Hello! :)

The answer is probably from changing first to decimals by dividing by 100: 90 and 30 become .9 and .3.

Then, multiply the two: .9 x .3 = .27

Finally, you multiply .27 by 100 = 27

Add the percentage sign: 27%

So there is a 27% chance that it will rain and the baseball game is postponed.

Very unlikely, I know. ;D

Hope this helped and I hope I answered in time!

The probability it will rain tomorrow and the baseball game is postponed is 0.93 .

A probability is a number that reflects the chance or likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.

According to classical definition of probability, a random experiment consists of a set of possible outcomes and each set of possible outcomes is equally likely to occur in the course of the event.

It is given that there is a 90% chance of rain tomorrow and a 30% chance that the baseball game is postpone.

Let A be the probability that there is a chance of rain tomorrow and B be the probability that the baseball game is postpone.

P(A) = 90% = 0.9 and P(B) = 30% = 0.3 and P(A∩B) = (0.9*0.3) = 0.27 .

The probability it will rain tomorrow and the baseball game is postponed is given by P(A∪B) .

By formula,

⇒ P(A∪B) = P(A) + P(B) - P(A∩B)

⇒ P(A∪B) = 0.9 + 0.3 - 0.27

∴  P(A∪B) = 0.93 .

Therefore, the probability it will rain tomorrow and the baseball game is postponed is 0.93 .

Step-by-step explanation:

Find the common ratio r of the geometric sequence then multiply a term by r to obtain the next term

r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{6}{-36}[/tex] = - [tex]\frac{1}{6}[/tex]

The next 3 terms are

[tex]\frac{1}{6}[/tex] × - [tex]\frac{1}{6}[/tex] = - [tex]\frac{1}{36}[/tex]

- [tex]\frac{1}{36}[/tex] × - [tex]\frac{1}{6}[/tex] = [tex]\frac{1}{216}[/tex]

[tex]\frac{1}{216}[/tex] × - [tex]\frac{1}{6}[/tex] = - [tex]\frac{1}{1296}[/tex]

Answer:

J. [tex]-\frac{1}{36}[/tex], [tex]\frac{1}{216}[/tex], [tex]-\frac{1}{1296}[/tex]

Step-by-step explanation:

We are given the following geometric sequence and we are to find its 8th term:

[tex]-36, 6, -1, \frac{1}{6},...[/tex]

Here [tex]a_1=-36[/tex] and common ratio [tex](r) = \frac{-1}{6}=\frac{-1}{6}[/tex].

The formula we will use to find the next three terms is:

nth term = [tex]a_1 \times r^{(n-1)}[/tex]

5th term = [tex]-36 \times \frac{-1}{6}^{(5-1)}[/tex]  = [tex]-\frac{1}{36}[/tex]

6th term = [tex]-36 \times \frac{-1}{6}^{(6-1)}[/tex]  = [tex]\frac{1}{216}[/tex]

7th term = [tex]-36 \times \frac{-1}{6}^{(7-1)}[/tex]  = [tex]-\frac{1}{1296}[/tex]

So, The roots are [tex]x= \frac{1+\sqrt{5}i}{2} \,\, and \,\,x= \frac{1-\sqrt{5}i}{2}[/tex]

Step-by-step explanation:

[tex]4x^2 + 5x + 2 = 2x^2 + 7x - 1[/tex]

We need to solve the equation to find the roots using quadratic formula.

The quadratic formula is:

[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

Rearranging the above equation:

[tex]4x^2 -2x^2+ 5x-7x + 2+1 =0[/tex]

[tex]2x^2 -2x + 3 =0[/tex]

Where a =2 , b=-2 and c =3 Putting values in quadratic equation and solving:

[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{-(-2)\pm\sqrt{(-2)^2-4(2)(3)}}{2(2)}\\x=\frac{2\pm\sqrt{4-24}}{4}\\x=\frac{2\pm\sqrt{-20}}{4}\\\sqrt{-20} \,\,can\,\,be\,\, written\,\, as\,\, 2\sqrt{-5}\\ x=\frac{2\pm2\sqrt{-5}}{4}\\x=\frac{2+2\sqrt{-5}}{4} \,\, and \,\, x=\frac{2-2\sqrt{-5}}{4}\\x=\frac{2(1+\sqrt{-5})}{4} \,\, and \,\, x=\frac{2(1-\sqrt{-5})}{4}\\ x=\frac{1+\sqrt{-5}}{2} \,\, and \,\, x=\frac{1-\sqrt{-5}}{2}\\As \,\,we\,\, know\,\, \sqrt{-1} = i \\[/tex]

[tex]x= \frac{1+\sqrt{5}i}{2} \,\, and \,\,x= \frac{1-\sqrt{5}i}{2}[/tex]

So, The roots are [tex]x= \frac{1+\sqrt{5}i}{2} \,\, and \,\,x= \frac{1-\sqrt{5}i}{2}[/tex]

Step-by-step explanation:

A basket contains 14 white eggs, 15 brown eggs, and 11 lemons. The exact probability that Taylor picks an egg from the basket is;

(14+15)/(14+15+11) = 29/40

Answer:

The exact probability that Taylor picks an egg from the basket is 0.725

Step-by-step explanation:

A basket contains 14 white eggs, 15 brown eggs and 11 lemons.

