Answer:
correct answer is D) $1.94.
Step-by-step explanation:
To solve this problem, we first need to calculate the total cost of the candy bars and the sodas. The candy bars cost $0.84 each, so 3 candy bars cost 3*$0.84=$2.52. The sodas cost $1.80 each, so 2 sodas cost 2*$1.80=$3.60. The total cost of the candy bars and sodas is $2.52+$3.60=$6.12.
Since you are going to split the cost with your friend, you will pay for half, which is $6.12/2=$3.06. You pay for your half with a five dollar bill, so you will receive $5-$3.06=$1.94 in change.
I hope it helps, let me know if you have another questions.
Answer:
Step-by-step explanation:
First, we need to find the total cost of the candy bars by multiplying the number of candy bars by the price per candy bar: 3 candy bars * $0.84/candy bar = $3*0.84=2.52Next, we need to find the total cost of the sodas by multiplying the number of sodas by the price per soda: 2 sodas * $1.80/soda = $2*1.8=3.60Then, we need to add the cost of the candy bars and the sodas to find the total cost: $2.52 + $3.60 = $<<2.52+3.6=6.12>>6.12Since you are paying for half of the total cost, you need to pay half of $6.12, or $3.06.If you pay for your half with a five dollar bill, you will receive $5 - $3.06 = $5-3.06=1.94 in change. Answer: 1.94.
Donte simplified the expression below. 4 (1 3 i) minus (8 minus 5 i). 4 3 i minus 8 5 i. negative 4 8 i. what mistake did donte make?
Donte made the mistake of not applying the distributive property correctly for the expression 4(1 + 3i). So, correct option is A.
The distributive property states that when a number is multiplied by a sum of terms, it should be distributed to each term individually. In this case, the number 4 should be multiplied by both 1 and 3i.
However, Donte incorrectly multiplied only the real part, 4, with 1, resulting in 4, and did not multiply the imaginary part, 3i, by 4. This mistake led to an incorrect simplified expression.
The correct application of the distributive property would yield 4 multiplied by both 1 and 3i, resulting in 4 + 12i. Therefore, the correct simplified expression would be:
4(1 + 3i) - (8 - 5i) = 4 + 12i - 8 + 5i = -4 + 17i.
So, the mistake Donte made was not applying the distributive property correctly for 4(1 + 3i). So, correct option is A.

Solve the formula for b2.
Area of a trapezoid:
A =1/2h (b1 + b2)
Answer:
b2 = 2A/h - b1
Step-by-step explanation:
A = 1/2h(b1+b2)
Multiply both sides by 2
2A = h(b1+b2)
Multiply both sides by 1/h
2A/h = b1+b2
Add -b1 to both sides
2A/h + -b1 = b2
The expression of b2 in terms of A, h, and b1 is expressed as; b2 = 2A/h - b1
How to find the area of a trapezoid?The area of a trapezoid is the half of the product of sum of its parallel sides to the height of that trapezoid (the distance between those parallel sides).
Thus, if we have:
Length of its parallel sides = 'a' and 'b' units respectively
Perpendicular distance between its parallel sides = 'h' units,
Then, we get:
\(A = \dfrac{1}{2}\times(a+b) \times h \: \rm unit^2\)
Given the formula for calculating the area of a trapezoid expressed as;
A = 1/2h(b1 + b2)
Multiply both sides by 2
2A = h(b1 + b2)
Multiply both sides by 1/h;
2A/h = b1 + b2
Add -b1 to both sides;
2A/h + -b1 = b2
Hence the expression of b2 in terms of A, h, and b1 is expressed as 2A/h + -b1 = b2.

