Jahiem made about 3/2 cups of trail mix.

A ratio indicates the number of times one number contains another.

Given that, Jaheim made a bag of trail mix with 1/2 cup of almonds, 6/7 cup of apple slices, and 1/8 cup of pumpkin seeds.

The total amount of trail mix is:

1/2 cup of almonds + 6/7 cup of apple slices + 1/8 cup of pumpkin seeds

= 1/2 + 6/7 + 1/8

= (28 + 48 + 7)/56

= 83/56

≈ 3/2

Hence, Jahiem made about 3/2 cup of trail mix.

The value of the expression (x-4) minus -8x² - 8 is [tex]8x^{2}[/tex]+x+4.

According to the question,

We have the following information:

x - 4 minus -8x² - 8

Now, we will convert this into an expression only using mathematical signs. So, we have the following expression:

(x-4)-(-8x² - 8)

Now, we know that the multiplication of two negative integers gives us the positive results and the multiplication of one positive and one negative integer give us the negative results.

So, we have the following expression after multiplying -1 into the bracket :

x-4+8[tex]x^{2}[/tex]+8

[tex]8x^{2}[/tex]+x+4

Hence, the value of the expression (x-4) minus -8x² - 8 is [tex]8x^{2}[/tex]+x+4.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two expressions 3x + 5 and 14, which are separated by the 'equal' sign. a formula that expresses the connection between two expressions on either side of a sign. Typically, it has a single variable and an equal sign. Like this: 2x - 4 = 2. In the provided example, the variable x exists. A mathematical sentence with two equal sides and an equal sign is called an equation. An example of an equation is 4 + 6 = 10.

The percentage of women that have heights between 64 and 66 inches is 42.06%

The third quartile is 65.1875 inches

Part a

Given: mean=63.5 inches

std. deviation=2.5 inches

To find percentage: we calculate probability and convert to percentage

P(64<X<66) would mean

Z statistic=64-63.5/2.5=0.2

                 =66-63.5/2.5=1

From Z table, we find corresponding probability values.

Therefore, P(64<X<66)=P(0.2<Z<1)=0.84134-0.42074

                                                                     =0.4206

Thus percentage=0.4206*100

                           =42.06%

Part b

Finding the third quartile, Q3

Q3=mean+(0.675)*std. dev

Q3=63.5+(0.675*2.5)

=65.1875 inches

The probability that the ball selected from box b is white is 4/9.

The probability that the transferred ball was white given that the ball selected from box b was white is 1/2.

(a) Box a: 4red and 2 white balls

Box b: 1 red and 1 white balls

Case 1: Ball transferred from  Box a is White and then Ball chosen from Box b is White

Favorable Probability = Probability of chosen ball white in box a * Probability of chosen ball white from box 2

i.e. Favorable Probability = (2/6)*(2/3)

                                         = 4/18

Case 2: Ball transferred from Box a is Red and then Ball chosen from Box b is White

Favorable Probability = Probability of transferred ball is Red in box a * Probability of chosen ball white from box b

i.e. Favorable Probability = (4/6)*(1/3)

                                          =4/18

Total Favorable Probability = Probability of case 1+ Probability of Case 2

i.e. Required Probability P(W) = 4/18+ 4/18 = 4/9

(b) T=ball transferred is white

W=Selected ball from box b is white

P(T)=2/6

we have chosen white ball from box a and now we have two white balls and one red in box b.

The probability that a white ball is drawn from box b will be

P(W|T)=2/3.

So, P(T n W) = P(T)*P(W|T)

P(T)∗P(W|T)= 2/6∗2/3=2/9

We know, P(W)=4/9  (from a)

So, P(T|W)=P(T n W)/P(W)

            =(2/9)/4/9=1/2

sales tax: $112 * 1.09 = $122.08

If from a 130 m tall phone mast the angle of elevation are 73° and 41° then the distance between Carter and Naomi is nearly 189 meters.

What is angle of elevation?

The angle of elevation is an angle that is formed between the horizontal line and the line of sight. If the line of sight is upward from the horizontal line, then the angle formed is an angle of elevation.

According to the given question:

Let the distance of Carter and Naomi from from 130m tall phone mast be x and y respectively.

