for example, 11:58 A.M.).
Answers
Answer:
5:30 P.M.
Step-by-step explanation:
30 (slide) minutes and 55 (swings) minutes. These numbers (time-wise) total up to an hour and 25 minutes. Adding this to 4:05 P.M. would mean that she left the playground at 5:30 P.M.

and
σ
=

. You intend to draw a random sample of 36 items from this population.
Find the probability that the mean of this sample is less than 105.4.
Answers
The probability that the mean of this sample is less than 105.4 is 14.46%
The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } \\\\x=raw\ score, \sigma=standard\ deviation, \mu=mean,n\ is\ sample\ mean\\\\\\Given\ that\ \sigma=45,\mu=124.5,n\ =36,hence:\\\\For\ x<105.4:\\\\z=\frac{105.4-124.9}{45/\sqrt{36} }=-1.06[/tex]
From the normal distribution table, P(x < 105.4) = P(z < -1.06) = 0.1446 = 14.46%
The probability that the mean of this sample is less than 105.4 is 14.46%

Find the rate if a principal of $1,800 earned $378 interest in 6 years
Answers
Answer:
Interest rate (r ) = 0.035 or 3.5%
Step-by-step explanation:
Given the principal amount of $1,800, and an interest payment of $378 earned in 6 years:
Use the simple interest formula and algebraically solve for variable, interest rate, r :
I = P × r × t
Where:
I = interest payment = $378
P = principal amount = $1,800
t = time (in years) = 6
r = interest rate
Divide both sides by P × t to isolate r :
[tex]\displaytext\sf{\frac{I}{P\:\times\:t}\:=\:\frac{P\:\times\:r\:\times\:t}{P\:\times\:t}}[/tex]
[tex]\displaytext\sf{interest\:rate\:(r)\:=\:\frac{I}{P\:\times\:t}}[/tex]
Substitute the given values into the formula for the interest rate:
[tex]\displaytext\sf{interest\:rate\:(r)\:=\:\frac{378}{1800\:\times\:6}\:=\:\frac{378}{10800}}[/tex]
Interest rate (r ) = 0.035 or 3.5%
Therefore, the interest rate is 3.5%.

Amy graphed a point to represent the absolute value of a number on a number line. If the original number is less than −10, describe all the possible values for the point Amy graphed on the number line.
Answers
Answer:
x>= 11 or x>10
Step-by-step explanation:
Absolute value can be used to represent the positive counterpart of a negative number. In this case, we are asked to find a number that is less than -10, meaning from -11 to negative infinity. Since we are asked to take absolute value, we would take |-11| which equals 11, and |-∞| = ∞.
So Amy graphed a value on the number line that is greater than or equal to 11, or any value greater than 10.
*Infinity is not a real number, it represents the largest number possible, which doesn't exist since numbers can continue on forever, so it can be disregarded.*

Answer:
x = 7 and y = -8 ordered pair is (7, -8)
Step-by-step explanation:
0.1x + 0.3y = - 1.7
0.3x - 0.5y = 6.1
Solving the first equation for x 0.1x = -0.3y - 1.7
0.1x/0.1 = -0.3y/0.1 - 1.7/0.1
x = -3y - 17
Substitute into the second equation.
0.3(-3y - 17) - 0.5y = 6.1
-0.9y - 5.1 - 0.5y = 6.1
-1.4y - 5.1 = 6.1
-1.4y = 5.1 + 6.1
-1.4y = 11.2
y = 11.2/-1.4
y = -8
Substitute y into the first equation and solve for x
x = -3y - 17
x = -3(-8) - 17
x = 24 - 17
x = 7

Hey everyone! This questions is tricky for me so can anybody help me out?

Answers
g(x) = 2x^2
for g(- 4), you just plug in - 4 for x
g(- 4) = 2(- 4)^2
g(- 4) = 2(16)
g(- 4) = 32
Answer:
g(-4) = 32
Step-by-step explanation:
Given the quadratic function, g(x) = 2x², finding the output value given g(-4) involves substituting the value of the input, x = -4, into the function.
Solution:g(x) = 2x²
g(-4) = 2(-4)² = 2(-4)(-4)
g(-4) = 2(16)
g(-4) = 32
Therefore, g(-4) = 32.
