Find the geometric mean between 20 and 5

The claim supported by the confidence interval is as follows:

The southern frogs are likely to have a greater mean number of croaks per hour than the northern frogs.

The 95% confidence interval for the difference(southern - northern) is given by:

(7.1, 8.1)

Since the entire confidence interval is above 0, the claim supported by it is as follows:

The southern frogs are likely to have a greater mean number of croaks per hour than the northern frogs.

Answer:

448

Step-by-step explanation:

This is  a proportion question. Keep the heights on one side of the proportion and the shadow length on the other.

height ratio  shadow ratio

40 cm / x = 25 / 280             Cross multiply

25x = 40 * 280                      Combine

25x = 11200                            Divide by 25

x = 11200/25

x = 448 cm

The height of the corn plant is 448 cm

Using proportions, it is found that the original angle is of 2250º. The co-terminal angle is of 90º, which has sine equals to 1.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The proportion considered in this problem is that 2pi  is equivalent to 360º and we want to find the equivalent angle to 200pi/16, hence the rule of three is given by:

2 pi - 360º

200pi/16 - x º

Applying cross multiplication:

[tex]x = \frac{1}{2\pi} \times 360 \times \frac{200\pi}{16}[/tex]

[tex]x = 2250^\circ[/tex]

The original angle is of 2250º.

To find the co-terminal angle, we find the remainder of the division of 2250 by 360, hence it is of 90º, which has sine equals to 1.

Answer:

(10 + q) ÷ 5

Explanation:

the sum of  10 and a number q is 10 + q

one fifth is dividing by 5

so (10+q) ÷ 5

Answer:

x = 6 cm

Step-by-step explanation:

We can write equations for length and width using the information given:

length = 2 + x

width = 2x - 5

Area = (length)(width) = 56

Area = (2 + x)(2x - 5) = 4x - 10 + 2x² - 5x

Simplifying:

Area = 2x² - x - 10 = 56

2x² - x - 66 = 0

Factoring:

(2x + 11)(x - 6) = 0

x = 6, -11/2

We choose the positive number: x = 6 cm

To check, plug in 6 for x:

Area = (2 + x)(2x - 5) = 56

(2 + 6)(12 - 5) = 56

(8 × 7) = 56

56 = 56

Solving steps:

Question:5 boys and 4 girls are randomly arranged to sit in a row. find the probability that all girls sit together.

Find:the probability that all girls sit together.

Solution: 5 boys and 4 girls, 9 kids in all, can be seated in a row in 9! ways. In order to find the number of ways, where the 4 girls are seated together, we place them in an imaginary group Z, so that they are not separated in the seating arrangements. Now we have 6 entities, namely 5 boys and one group of girls, and the number of ways of their seating is 6!. For each of these 6! ways, the 4 girls can be seated within the group Z in 4! ways. So the number of ways in which the 4 girls are seated together, is 6!/4!.

So the probability, as requested, is (6!4!)/9! = 24/(7x8x9) = 1/21

Step-by-step explanation:

Answer:

48 feet.

step-by-step explanation:

using Pythagoras theorem:

a² + b² = c²

h² + 55² = 73²

h² = 73² - 55²

h² = 5329-3025

h² = 2304

h = √2304

h = 48

Answer:

x = 48 ft

Step-by-step explanation:

Pythagoras' Theorem: a² + b² = c²

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

Given:

Substitute the given values into the formula and solve for x:

⇒ x² + 55² = 73²

⇒ x² + 3025 = 5329

⇒ x² = 5329 - 3025

⇒ x² = 2304

⇒ x = ±√2304

⇒ x = ±48

Since distance is positive, x = 48 ft

Answer:

38 degrees

Step-by-step explanation:

To get the answer, we need to subtract the first angle from the second angle:

84-46=38

The minute hand turned 38 degrees from its first to second position.

How to check the answer? Use inverse operations.

46+38=84

By solving the quadratic equation using completing the square method we got that Penelope should have added 4 to both sides instead of adding 1.

Any equation of the form [tex]ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called quadratic equation .

Given work of Penelope is

[tex]$$\begin{aligned}&f(x)=4 x^{2}+8 x+1 \\&-1=4 x^{2}+8 x \\&-1=4\left(x^{2}+2 x\right) \\&-1+1=4\left(x^{2}+2 x+1\right) \\&0=4(x+2)^{2} \\&0=(x+2)^{2} \\&0=x+2 \\&-2=x\end{aligned}$$[/tex]

Now we can see that Penelope determined the solutions of the quadratic function by completing the square. so he must have been done as following

[tex]$$\begin{aligned}&f(x)=4 x^{2}+8 x+1 \\&-1=4 x^{2}+8 x \\&-1=4\left(x^{2}+2 x\right) \\&-1+4=4\left(x^{2}+2 x+1\right) \\&3=4(x+2)^{2} \\&\frac{3}{4} =x+2)^{2} \\&\frac{\pm\sqrt3}{2} =x+2 \\&\frac{-2\pm\sqrt3}{2} =x\end{aligned}$$[/tex]

By solving the quadratic equation using completing the square method we got that Penelope should have added 4 to both sides instead of adding 1.
