Answer:

Out of the 6 observations when the temperature is between 90 and 99, 2 are on Thursday.

2/6 = 33%

Out of the 4 observations when the temperature is less than 90, 1 was on Monday.

1/4 = 25%

Out of the 26 observations when the temperature is greater than 89, 4 were on Friday.

4/26 = 15%

Out of the 6 observations when the temperature is between 90 and 99, 2 are on Thursday.

2/6 = 33%  

Out of the 1 observation when the temperature is between 110 and 120, none were on Sunday.

To calculate probabilities of certain observations concerning different variables, we need relevant data pertaining to those variables. Without this data, it's challenging to calculate precise probabilities. In such cases, we use the closest available data or make educated assumptions.

To find the probability of different observations, we need specific data that relates to those situations. For example, to find the probability that an observation is on a Thursday when the temperature is between 90 and 99, we would need historic data that captures temperature observations on Thursdays. Similarly, other probabilities also need specific data. For instance, to know the probability of an observation being on a Monday with temperature less than 90, or a Friday where the temperature is greater than 89, we would need historic temperature measurements for these specific days. However, since the provided information doesn't include specific data needed to calculate the probabilities asked in the question, we can't provide precise probabilities. Probability in statistics is generally calculated based on relevant data that is representative of the situation of interest. In situations where it is necessary to estimate the probability without access to specific data, we might use available data that is as closely matching as possible, or might make educated assumptions.

Answer:

  D.  y = -1/5x +32/5

Step-by-step explanation:

The equation of the line passing through point (h, k) with slope m can be written ...

  y = m(x -h) +k

Filling in your given values, the equation is ...

  y = -1/5(x -(-3)) +7

  y = -1/5x -3/5 +7 . . . . eliminate parentheses

  y = -1/5x +32/5 . . . . . combine constants

Answer:

e.

Step-by-step explanation:

Each side is multiplied by 5.

It is the multiplication property of equality.

x^2 = 4 -7x

Need to rewrite the equation in quadratic form.

Add 7x to each side:

x^2 +7x = 4

Subtract 4 from each side:

x^2 + 7x - 4 = 0

Now using the quadratic formula -b +/-√(b^2-4(ac)) / 2a

We can solve for x.

a = 1, b = 7 and c = -4

Replace the letters with their values:

-7 +/- √(7^2 -4(1-4)) / 2*1

Simplify:

-7 +/- √65 /2

The exact answers are:

X = -7 + √65 / 2 and X = -7 - √65 / 2

Answer:

X = -7 + √65 / 2 and X = -7 - √65 / 2

Answer:

f(c) =17.12c -14.56c + 5.40(.5c) - 1.20(.5c)

Step-by-step explanation:

Profit is the difference between revenue (17.12c +5.40(.5c)) and cost(14.56c+1.20(0.5c)). That difference is expressed by the function shown above.

Answer:

f(c) =17.12c -14.56c + 5.40(.5c) - 1.20(.5c)

Step-by-step explanation:

Let's build the f(c) function by steps.

There are c customers.

John has found that on average, each meal served costs the restaurant $14.56 and takes in $17.12.

So, the costs for the restaurant are negative, and what takes positive.

f(c) =17.12c -14.56c

Now the final part

John has also found that on average, each beverage served costs the restaurant $1.20 and takes in $5.40.

Half of these customers order a beverage, and this is why we multiply by 0.5.

So

f(c) =17.12c -14.56c + 5.40(.5c) - 1.20(.5c)

4. His percentage is 79% so making each shot is 79%

Multiply the percent for each shot for each shot:

Making two shots = 0.79 x 0.79 = 0.624 = 62.4% Round the answer to 62% if needed.

5. They have 4 different flavors and 6 different toppings.

a. Picking vanilla is 1 out of 4 = 1/4 and picking chocolate chips is 1 out of 6 = 1/6.

The probability of picking both is 1/4 x 1/6 = 1/24

b.  There are a total of 10 different things to pick.

Picking chocolate ice cream is 1 out of 10 = 1/10, picking marshmallow topping is 1 out of 10 = 1/10

Picking one or the other would be 2 out of 10 = 2/10 which reduces to 1/5

Answer:

4. 79%

5. 1/24 and 1/5 for part a and b

The answer is:

The correct option is the third option;

[tex]-23\leq t\leq 50[/tex]

To find which of the options expresses the intersection of the three days as an inequality in terms of temperature "t" we need to find an inequality which starts at the lowest temperature (greater or equal) and finish at the highest temperature (less or equal).

