It costs $0.49 for each avocado and $0.36 for each tomato.

Step-by-step explanation:

This is a system of equations problem.

Let x represent the avocados and y represent tomatoes:

4x + 5y = 3.76  <--- scenario 1

6x + 3y = 4.02 <---- scenario 2

If we graph these out on a graphing calculator, the lines will intersept at point (0.49,0.36)

The x coordinate represents how much it costs for each avacado and the y coordinate represents how much it costs for each tomato

Answer: If Lin sells b boxes of cookies, she will earn 3.75b dollars. Therefore, the inequality that will be true whenever Lin makes her goal is:

3.75b > 30

This inequality can be read as "the total amount of money Lin earns selling cookies is greater than $30."

Step-by-step explanation:

In order to plot the region enclosed by the given graphs we have to find the intersection points of all the 3 graphs taking 2 at a time

so finding intersection point of the y=4/x and y=16x

4/x=16x

=> [tex]x^{2}[/tex] = 1/4

=> x = 1/2 as x>0

and y=16x

=> y =8

now finding intersection point of y=4/x and y=1/16x

=> 4/x =x/16

=> [tex]x^{2}[/tex] = 64

=> x = 8 as x>0

and y= 4/x

=> y=1/2

now finding intersection point of y=16x and y=1/16x

the intersection point of both line is x=0

so y=16x

=> y=0

so we will get the intersection point of all the lines now after plotting all the points below we will get the graph as attached below.

Answer: 10 cm

Step-by-step explanation:

Given, length=8cm

breadth=6 cm

Pythagoras theorem states that sum of square of base and square of perpendicular height is equal to square of hypotnyse.

Thus, we can write:

Considering, base=length=8cm

Perpendicular=breadth=6cm

Therefore, length of diagonal =√(length∧2+breadth∧2)

                                                 =√(8∧2+6∧2) cm

                                                = 10 cm

Therefore the length of diagonal = 10cm.

The number of standard deviations from the t-mean distribution is equal to a t-score. The test statistic used in t-tests and regression testing is the t-score. When the data follow a t-distribution, it may also be used to represent how distant an observation is from the mean.

The t-score formula is written as follows:t=¯¯¯x−μS√n t = x ¯ − μ S n , where ¯¯¯x, is the sample mean, is the population mean, S n is the sample size, and x is the standard deviation of the sample. Square root n must be included in the formula.

using tables of t distribution we have

t-score for 99.8%

Confidence Interval (alpha) =1-0.998=0.002

To solve this problem, we can use the Pythagorean theorem to find the height of the balloon. In particular, we can consider the right triangle formed by the stake, the top of the balloon, and the part of the string that is attached to the stake.

[asy]

unitsize(2 cm);

pair A, B, C, D, E;

A = (0,0);

B = (0,15);

C = extension(A,B,A+(1,0),B+(1,0));

D = extension(A,C,A+(0,1),C+(0,1));

E = extension(B,D,B+(0,-1),D+(0,-1));

draw(A--B--C--cycle);

draw(A--D--E--cycle);

draw(rightanglemark(A,D,C,2));

label("$A$", A, S);

label("$B$", B, N);

label("$C$", C, E);

label("$D$", D, E);

label("$E$", E, W);

[/asy]

Let $a$ be the distance from the stake to the top of the balloon, $b$ be the height of the balloon, and $c$ be the length of the string. We know that $a = 15$ feet and $c = 15$ feet, so we can use the Pythagorean theorem to find $b$:

$a^2 + b^2 = c^2$

$15^2 + b^2 = 15^2$

$225 + b^2 = 225$

$b^2 = 0$

$b = \sqrt{0} = 0$ feet

Therefore, the height of the balloon is 0 feet. This is because the balloon has been pulled up by the wind so that its top is directly above the stake, and therefore its height is 0 feet.

Answer:

Step-by-step explanation:

There are just two triangles stuck together , here.  Don't let that throw you off your game :DD  

solve for a

then b

for a it's  180 = 2*36 +a   ( b/c of the red marks , again)

180 = 72 +a

180-72 =a

108 = a

Now solve for b

180 = 2b + 42  (red marks tell us this formula works,  again)

180-42 = 2b

138 =2b

138/2 =b

69 = b

The positive integers that would make (3²)ⁿ greater than 39 are any positive integers greater than 1.

