Answer:

SA = 48 cm²

Step-by-step explanation:

the surface area (SA) is the sum of the areas of the 5 faces.

1 square and 4 congruent triangles form the pyramid

area of square = 4 × 4 = 16 cm²

area of triangle = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

here b = 4 and h = 4

area = [tex]\frac{1}{2}[/tex] × 4 × 4 = 2 × 4 = 8 cm²

area of 4 triangles = 4 × 8 = 32 cm²

SA = 16 + 32 = 48 cm²

If professor Snozz earns 8% of "total-sales", then the amount that the professor make on selling of 300 copies is $708.

In order to find out how much Professor Snozz makes, we first calculate the "total-sales" revenue of the 300 copies of the book;

⇒ Total sales revenue = (number of copies sold) × (price per copy),

⇒ Total sales revenue = 300 × $29.50,

⇒ Total sales revenue = $8850;

Next, we calculate amount of royalty that Professor Snozz earns, which is 8% of the total sales revenue;

So, Royalty = 8% of "Total sales revenue";

⇒ Royalty = 0.08 × $8850,

⇒ Royalty = $708;

Therefore, Professor Snozz earns $708 as a royalty for selling 300 copies of his book.

a) The probability that exactly one of them will be a girl = 0.3407

b) The probability that at least one of them will like the football = 0.7672

a) If we select three students then the probability that exactly one of them will be a girl

From the attached two way table we can observe that the total number of girls = 22

the total number of boys = 18

and the total number of students = 40

The possible outcomes for selecting 3 students from 40 would be,

⁴⁰C₃

Using combination formula,

⁴⁰C₃ = 40! / (3! × (40 - 3)!)

      = 9880

If there is exactly one girl then other two must be boys in the set of 3 selected students.

So, the required probability would be,

P = (²²C₁ × ¹⁸C₂) / ⁴⁰C₃

P = (22 × 153)/9880

P = 0.3407

b) The number of students like the football = 15

and the number of students who don't like the football are 40 - 15 = 25

The probability that at least one of them will like the football would be,

P = (¹⁵C₃ × ²⁵C₀ + ¹⁵C₂ × ²⁵C₁ + ¹⁵C₁ × ²⁵C₂) / ⁴⁰C₃

Answer:

To find g(26) when g(x) = 7x + 2, we simply need to substitute x = 26 into the expression for g(x):

g(26) = 7(26) + 2

g(26) = 184

Now, to find (g of f)(x), we need to substitute f(x) into the expression for g(x):

(g of f)(x) = g(f(x)) = 7(f(x)) + 2

Since f(x) = x - 2, we can substitute x - 2 for f(x) in the expression for g(x):

(g of f)(x) = g(x - 2) = 7(x - 2) + 2

Simplifying this expression, we get:

(g of f)(x) = 7x - 12

Now, to find (g of f)(26), we simply substitute x = 26 into the expression we just found:

(g of f)(26) = 7(26) - 12

(g of f)(26) = 182

Therefore, the answer is A) (not listed).

If the temperature outside is 86°F and the relative humidity is 55%, the heat index is: C. 89°F.

In this scenario, the relative humidity would be plotted on the x-axis (x-coordinate) of the scatter plot while the heat index would be plotted on the y-axis (y-coordinate) of the scatter plot through the use of Microsoft Excel.

From the scatter plot which models the relationship between the x-values and y-values, a quadratic equation for the line of best fit when the temperature outside is 86°F, is given by:

y = 0.004x²- 0.1243x + 84.028

when x = 55%, the heat index can be calculated as follows;

Amir's average speed for the whole journey was 51 km/h.

We have,

Let the total distance between Town A and Town B be D.

According to the problem,

Amir traveled 1/5 of the journey in the first two hours, which means he covered a distance of D/5 in 2 hours.

The remaining distance is 4D/5.

He then traveled 1/3 of the remaining journey in the next one hour, which means he covered a distance.

= (1/3) × (4D/5)

= 4D/15 in the next hour.

Therefore, the remaining distance.

= 4D/5 - 4D/15

= 8D/15.

It took him another 2 hours to cover the remaining distance of 136 km, so we have:

8D/15 = 136 km

Solving for D.

