Answer: 7/8

Step-by-step explanation:

Let the boy is letter B and the girl is letter G.

So the possible outcomes are as follows below

BBB, BBG, BGB, GBB, BGG, GBG, GGB, GGG

SO the number of possible outcomes is 8

The number of outcomes where is at least 1 girl ( triples where is 1 girl, 2 girls or all 3 children are the girls) is 7

So the probability, that family with 3 kids has at least 1 girl is

P(number of girls >=1)=  7/8

Answer:

y=4x-8

Step-by-step explanation:

First you must use the distributive property and get y-8=4x-16.

Then you have to add 8 on both sides so just y is left on the left side.

This will get you y=4x-8 in slope-intercept form.

Answer:

84%

Step-by-step explanation:

The probability that the selected player is a football player, P(F)=19%

The probability that the selected player is a basketball player, P(B)=79%

The probability that the selected player play both football and basketball,

[tex]P(B \cap F)=14\%[/tex]

We want to determine the probability that a randomly chosen athlete is either a football player or a basketball player, [tex]P(B \cup F)[/tex]

In probability theory

[tex]P(B \cup F)=P(B)+P(F)-P(B \cap F)\\=79\%+19\%-14\%\\=84\%[/tex]

The probability that a randomly chosen athlete is either a football player or a basketball player is 84%.

Answer:

Volume of cylinder = π/4 (the volume of the prism) or π/4 (4r²)(h) or πr²h (D)

The complete question related to this found on brainly (ID: 4049983 and 4265826) is stated below:

A cylinder fits inside a square prism as shown. For every cross section, the ratio of the area of the circle to the area of the square is or πr^2 or π/4. Since the area of the circle is π/4 the area of the square, the volume of the cylinder equals

A) π/2(the volume of the prism) or π/2 (2r)(h) or πrh.

B) π/2 (the volume of the prism) or π/2 (4r2)(h) or 2πrh.

C) π/4(the volume of the prism) or π/4 (2r)(h) or π/4(r2h).

D) π/4(the volume of the prism) or π/4 (4r2)(h) or πr2h.

See attachment for diagram

Step-by-step explanation:

Area of the cross section in the cylinder

Area of circle = πr²

Area of the cross section in the square prism

Area of square = (side length)²

Here the side length = diameter

Diameter = 2×radius = 2r

Area of square = (2r)² = 4r²

Ratio of area of circle to area of square = πr²/4r² = π/4

Area of circle/area of square = π/4

Area of circle = π/4 × area of square

Area of circle = π/4 × 4r²

Volume of cylinder = area of circle × height

Volume = πr² ×h = πr²h

Volume of square prism = area of square × height = (2r)²h = 4r²h

Ratio of volume of cylinder to volume of square prism = πr²h/4r²h = π/4

Volume of cylinder/volume of square prism = π/4

Volume of cylinder = π/4 × volume of square prism = π/4 × 4r²h

= πr²h

Therefore Volume of cylinder = π/4 (the volume of the prism) or π/4 (4r²)(h) or πr²h (D)

Answer:

(a) H₀: p = 0.11 vs. Hₐ: p > 0.11.

(b) A type I error occurs when we discard a true null hypothesis (H₀) and a type II error is made when we fail to discard a false null hypothesis (H₀).

Step-by-step explanation:

A college needs to know how many left-handed desks to place in the big lecture halls being constructed on its campus.

From past data, it is believed that 11% of all Americans are left-handed.

The college wants to know if the data provide enough evidence to show that students at this college have a higher percentage of left-handed people than the general American population.

(a)

The hypothesis can be defined as follows:

H₀: The percentage of left-handed people in the college is 11%, i.e. p = 0.11.

Hₐ: The percentage of left-handed people in the college is more than 11%, i.e. p > 0.11.

(b)

A type I error occurs when we discard a true null hypothesis (H₀) and a type II error is made when we fail to discard a false null hypothesis (H₀).

In this case, a type I error would be committed if it is concluded that the percentage of left-handed people in the college is more than 11% when in fact it is 11%.

And, a type II error would be committed if it is concluded that the percentage of left-handed people in the college is 11% when in fact it is more than 11%.

DE is secant on the circle below.

A secant line is a straight line that twice intersects a circle.

We have a diagram of circle.

As, Either a secant or a tangent will arise from the circle's junction.

A secant is a line that intersects a circle twice. The relationship between the circle and the line that intersects it is explained by this idea.

Again from the figure CA and CE intersect circle at B and D.

Answer:

The answer is

Step-by-step explanation:

Let n represent the number of children

Let c represent the number of candies

The above variation is written as

[tex]c = \frac{k}{n} [/tex]

when n = 12 c = 140

So we have

[tex]140 = \frac{k}{12} [/tex]

Cross multiply

That's

k = 1680

So the formula for the variation is

[tex]c = \frac{1680}{n} [/tex]

when n = 8

[tex]c = \frac{1680}{8} [/tex]

c = 210

Therefore there are 210 candies consumed when there are 8 children

Answer:

24 cubic feet.