Total number of items in the basket [tex]=14+15+11= 40[/tex]

Total number of eggs in the basket [tex]=14+15= 29[/tex]

Area of ΔEDF = 4.5 in²

Answer:

24 π square inches

Step-by-step explanation:

The area of a circule is give by the formula A = π r²

Since we have a angle of 60 degrees, that represent 1/6th of the whole area (60 / 360 degrees).

A circle = π * 12² = 144 π square inches

Area of the portion representing 60 degrees of the circle, can easily be calculated with a cross-multiplication:

[tex]\frac{x}{144\pi } = \frac{60}{360}[/tex]

x = 144 π / 6 = 24 π square inches

Answer:

The larger model’s volume is 3 times greater than the volume of the smaller model

Step-by-step explanation:

we know that

The volume of a pyramid is equal to

[tex]V=\frac{1}{3}Bh[/tex]

where

B is the area of the base of pyramid

h is the height of the pyramid

Find the volume of the smaller model

we have

[tex]h=10\ cm[/tex]

substitute

[tex]V=\frac{1}{3}B(10)[/tex]

[tex]V=\frac{10}{3}B\ cm^{3}[/tex]

Find the volume of the larger model

we have

[tex]h=30\ cm[/tex]

substitute

[tex]V=\frac{1}{3}B(30)[/tex]

[tex]V=\frac{30}{3}B=10B\ cm^{3}[/tex]

To find how many times greater than the smaller model is the larger model’s volume, divide the volume of the larger model by the volume of the smaller model

so

[tex]10B/(\frac{10}{3}B)=3[/tex]

The larger model’s volume is 3 times greater than the volume of the smaller model

To determine the numerator of a fraction that simplifies to 36 with a denominator of 6x^5, you solve the equation Numerator/6x^5 = 36 by multiplying both sides by 6x^5, resulting in a numerator of 216x^5.

To find the numerator of a fraction that reduces to 36 with a denominator of 6x^5, we set up an equation to represent the fraction in its simplest form.

We know that when we divide the numerator by the denominator, the result is 36. Therefore, the equation to solve is Numerator/6x^5 = 36.

Multiplying both sides of the equation by 6x^5 will isolate the numerator on one side.

The calculation becomes:

Numerator = 36 × 6x^5

Next, we carry out the multiplication to find:

Numerator = 216x^5

This means that the numerator of the original fraction is 216x^5.

Answer:

a. 38.3

b. 41.0

Step-by-step explanation:

We have been given the linear model;

a = 0.25t + 29

where a represents the median age of females in the United States and t the number of years since 1970

a.

We are required to predict the median age of females in 2007. The first step is to determine the number of years from 1970 to 2007 by finding the difference;

2007 - 1970 = 37

2007 is  thus 37 years after 1970.

The next step is to substitute t = 37 in the given linear model;

a = 0.25( 37) + 29 = 38.25

b.

We are required to predict the median age of females in 2018. The first step is to determine the number of years from 1970 to 2018 by finding the difference;

2018 - 1970 = 48

2018 is thus 48 years after 1970

The next step is to substitute t = 48 in the given linear model;

a = 0.25( 48) + 29 = 41

To calculate the length of CE, use the properties of similar triangles. Use the same proportion to calculate the length of DE. To find the area of the quadrilateral BDEC, calculate the area of the triangle CDE and subtract it from the area of ABCD.

To calculate the length of CE, we need to use the properties of similar triangles. Since ABC and AED are similar, we can set up the proportion AB/AC = AD/AE. We know that AB = 5cm and AC = 10cm, and we need to solve for AE. Rearranging the proportion, we get AE = AD * AC / AB. Plugging in the values, AE = 6cm.

To calculate the length of DE, we can use the same proportion from above, but this time solving for DE. Rearranging the proportion, we get DE = AD * AC / AB. Plugging in the values, DE = 3cm.

The area of triangle ABD is given as 36cm. To calculate the area of the quadrilateral BDEC, we need to find the area of the triangle CDE and subtract it from the area of the quadrilateral ABCD. Since triangles CDE and ABC share the same height, we can use the ratios of their bases to calculate the area of CDE. The ratio of CE to CB is 6/10, so the ratio of the areas of CDE to ABC is (6/10)^2 = 0.36. Therefore, the area of CDE is 0.36 times the area of ABC, or 0.36 * 36cm = 12.96cm.
