Answer:

B. Reject the claim that the proportion of Americans that have seen a UFO is equal to 2 in a thousand when that proportion is actually 2 in a thousand

Step-by-step explanation:

The type I error is rejection of true null hypothesis.

In the given scenario our hypothesis are

Null hypothesis: The proportion of Americans that have seen a UFO is equal to 2 in a thousand.

Alternative hypothesis: The proportion of Americans that have seen a UFO is less than 2 in a thousand.

Type I error is the rejection of true null hypothesis so, in this case type I error is rejection of claim  that the proportion of Americans that have seen a UFO is equal to 2 in a thousand when that proportion is actually 2 in a thousand.

Answer:

D. 15 pounds

Step-by-step explanation:

35-20=15

The range of the data that represents the number of pounds of trash collected by each teenager is 15.

The range is the difference between the Maximum value of the data set and the Minimum value of the dataset. Therefore, we can write the range as,

Range = Maximum value of the data set - Minimum value of the dataset

Given the data for the number of pounds of trash collected by each teenager as 26, 26, 21, 22, 20, 25, and 35.

Now, from the data, the Maximum value of the data set is 35 and the Minimum value of the dataset is 20. Therefore, we can write the range of the data set as,

Range = Maximum value of the data set - Minimum value of the dataset

          = 35 - 20

          = 15

Hence, the range of the data that represents the number of pounds of trash collected by each teenager is 15.

here's my work

An expression is defined as a set of numbers, variables, and mathematical operations. The solution for the expression  39 ÷ (2 + 1) - 2 × (4 + 1) is 3.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Using the rule of BODMAS the solution for the expression  39 ÷ (2 + 1) - 2 × (4 + 1) is,

39 ÷ (2 + 1) - 2 × (4 + 1)

=  39 ÷ (3) - 2 × (5)

= 13 - 2  × (5)

= 13 - 10

= 3

Hence, the solution for the expression  39 ÷ (2 + 1) - 2 × (4 + 1) is 3.

Answer:

it is 90 degrees

Step-by-step explanation:

All you have to do is add the sides that you know and triangles total is 180 so add 32+58 and u get 90 degrees then u will have to subtract 180 from 90 and it equals 90 which is your missing angle

Answer:

We can see that:

a₀ = 4

a₁ = 4/3

a₂ = 4/9.

We easily can see that the n-th therm of this will be:

aₙ = 4/3^n.

Now, the denominator increases as n increases, then for a really large n, aₙ will tend asymptotically to zero. This means that this summation converges.

We can write this summation as:

4*∑(1/3)^n.

The sum for the first N-th therms is:

We know that for a summation:

1 + r + r^2 + r^3 + ... + r^N = (1 - r^(N + 1))/(1 - r)

4 + 4*(1/3) + 4*(1/3)^2 + ... + 4*(1/3)^N = 4*( 1 - (1/3)^(N + 1))/(1 - (1/3))

Now, for the complete sum we have that:

n = {0, 1, 2, ...}

We know that for a summation:

∑a*r^n

with n = {0, 1, ...}

the sum is = a/(1 + r).

in this case we have:

a = 4, r = 1/3.

Then the sum is:

S = 4/(1 - 1/3) = 4/(2/3) = 3*2 = 6

Answer:

No, The answer is 20. Remember area of triangle equals 1/2bh (or half of base and height multiplied.)

The area of triangle that has a base length of 10 inches and a height of 4 inches is 20 square inches.

The area of a triangle is one half the product of its base multiplied by height. Mathematically -

Area [Δ] = 1/2 x base x height

Given is a triangle (Δ) has a base length of 10 inches and a height of 4 inches.

We can write -

Base Length [B] = 10 inches

Height of triangle [H] = 4 inches

Area of triangle (Δ) = 1/2 x B x H

A(Δ) = 1/2 x B x H

A(Δ) = 1/2 x 10 x 4

A(Δ) = 20 square inches

Therefore, the area of triangle that has a base length of 10 inches and a height of 4 inches is 20 square inches.

Answer:

A= 12.57 inches squared

Step-by-step explanation:

The formula for the area of a circle is A=πr2. Substitute 2 for r, square it, and multiply it by pi (3.14.) The answer is 12.57 inches squared.

Answer:

[tex]\boxed {\tt a\approx 12.57 \ in^2}[/tex]

Step-by-step explanation:

The area of a circle can be found using the following formula.

[tex]a= \pi r^2[/tex]

The radius of the circle is 2 inches.

[tex]r= 2 \ in[/tex]

Substitute the value into the formula.

[tex]a=\pi ( 2 \ in)^2[/tex]

Evaluate the exponent.

[tex]a= \pi(4 \ in^2)[/tex]

Multiply.

[tex]a=12.5663706 \ in^2[/tex]

Round to the nearest hundredth. The 6 in the thousandth place tells us to round the 6 to a 7.

[tex]a\approx12.57 \ in^2[/tex]

The area of the circle is about 12.57 square inches.

A literal equation is x^2 + 2y = 1 because it contains more then one distant variable while y = 4 doesn’t, it only contian y.

An equation represents equality of two or more mathematical expression.

When someone asks you to solve an equation, then they usually mean to find the values of the unknowns for which that equation would be true (the equality between expressions should hold true for those values).

A Solutions to an equation are those values of the variables involved in that equation for which the equation is true.

A literal equation is x^2 + 2y = 1 because it contains more then one distant variable while y = 4 doesn’t, it only contian y.

Therefore, y=4 is not a literal equation because it has y as the only variable that appears.