cos(B) = 0.9
tan(B) = 0.6
csc(B) = 2
sec(B) = 1.1
cot(B) = 1.7
To find the values of the six trigonometric functions of angle B, we need to use the coordinates of the point (13, 6).
Given that the terminal side of angle B passes through the point (13, 6), we can calculate the values of the trigonometric functions as follows:
sin(B) = y / r
= 6 / √(13^2 + 6^2)
= 0.5
cos(B) = x / r
= 13 / √(13^2 + 6^2)
= 0.9
tan(B) = y / x
= 6 / 13
= 0.6
csc(B) = 1 / sin(B)
= 1 / 0.5
= 2
sec(B) = 1 / cos(B)
= 1 / 0.9
= 1.1
cot(B) = 1 / tan(B)
= 1 / 0.6
= 1.7
Therefore, the values of the six trigonometric functions of angle B are:
sin(B) = 0.5
cos(B) = 0.9

-3.5 < 5
|-3.5| < |5|
============================================
Explanation:
Any negative number is always smaller than any positive number. So that's why -3.5 is smaller than 5 and where -3.5 < 5 comes from. It might help to set up a vertical number line. Stuff on top is larger than stuff down below.
---------
The vertical bars represent absolute value. The result of |-3.5| is 3.5 because this is the distance from -3.5 to 0 on the number line. Likewise, |5| = 5.
So that's how we get to |-3.5| < |5| which is effectively saying -3.5 is closer to zero than 5 is to zero.
in a group of 150 students 20 are freshmen 30 are sophomores 49 are juniors and 51 are senior if a student is randomly selected what is the probability that we select a sophomore before a freshmen
In a group of 150 students, 20 are freshmen 30 are sophomores 49 are juniors and 51 are seniors if a student is randomly selected the probability that we select a sophomore before freshmen is 2.69%.
So the given data we get from the question is as follows,
Total number of students, N = 150
A number of freshmen students, F = 20
The number of sophomore students, S = 30
Number of junior students, J = 49
Number of senior students, R = 51
We need to find the probability of selecting a sophomore student before a freshman student. The probability that a sophomore student is selected first,
P(S) = Number of sophomore students/Total number of students
= S/N
Probability that a freshman student is selected after a sophomore student,
P(F|S) = Number of freshman students left/Total number of students left
= F/N-1
Where N-1 is used because one student has already been selected.
The probability that a sophomore student is selected first and then a freshman student is selected,
P(S∩F) = P(S) × P(F|S)
= S/N × F/N-1
Therefore, the probability of selecting a sophomore student before a freshman student is:
P(S∩F) = S/N × F/N-1P(S∩F)
= 30/150 × 20/149P(S∩
= 0.0269 or 2.69%
Therefore, the probability of selecting a sophomore student before a freshman student is 0.0269 or 2.69%.

Answer:
x = 22
Step-by-step explanation:
Solving for x means having x alone on the left side as in
x = some number
Since 8 is being subtracted from x on the left side, you need to do the opposite operation of subtracting 8. The opposite operation of subtraction is addition. That means you need to add 8 to the left side to get rid of the subtraction of 8. The rule with equations is that you must do the same operation to both sides of the equation. Therefore, you need to add 8 to both sides of the equation.
x - 8 = 14
Add 8 to both sides.
x - 8 + 8 = 14 + 8
On the left side, -8 + 8 = 0, so you end up with just x.
On the right side, 14 + 8 = 22, so you end up with 22.

In this study, the researchers are interested in understanding how viewers perceive details of three-dimensional shapes on computer screens. They manipulate the stimuli by presenting fully rendered cubes, cubes with incomplete sides, and cubes with missing corner information. By varying these components, the researchers aim to identify which elements are necessary for viewers to accurately perceive the shape.
Four participants are recruited for an intense study, indicating a small sample size. While a larger sample size would generally be preferred for generalizability, intense studies often involve fewer participants due to the time and resource constraints associated with conducting a large number of trials. This approach allows for in-depth analysis of individual participant performance.
The participants are trained on how to detect subtle deformations in the shapes, which suggests that the study aims to assess their ability to perceive and discriminate fine details. After the training, the participants' accuracy rates are measured across the three different figure conditions, likely reported as a percentage of correctly identified shape details.
To minimize potential biases, the trials are presented in different orders for each participant, using a random-numbers table to determine unique sequences. This randomization helps control for order effects, where the order of presenting stimuli can influence participants' responses.