So, we have that the lowest temperature is -23°F and the highest temperature is 50°F, there are two options for that range, but we need to consider that the temperature will range from -23° to 50°, so, the correct option is the third option;

[tex]-23\leq t\leq 50[/tex]

We can see that the inequality express that the temperature will range from -23°F being greater or equal than that, to 50°F being less or equal than that.

Have a nice day!

The original statement is true only if:

Options a and d are equivalent:

[tex]P\implies Q \iff \lnot Q \implies \not P[/tex]

and they both are true in the same cases as above.

Option c is also fine, because it is false only if both England and Africa are both countries, just like the original statement.

Option b, instead, is true only if neither of the two options are countries, so it doesn't cover the cases where only one of the two is a country.

Answer:

Step-by-step explanation:

The area of a parallelogram is given by

[tex]A=bh[/tex]

Now, if we consider the 9.9 inches side as the base, then the height is the one labeled with 5.5 inches.

If instead we choose the 11 inches side as the base, the height is h.

So, we can express the area in this two equivalent ways:

[tex]A = 9.9\cdot 5.5 = 11\cdot h[/tex]

Solving for h, we have

[tex]h = \dfrac{9.9\cdot 5.5}{11} = 4.95[/tex]

Answer:

  42 ft/s

Step-by-step explanation:

The change in velocity is given by the area under the curve from t=0 to t=6. The average acceleration over that period is (10+4)/2 = 7 ft/s^2, so the change in velocity is ...

  (7 ft/s^2)(6 s) = 42 ft/s

The velocity of the car at t=6 is 42 ft/s.

The velocity of the car at t=6 is 42 ft/s.

The change in velocity is given by the area under the curve from t=0 to t=6. The average acceleration over that period is [tex](10+4)/2 = 7 ft/s^2[/tex], so the change in velocity is ...

[tex](7 ft/s^2)(6 s) = 42 ft/s[/tex]

b is the length side of the square

h is the height of the pyramid

we have

Step-by-step explanation:

In slope intercept form, y = mx + b, the m is the slope, the b is the y intercept, and x and y can be subbed in from the point you are given of (1, 3).  We are told the slope, so everything we have fills in like this:

[tex]3=\frac{1}{4}(1)+b[/tex]

Now we just need to solve for b:

[tex]3-\frac{1}{4}=b[/tex] and

[tex]\frac{12}{4}-\frac{1}{4}=b[/tex] so

[tex]b=\frac{11}{4}[/tex]

Answer:   [tex]32\pi[/tex] cubic units.

Step-by-step explanation:

You can use this formula for calculate the volume of a cone:

[tex]V_{cone}=\frac{1}{3}\pi r^2h[/tex]

Where "r" is the radius and "h" is the height.

You know that the diameter of the base of the cone measures 8 units, then, the radius can be found by dividing the diameter by 2:

[tex]r=\frac{8units}{2}\\\\r=4units[/tex]

Since you already know that height and  the radius, you can substitute them into the formula. Then, the volume of this cone is:

[tex]V_{cone}=\frac{1}{3}\pi (4units)^2(6units)[/tex]

[tex]V_{cone}=32\pi \ units^3[/tex]

Answer:

16.6 in

Step-by-step explanation:

The volume (V) of a pyramid is

V = [tex]\frac{1}{3}[/tex] area of base × h

where h is the perpendicular height and area of base = 14² = 196

here V = 980, so

[tex]\frac{1}{3}[/tex] × 196h = 980 ( multiply both sides by 3 )

196h = 2940 ( divide both sides by 196 )

h = 15

Consider the right triangle formed by the height h from the vertex to the midpoint of the base and the slant height (s) ← the hypotenuse

Using Pythagoras' identity in the right triangle

s² = 15² + 7² = 225 + 49 = 274 ( take the square root of both sides )

s = [tex]\sqrt{274}[/tex] ≈ 16.6

Answer:

tire A=39 revolutions

tire B=38 revolutions

tire C= 37 revolutions

Step-by-step explanation:

The question is on circumference

Tire A diameter = 15 +4.60+4.60=24.20 inches

Tire B diameter= 16+4.43+4.43=24.86 inches

Tire C diameter=17+4.33+4.33=25.66 inches

Finding the circumference/single revolution

Tire A = 2×3.14×24.20=151.98 inches

Tire B= 2×3.14×24.86=156.12 inches

Tire C=2×3.14×25.66=161.15 inches

Number of revolutions made

Track length=500 feet.............change feet to inches

500×12=6000inches

Revolutions for tire A= 6000/151.98 =39.47⇒39 revolutions

Revolutions for tire B=6000/156.12 =38.43⇒38 revolutions

Revolutions for tire C= 6000/161.15 =37.23⇒37 revolutions
