What is 4. 5 as a fraction?.

Alya put an average amount of 10.5g of the mix in each bowl.

Define average.

In math and statistics, the arithmetic mean or arithmetic average, or just the mean or the average, is the sum of a collection of numbers divided by the count of numbers in the collection.

The average is defined as the mean value, which is equal to the ratio of the sum of a given set of values to the total number of values present in the set.

Solution Explained:

Given in question,

Amount of pretzels = 10.2g

Amount of nack mix = 21.3g

When mixed,

The amount of the combined mix = 10.2 + 21.3 = 31.5g

So, if there are 3 bowls and Alya puts an equal amount into each one, we get

Amount of mix in each bowl = 31.5/3 = 10.5g

The area of the triangle when the height is 12 cm would be 414 cm².

The area of the triangle is half the product of its base and height.

A = (1/2)bh

Given that the area A of a triangle whose base is b 3 cm less than six times the height h.

Consider h be the height of the triangle. With this the base may be represented as; 6h - 3.

Therefore,

A = (1/2)bh

A =  (1/2)(6h - 3)h

Now to the equation the value of h, 

  A = (1/2)((6)(12 cm) - 3)(12 cm)

A = 414 cm²

Type I error means rejecting the true null hypothesis and Type II error means failing to reject a false null hypothesis.

A Type I error occurs in hypothesis testing when one rejects the null hypothesis and the null hypothesis is true.

To reject the null hypothesis, statisticians conduct hypothesis testing. However, the process is always accompanied by the possibility of making a mistake. These are referred to as hypothesis testing errors.

Type I and Type II errors are the two mutually exclusive errors in hypothesis testing. Type II errors occur when a statistician fails to reject a false null hypothesis, whereas Type I errors occur when a statistician correctly rejects a genuine null hypothesis.

In the given question, type I error means rejecting the true null hypothesis i.e. h0: the person is free of disease but we conclude that the person has the disease. This is called a false positive. ha: Type II error means failing to reject a false null hypothesis.

The following systems of equations can be used to find the number of pounds of zucchini that were solds z + c = 108 and 150.32 = 1.69z + 0.99c

A farmer sold 108 pounds of produce

The produce that consisted of z pounds of zucchini and c pounds of cucumbers.

z + c = 108

The farmer sold the zucchini for $1.69 per pound and the cucumbers for $0.99 per pound

He collected a total of $150.32.

Money collected by zucchimi = 1.69 x z = 1.69z

Money collected by cucumbers = 0.99 x c = 0.99c

Total money collected = money collected by zucchini + money collected by cucumbers

150.32 = 1.69z + 0.99c

Therefore, the system of equations is z + c = 108 and 150.32 = 1.69z + 0.99c

A scale is used to give context to the user about the size of the area that map covers. It is made by converting real-life measurements into physical measurements for quick calculations.

Brenda measured the middle school and made a scale drawing.

The actual length of the gym = 90 ft.

The length she used in her drawing = 18 inches.

So we will now find the scale used for this drawing,

18 inches = 90 ft.

(c) is the correct option. When we subtract w₂ from w₁, we get (2 - 3i).

According to our question, we came to know the values of w₁ and w₂ which are written below:
w₁ = -3i
w₂ = -2

In order to subtract w₂ from w₁, we need to arrange the expression as below:

w₁ - w₂ = -3i - (-2)
Upon opening the bracket, minus(-) will be multiplied by (-2) and it becomes +2.  ∴ - x - = +

Hence,
w₁ - w₂ = -3i + 2

We cannot add -3i with 2 as 'i' referred to as 'iota' is an imaginary number that is used to express complex numbers. Its value is [tex]\sqrt{-1}[/tex]. So, our final solution will be.

How to find the intervals where a function is concave up and concave down?

In determining intervals where a function is concave upward or concave downward, you first find domain values where f″(x) = 0 or f″(x) does not exist. Then test all intervals around these values in the second derivative of the function. If f″(x) changes sign, then ( x, f(x)) is a point of inflection of the function.

g(x) =5x^3+8x

g'(x) = 15x^2+8

g''(x)= 30x

g''(x)= 0

The probability that the first card is an ace and the second card is a face card is 1.78% and 12/52 respectively.

What is the probability of cards?

Probability is measured by counting and using basic math, such as addition and division. For example, you can multiply the number of spades in a complete deck (13) by the total number of cards in the deck (52) to get the probability of drawing a spade at random: 13 in 52, or 25%.

If you are dealt two cards successively from a standard 52-card deck, find the probability of getting an ace card on the first card and a face on the second.

you want to draw an ace. There are 4 aces out of the 52 cards in the deck so the probability of drawing an ace = 4/52.

So, the combined probability [tex](\frac{12}{52}) . (\frac{4}{52}) = (\frac{3}{13}) . (\frac{1}{13}) = (\frac{3}{169})[/tex]

= 1.78%.

The probability of a face card on the second draw = 12/52 because there are 12 face cards (J, Q, K x 4 of each) and 52 cards in the deck.

Hence, the probability that the first card is an ace and the second card is a face card is 1.78% and 12/52 respectively.

Area of the triangle = [tex]\sqrt{(s(s - a) (s - b) (s - c)) }[/tex]

The semi-perimeter of the triangle, s = (a + b + c)/2

Let the triangle is ABC,

and AB = 3x - 1, BC = 4x + 1 and AC = 3x.

       Perimeter = 70

       AB + BC + AC = 70

      3x-1 + 4x + 1 +3x = 70

       10x = 70

          x = 7

AB = a = 3x - 1 = 20

BC = b = 4x + 1 = 29

AC = c = 3x = 21

Now semi-perimeter = s = 70/2

                                     s = 35