Step-by-step explanation:

What we need to do here, is to find the volume of the aquarium.

The Aquarium is a rectangular prism.

The volume of a rectangular prism is length*width*height (we just multiply the dimensions together)

2*4*3=8*3=24

The volume of the aquarium is 24 cubic feet, and therefore 24 cubic feet of water is required to fill the tank.

Answer:

1). SUBTRACTION property of equality

2). MULTIPLICATION property of equality

Step-by-step explanation:

Step 2:

When we subtract the same number from both the sides of an equation it represents the subtraction property of equality.

[tex]\frac{x}{4}+5-(5)=23-(5)[/tex]

Here 5 has been subtracted from both the sides.

Therefore, SUBTRACTION property of equality was applied.

Step 4:

If the same number is multiplied to both the sides of an equation, multiplication property of equality is applied.

[tex]4\times \frac{x}{4}=4\times (18)[/tex]

Here 4 has been multiplied to both the sides.

Therefore, MULTIPLICATION property of equality was applied.

Answer:

[tex]V(n) = 575000(0.7)^{n}[/tex]

Step-by-step explanation:

The value of the machine after n years is given by an exponential function in the following format:

[tex]V(n) = V(0)(1-r)^{n}[/tex]

In which V(0) is the initial value and r is the yearly rate of depreciation, as a decimal.

A company buys a machine for $575,000 that depreciates at a rate of 30% per year.

This means, respectively, that: [tex]V(0) = 575000, r = 0.3[/tex]. So

[tex]V(n) = V(0)(1-r)^{n}[/tex]

[tex]V(n) = 575000(1-0.3)^{n}[/tex]

[tex]V(n) = 575000(0.7)^{n}[/tex]

Answer:

22 feet

Step-by-step explanation:

Change 15 feet into inches using the conversion

1 foot = 12 inches, thus

15 ft = 15 × 12 = 180 inches

scale factor = 180 ÷ 3.75 = 48

Thus the actual dimensions of the boat are 48 times the model.

actual length = 48 × 5.5 = 264 inches = 264 ÷ 12 = 22 feet

Find the partial derivatives indicated Assume the variables are restricted to a domain on which the function is defined. z=[tex]x^{8}[/tex]+[tex]3^{y}[/tex]+[tex]x^{y}[/tex]

a) Zx b) Zy

In differentiation, if y = axⁿ, y' = [tex]nax^{n-1} \ where \ n\ is\ a\ constant[/tex]. Applying this in question;

Given the function z = x⁸+[tex]3^{y}[/tex]+[tex]x^{y}[/tex]

[tex]Z_x = \frac{\delta z}{\delta x} = 8x^{7} + 0 + yx^{y-1} \\\frac{\delta z}{\delta x} = 8x^{7} + yx^{y-1} \\[/tex]

Note that y is treated as a constant since we are to differentiate only with respect to x.

For Zy;

[tex]Z_y = \frac{\delta z}{\delta y} =0+ 3^{y} ln3 + x^{y}lnx \\\frac{\delta z}{\delta y} = 3^{y} ln3 + x^{y}lnx } \\[/tex]

Here x is treated as a constant and differential of a constant is zero.

Answer:

A. Ryan conducted a survey where he asked about qualitative data.

Step-by-step explanation:

Surveys when carried out on people as the subjects are meant for the purpose of extracting some specific information from them. Observational studies involve close monitoring of the subject under evaluation. Quantitative data mainly deal with numbers and figures obtained from measurements or calculations. Qualitative data on the other hand is basically descriptive in nature and could sometimes be quite detailed.

Ryan's data collection would require a yes or no answer from the schools involved, and this information is descriptive or qualitative in nature. It also does not involve observation or close monitoring as he relies on the information provided by the school.

Measure of an arc = ( intercepted angle/ full circle) x circumference

4 ft =( intercepted angle/360) x (2 x 10 x pi)

4 = intercepted angle /360 x 62.8

Divide both sides by 62.8

4/62.8 = intercepted angle/360

Multiply both sides by 360

Intercepted angle = (4/62.8) x 360

Angle = 22.93 degrees

Answer:

22.9 degrees

Step-by-step explanation:

The degree measure (in radians) can be found using the following formula.

Θ=S/r

where S is the arc length and r is the radius.

We know the arc length is 4 feet and the radius is 10 feet. Substitute the values into the formula.

Θ= 4/10

Θ= 0.4

The measure is 0.4 radians.

Convert radians to degrees using the following formula.

Θ * 180/π

We know that Θ= 0.4 , so we can substitute it in.

0.4 * 180/π

0.4 * 57.2957795

22.9183118

Round to the nearest tenth. The 1 in the hundredth place tells us to leave the 9 in the tenth place.

22.9

The angle measure is about 22.9 degrees.