D = (136 km)×(15/8)

= 255 km

Therefore,

The total distance between Town A and Town B is 255 km.

The total time Amir took for the journey is 2 + 1 + 2 = 5 hours.

His average speed for the whole journey.

Three ordered pairs that could represent the location of another vertex of the square are (7, 2), (-5, 2), (1, 8).

To find the possible locations of the other vertices of the square, we need to determine the distance from point K to any other vertex of the square. Since the perimeter of the square is 20 units, each side of the square has a length of 20/4 = 5 units.

One way to find the other vertices is to draw a circle with center at K and radius 5 units, and then look for points on the circle that have integer coordinates. Alternatively, we can use the distance formula to calculate the distance from K to another point (x, y), which must be 5 units, and then solve for y in terms of x.

Using the distance formula, we get:

[tex]\sqrt{(x-1)^{2} +(y-1)^{2} }[/tex] = 5

Simplifying and squaring both sides, we get:

(x-1)^2 + (y-2)^2 = 25

Expanding the left side and simplifying, we get:

[tex]x^{2}[/tex] - 2x + [tex]y^{2}[/tex] - 4y + 20 = 0

Completing the square for x and y, we get:

[tex](x-1)^{2}[/tex]  + [tex](y-1)^{2}[/tex]  = [tex]6^{2}[/tex]

This is the equation of a circle with center at (1, 2) and radius 6 units. Any point on this circle that has integer coordinates could be a vertex of the square, since it will be exactly 5 units away from K.

Using this method, we can find several possible locations of the other vertices of the square. Three of them are:

Answer:

(10, 5π/3)

Step-by-step explanation:

To convert rectangular coordinates (5, -5√3) to polar form, we can use the following formulas:

r = √(x^2 + y^2)

θ = arctan(y/x)

Substituting the given values, we get:

r = √(5^2 + (-5√3)^2) = √(25 + 75) = √100 = 10

θ = arctan((-5√3)/5) = arctan(-√3) = -π/3

Note that the value of θ is in the fourth quadrant, which corresponds to a negative angle. However, we need to express the angle θ in the range 0 ≤ θ < 2π. To do this, we can add 2π to the angle if it is negative:

θ = -π/3 + 2π = (5π/3)

Therefore, the rectangular coordinates (5, -5√3) in polar form are (10, 5π/3).

Answer: 5

Step-by-step explanation:

Since x is directly related to the square of y, we can write the equation:

x = ky^2

where k is a constant of proportionality. We can solve for k using the given values of x and y:

16 = k(2^2) -> 16 = 4k -> k = 4

Now that we know k, we can use it to find y when x = 100:

100 = 4y^2 -> 25 = y^2 -> y = ±5

Since y cannot be negative, the only possible value of y is 5. Therefore, when x = 100, y could be 5.

Answer:

One possible value of y when x = 100 is y = 5.

Step-by-step explanation:

Using the direct variation formula, we know that x = ky^2, where k is a constant. Given that x = 16 and y = 2, we can solve for k:

16 = k(2)^2

k = 4

Now we can use this value of k to find y when x = 100:

100 = 4y^2

y^2 = 25

y = 5 or -5 (since the question only asks for one possible value, we can choose either solution)

Therefore, one possible value of y when x = 100 is y = 5.

The resulting z-test statistic is 0.44, indicating that the evidence is not significant enough to reject the null hypothesis that the probability of heads is equal to 0.5.

The problem we are trying to solve is to determine if the sample proportion of heads obtained from spinning a penny 300 times (134 heads) is significant evidence against equal probabilities of heads and tails. To do this, we will be testing the null hypothesis H0: p = 0.5, which states that the probability of getting heads is equal to 0.5.

We can calculate the z-test statistic using the formula z = (sample proportion - hypothesized proportion) / (standard error). In this case, the z-test statistic is z = (0.444 - 0.5) / (√(0.5 * 0.5 / 300)) = -0.86. This means that the sample proportion of heads is 0.86 standard errors away from the hypothesized proportion of 0.5.

Therefore, the resulting z-test statistic is 0.44, indicating that the evidence is not significant enough to reject the null hypothesis that the probability of heads is equal to 0.5.
