Answer:
C.) In perfect health.
Step-by-step explanation:
Given an average weight of 15kg and a standard deviation of 3kg for children of 4 years. Since the weight is based on a normal Z - distribution of 95% which is mean ± 2(standard deviations)
Mean weight interval is :
15 - 2(3) ; 15 + 2(3)
(9 ; 21) ; this weight interval could be interpreted to mean the normal or perfect weight value.
Therefore, given that the child weighs 12kg
Since, 12 kg falls within in the interval, we can conclude that the child is in perfect health.
If the slope of a strictly increasing function at the point (a, b) is 6, what is the slope of the inverse of the function at the point (b, a)?
A) -6
B) 1/6
C) -1
D) The slope cannot be determined
Answer:
Step-by-step explanation: you add the slope by A and B and convert it to point on the graph and your answer will be A=-6

Answer:
C) f(x)=25(4/5)^x
Step-by-step explanation:
Observe that the exponential function is decreasing (so exponential decay). This means that r<1 making A and D wrong as they show exponential growth as r>1. Also notice that the y-intercept is 25 which is where the function crosses the y-axis when x=0. This means C is the only correct answer.

Angle A is 71 degrees. What is the measure of its supplement?
The measure of supplement of angle A is 109°.
Here,
Measure of angle A is 71°.
We have to find the supplement of angle A.
What are Supplementary angles?
Two angle are called supplementary angles if sum of both angles are 180°.
Now,
Measure of angle A is 71°.
Let the measure of its supplement is x°.
Then, By definition of supplementary angles;
x° + 71° = 180°
x° = 180° - 71°
x° = 109°
Therefore, The measure of supplement of angle A is 109°.

Convert the following degree measure to radian measure.
48°20'
9514 1404 393
Answer:
29π/108 radians ≈ 0.843576 radians
Step-by-step explanation:
There are 60 minutes (60') in a degree, so your angle in degrees is ...
48°20' = (48 20/60)° = (48 1/3)° = (145/3)°
There are π/180 radians in 1 degree, so the number of radians is ...

Adding and Subtracting with Rational Numbers
The elevation we call sea level is actually the average level of the sea. This means that at average sea level, the elevation is zero. In reality, the level of the sea rises and falls in what are called tides. Low tide is the point of lowest sea level in a tidal period. High tide is the point of highest sea level in a tidal period. The height above or below average sea level is called elevation. An elevation below sea level is considered a negative value, while an elevation above sea level is positive.
Winston lives near the ocean. He regularly brings an altimeter to the beach to measure the elevation of the ocean’s surface. You will use the data Winston gathered to complete tasks about the rising and falling of the ocean’s surface. When necessary, sketch a diagram of the situation on a separate sheet of paper to assist you.
On Monday at 1 p.m., when the ocean’s surface was at an elevation of 2.2 feet, Winston went to a surf shop that was 8.2 feet above the ocean’s surface. At 7 p.m. when the ocean’s surface was at an elevation of -2.4 feet, Winston ate dinner at a restaurant whose deck was 10 feet above the ocean’s surface.
Part A
What was the net change in the elevation of the ocean’s surface from 1 p.m. to 7 p.m.?
Part B
How many feet apart are the two ocean elevations described in part A?
Part C
What is the elevation of the deck where Winston ate dinner?
Part D
What is the elevation of the surf shop?
Part E
What was the distance between the deck and the ocean’s surface at 1 p.m.? Which was higher, the deck or the ocean?
Part F
What was the distance between the surf shop and the ocean’s surface at 7 p.m.? Which was higher, the surf shop or the ocean?
plzzz help 100 points
Answer:
Part ANet change is the change compared to zero level
From positive 2.2 feet to negative 2.4 feetPart BThe distance between the elevations
2.2 + 2.4 = 4.6 feetPart C 10 feetPart D 8.2 feetPart EPositive elevation brings the level close to the deck
8.2 - 2.2 = 6 feetPart FNegative elevation takes the level apart from the elevation of the surf shop
10 - (-2.4) = 12.4 feetThe surf shop was higherAnswer:
Answers :-Part A
It changed from 2.2 ft to -2.4 ft
Part B
Distance between elevation => Ocean elevation A + Ocean Elevation B = 2.2 + 2.4 = 4.6 ft
Part C
Winston ate dinner at a restaurant whose deck was 10 feet above the ocean’s surface.
Part D
In the sentence "Winston went to a surf shop that was 8.2 feet above the ocean’s surface". So, 8.2 ft
Part E
Height of shop - Height of elevation at top
=> 8.2 - 2.2 = 6 ft
Part F
12.4 ft is the height of surf shop
Surf shop was Higher

B.
No, because it is still less likely to have an outcome of drawing a Twix.
C.
Yes, because there are still only two possible outcomes.

Answer:
A
Step-by-step explanation:
There are more options of the Snickers than the Twix. Therefore meaning, it is a 4/5 chance of it being Snickers and a 1/5 chance of it being Twix.

Which of these is a function in standard from that represents the data?
0 4x + - 04x2 + 3
4x2 + -.04x + 3
O 3 + 4x2 - 04x
0 -0.4x2 + 4x + 3
The quadratic function that represents the data is given as follows:
y = -0.04x² + 4x + c.
How to obtain the quadratic function?The standard definition of a quadratic function is given as follows:
y = ax² + bx + c.
From the table, when x = 15, y = 54, hence:
a(15)² + 15b + c = 54
225a + 15b + c = 54
When x = 30, y = 87, hence:
a(30)² + 30b + c = 87
900a + 30b + c = 87
When x = 45, y = 102, hence:
a(45)² + 45b + c = 102
2025a + 45b + c = 102
Then the system of equations used to obtain the coefficients is given as follows:
225a + 15b + c = 54900a + 30b + c = 872025a + 45b + c = 102Using a calculator, the coefficients are given as follows:
a = -0.04, b = 4 and c = 3.
Hence the function is:
y = -0.04x² + 4x + c.

Is (-3,5) the solution to x=5y-20
Answer:
Yes
Step-by-step explanation:
Answer:
no
Step-by-step explanation:
First, we need to plug in the ordered pair inside the equation with -3 as x and 5 as y.
-3=5(5)-20 Multiply 5 times 5.
-3=25-20 Subtract 20 from 25.
-3=5
-3 does not equal 5, so the ordered pair is not a solution.