An integer means the number zero (0), a positive natural number or a negative integer with a minus sign (−1, −2, −3, etc.).

To see this, we can simply plug in different values for the positive integer and see when(3²)ⁿ becomes greater than 39.

If we plug in 1, we get (3²)ⁿ = 9, which is not greater than 39.

If we plug in 2, we get (3²)ⁿ = 81, which is greater than 39.

Therefore, any positive integer greater than 1 would make (3²)ⁿ greater than 39.

Step-by-step explanation:

The average number of children in a family under the age of 1818 is 0.76, which is the predicted value of this distribution.

The product of each potential result and its associated probability yields the anticipated value of a probability distribution. The probable outcomes in this scenario are 0, 1, 2, 3, & 4 minors, with the associated probability shown in the table.

We may add the products of each result and its probability to determine the estimated return of this distribution:

Expected value = (0)(0.58) + (1)(0.18) + (2)(0.16) + (3)(0.06) + (4)(0.02)

= 0 + 0.18 + 0.32 + 0.18 + 0.08

2ab is the area of the greatest rectangle that can be inscribed in an ecllipse [tex]\frac{x^2}{a^2} + \frac{x^2}{b^2} = 1[/tex].

The reactangle with the greatest area that can be inscribed in an ecllipse is symmetry with respect to x axis .

we know that (a cos θ ,bsin θ) is the general point on the ecllipse so the others points is (- a cos θ ,bsin θ) , (a cos θ ,-bsin θ)  and (-a cos θ ,- bsin θ)

so the length of the rectangle is 2a cos θ  and the breadth of the rectangle is 2b sin θ

to area of rectangle = length * breadth

=> 2a cos θ  * 2b sin θ

=>4ab sin θ *cos θ

=> 4ab sin 2θ

so area of rectangle (A) = 4ab sin 2θ   -----(i)

so get the maximum area dA/dθ =0

=> 4ab *2 cos 2θ =0

=> 8ab cos 2θ=0

=> cos 2θ =0

=> 2θ = π/2

=> θ =π/4

putting the value of θ in equation (i) we get

A = 4ab cos π/4 *sin π/4

A = 4ab *[tex]\frac{1}{\sqrt{2} }[/tex]  *[tex]\frac{1}{\sqrt{2} }[/tex]

In order to estimate the mean height of all bears in the Smokies within 4 inches of the actual height with a 99% confidence level, you would need a sample size of 25 bears.

You must calculate the sample size using the formula below in order to estimate the mean bear height in the Smokies within 4 inches of the actual height at a 99% confidence level:

n = [tex](\frac{2 X SD}{E})^2[/tex]

Where,

n = sample size

SD = standard deviation of the population (which you have estimated to be 10 inches)

E = margin of error (which you want to be 4 inches)

Putting these values into the formula, we get:

n = [tex](\frac{2 X 10}{4})^2[/tex]

= 25

In order to estimate the mean height of all bears in the Smokies within 4 inches of the actual height with a 99% confidence level, you would need a sample size of 25 bears.

It's important to note that this is only a rough estimate, and the exact sample size may change depending on the population's real characteristics and the level of precision you require.

When n is large the distribution of the sample means will approach a normal distribution.

The central limit theorem (CLT) is a statistical theory that predicts that given a large enough sample size from a population with a certain level of variation, the mean of all the samples from that population will be close to the population mean.

To put it another way, the central limit theorem predicts with absolute certainty the form of the distribution of means when we take repeated samples from a certain population. In particular, the distribution of means derived from repeated sampling will tend toward normality as sample sizes increase.

In other words, when n is large, the distribution of the sample means will resemble a normal distribution if we continually pick independent, random samples of size n from any population.

Liza will pass Ralph after 5 hours, and they each will have traveled 325 miles.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The situation is modeled by this system,

⇒ y = 60x + 25

⇒ y = 65x

Where, x is the number of hour after Liza leaves and y is the distance each will travel.

Now,

Since, The situation is modeled by this system,

⇒ y = 60x + 25

⇒ y = 65x

To equate both equation, we get;

⇒ 65x = 60x + 25

⇒ 5x = 25

⇒ x = 5

Thus, Liza will pass Ralph after 5 hours.

And, The distance will they each have traveled is,

⇒ y = 60x + 25

⇒ y = 60 × 5 + 25

⇒ y = 300 + 25

⇒ y = 325 miles

Thus, They each will have traveled 325 miles.