Angle of elevation from Carter to top is 73°

tan 73° = 130/x

Similarly angle of elevation from Naomi to top 41°

tan 41° = 130/y

Now, total distance between Carter and Naomi is x + y

∴ x + y = 130[ 1/tan 73° + 1/tan 41°]

       = 130[ 1/3.27 + 1/0.87]

       = 130 [ 4.14/2.8449]

       ≈ 189 meters

The grams of honey Mrs. Weasley will need to make the whole pan is 3/4 grams

From the question, we have the following parameters that can be used in our solution:

Grams of honey = 1/4 grams

Size of the pan = 1/3 of a pan

From the above parameter, we can calculate the grams of honey for a whole pan using:

Total grams of honey = Grams of honey/Size of the pan

Substitute the known values in the above equation

So, we have the following equation

Total grams of honey  = (1/4)/(1/3)

Evaluate the quotient

Total grams of honey  = 3/4

Hence, the amount is 3/4 grams

Answer:

The question is possibly mistyped.  The response below explains why, but also answers the questions based on a imagined relationship, instead of the one given.

Step-by-step explanation:

The equation 30 + 1.25x = 15 + 25X cannot be interpreted in the manner the questions are written.  It is really only an expression, since there is no y in the equation, only x.  We can, however, solve for x:

30+1.25x = 15 + 25x

30 - 15 = 25x - 1.25x

15 = 13.75x

x = (15/13.75)

x = 1.0909

There is no other information to discern what x represents.  It could be light years to a particular comet, grams of a reagent, hours until the meat is cooked, or anything the imagination allows.

If, however, the equation were something like:

  y = 1.25x + 15

we could answer the questions, as follows;

A pet sitter charges a flat fee of $15

sitter charges a flat fee of $15 plus $1.25/hr

Type I error would be that we conclude to reject the null hypothesis that the percentage of households with more than 1 pet is equal to 65 % when that percentage is actually equal to 65%.

Type II error would be that we fail to reject the null hypothesis that the percentage of households with more than 1 pet is equal to 65 % when that percentage is actually different from 65%.

We are given that the percentage of households with more than 1 pet is 65%.

Let p = population % of households with more than 1 pet

So, Null Hypothesis,  : p = 65%     {means that the percentage of households with more than 1 pet is equal to 65 %}

Alternate Hypothesis,  : p  65%      {means that the percentage of households with more than 1 pet is different from 65 %}

Type I error states that the null hypothesis is rejected given the fact that null hypothesis was true. Or in other words, it is the probability of rejecting a true hypothesis.

So, in our case, type I error would be that we conculde to reject the null hypothesis that the percentage of households with more than 1 pet is equal to 65 % when that percentage is actually equal to 65%.

Type II error states that the null hypothesis is accepted given the fact that null hypothesis was false. Or in other words, it is the probability of accepting a false hypothesis.

So, in our case, type II error would be that we fail to reject the null hypothesis that the percentage of households with more than 1 pet is equal to 65 % when that percentage is actually different from 65%.

The cost of 15 cans will be AED 48.

According to the question,

We have the following information:

Cost of 10 cans = AED 32

Now, in order to find the cost of 15 cans, first we will find the cost of 1 can by dividing the total cost of 10 cans by the number of cans.

So, we have the following expression:

Cost of 1 can = 32/10

Cost of 1 can = AED 3.2

Now, we will find the cost of 15 cans using multiplication:

Cost of 15 cans = 15*3.2

Cost of 15 cans = AED 48

Answer:

[tex]\textsf{C)} \quad f^{-1}(x)=\dfrac{1}{4}(x^2-5), \;\; x \geq 0[/tex]

Step-by-step explanation:

Given function:

[tex]f(x)=\sqrt{4x+5}[/tex]

The domain of the given function is restricted to x ≥ -⁵/₄.

Therefore, the range of the given function is restricted to f(x) ≥ 0.

The inverse of a function is its reflection in the line y = x.

To find the inverse of a function, swap x and y:

[tex]\implies x=\sqrt{4y+5}[/tex]

Rearrange the equation to make y the subject:

[tex]\implies x^2=4y+5[/tex]

[tex]\implies 4y=x^2-5[/tex]

[tex]\implies y=\dfrac{1}{4}(x^2-5)[/tex]

Replace y with f⁻¹(x):

[tex]\implies f^{-1}(x)=\dfrac{1}{4}(x^2-5)[/tex]

The domain of the inverse of a function is the range of the original function.  

Therefore, the domain of the inverse function is x ≥ 0.

Therefore, the inverse of the given function is:

[tex]f^{-1}(x)=\dfrac{1}{4}(x^2-5), \;\; x \geq 0[/tex]
