If there are 52 successful outcomes in a sample with a size of 80, what is the
sample proportion?
A. 0.36
B. 0.72
C. 0.52
D. 0.65

Explanation:

Time progresses without any control over it, so it's something that does not depend on any other factor such as distance. On the other hand, as the time value changes, the distance changes. So the distance is dependent on the time.

The horizontal axis is the x axis, and the x value is always the independent variable. The vertical y axis is the distance. The y value is always the dependent variable.

[tex]r=\frac{5}{9}(y-32)[/tex]

Step-by-step explanation:

The Celsius scale was developed by Swedish astronomer Andres Celsius in 1742. It is used to measure temperature in degree Celsius in which 0 degrees represents the freezing point of water, and 100 degrees represents boiling point of water at the standard atmosphere.

The Fahrenheit scale was proposed in 1724 by the physicist Daniel Gabriel Fahrenheit. It is used to measure temperature in degree Fahrenheit in which 32°F represents the freezing point of water, and 212°F represents boiling point of water at the standard atmosphere.

Let r represent the temperature in degrees Celsius and y represent the temperature in degree Fahrenheit. The relationship between r and y is:

[tex]\frac{r-freezing\ point(^oC)}{boiling\ point\ (^oC)-freezing\ point(^oC)} =\frac{y-freezing\ point(^oF)}{boiling\ point\ (^oF)-freezing\ point(^oF)} \\\\Substituting:\\\\\frac{r-0}{100-0}=\frac{y-32}{212-32}\\\\\frac{r}{100} =\frac{y-32}{180}\\\\r= \frac{y-32}{180}*100\\\\r=\frac{5}{9}(y-32)[/tex]

Similar triangles are those triangles whose corresponding sides are in the same ratio. In the two similar triangles, the value of x is 7.5 units.

Similar triangles are those triangles whose corresponding sides are in the same ratio. And the corresponding angles measure the same. It is denoted by the ‘~’ symbol.

Given that the two of the given triangles are similar triangles. Therefore, the ratio of the sides of the triangle can be written as,

6/x = 8/10

Solving the ratio for x,

x = (6×10)/8

x = 60/8

x = 7.5 units

Hence, in the two similar triangles, the value of x is 7.5 units.

Answer:

66.4°

Step-by-step explanation:

From the question given above, the following data were obtained:

Adjacent = 6 cm

Hypothenus = 15 cm

Angle Y =?

Angle Y can be obtained by using the cosine ratio as illustrated below:

Cos Y = Adjacent / Hypothenus

Cos Y = 6/15

Cos Y = 0.4

Take the inverse of Cos

Y = Cos¯¹ 0.4

Y = 66.4°

Therefore, angle XYZ is 66.4°

Answer:

0.000174

3.5841 x 10^7

4.67  x 10^6

Step-by-step explanation:

1.74 x 10^-4 as an ordinary number

As an ordinary number, the decimal point will be moved 4 times to the left due to the negative power

Hence 1.74 x 10^-4 as an ordinary number

= 0.000174

358.41 x 10^5 in a standard form

In standard form, only one number will be before the decimal point, the number of times the decimal point is moved (to ensure that only the first digit is before the point) is added to the power of ten. Hence

358.41 x 10^5 in a standard form

= 3.5841 x 10^5+2

= 3.5841 x 10^7

4 670 000 in a standard form

As done above, only one digit will be before the decimal

4 670 000 in a standard form

= 4.67  x 10^6

Answer:

67 gallons.

Step-by-step explanation:

To determine how many gallons of a 70% antifreeze solution must be mixed with 90 gallons of 15% antifreeze to get a mixture that is 60% antifreeze, the following calculation must be performed:

0.15 x 90 + 0.70 x 10 = 20.5 / 100 = 0.20

0.15 x 90 + 0.70 x 30 = 34.5 / 100 = 0.34

0.15 x 90 + 0.70 x 60 = 55.5 / 100 = 0.55

0.15 x 90 + 0.70 x 67 = 60.4 / 100 = 0.60

Thus, 67 gallons of 70% antifreeze solution will be needed to achieve a 60% mix of that solution.

Step-by-step explanation:

Answer: the bridge is 11.025 m high

Step-by-step explanation:

Given that;

Time taken to hit the water t = 1.5 sec

height of bridge = ?

lets take a look at the equation of motion;

y(t) = y₀ + (1/2)at²

with initial velocity zero and we know that acceleration due to gravidity is 9.8m/s

we substitute

y(t) = (1/2)gt² = (1/2) × 9.8 × (1.5)²

y(t) = (1/2)gt² = (1/2) × 9.8 × (1.5)²

y(1.5) = 11.025 m

Therefore, the bridge is 11.025 m high

Answer:

∠J=85°

Step-by-step explanation:

Theory to know when answering this question:

1. The sum of the angles in a quadrilateral (shape with four sides) is 360°

2. Similar shapes have the same angles

Point 1 tells us that ∠P+∠Q+∠S+∠R=360

Point 2 tells us that ∠F=∠P, ∠G=∠Q, ∠J=∠S, and ∠H=∠R.

∴∠F+∠Q+∠J+∠R=360

109+122+∠J+44=360

∠J=360-275=85°

Hi!

So, to "half" a number, you multiply it by 1/2 or 0.5

"A number" is a number which we don't know the value of, so we could use a variable. Any letter you want is fine, but let's use x

"Decrease by 12" This simply means to subtract 12, so - 12

So, now we have:

1/2x - 12

Answer:

1. The mistake was the sign that was put negative instead of positive.

2. y = 4

Step-by-step explanation:

​In the first response box, enter the number of the step where the mistake is made.

​Step:

The mistake is on step 1: This is the distributive property, however it was distrubuted wrong since the signs were used wrong.

-4(6-y)+4=-4 does not equal  -24-4y+4=-4

The reason is because -4 x -y is not equal to -4y because negative x negative = positive. So, it's equal to +4y.

In the second response box, enter the correct solution to the problem.​

Problem: -4(6-y)+4=-4

Step 1: -24 + 4y + 4 = -4 (Distributive Property Of Equality)

Step 2: -20 + 4y = -4 (Combine Like Terms)

Step 3: 4y = 16 (Addition Property Of Equality)

Step 4: y = 4 (Division Property Of Equality)

If Y = 5 and the X is = 1 then Y = 125 is X = 25

Answer:

29.92 miles per hour

87,089.76 metric tonnes

Step-by-step explanation:

Given that the top speed is 26 knots, recall that

1 knot = 1.15078 miles per hour

Hence,

26 knots = 26 * 1.15078

= 29.92028 miles per hour

To 2 decimal places

=29.92 miles per hour

Given that the boat has a  displacement of approximately 96000 tons, in metric tonnes...

Recall that

1 ton = 0.907185 metric tonnes

As such,

96000 tons = 0.907185 * 96000

= 87,089.76 metric tonnes
