Answer:

\(\mathbf{ \dfrac{1}{8} \ box}\)

Step-by-step explanation:

Given that:

Steve divided 5/8 of a box evenly among 5 bottles. To determine the amount of baking soda added;

Then, mathematically:

\(=\dfrac{5}{8} \ box \div 5\)

\(= \dfrac{5}{8} \ box \times \dfrac{1}{5}\)

\(\mathbf{= \dfrac{1}{8} \ box}\)

Answer:

\(\mathrm{True\:for\:all}\:x\)

Step-by-step explanation:

\(\left(2x+3y\right)^2-24xy=\left(2x-3y\right)^2\)

\(\left(2x+3y\right)^2-24xy\)

\(=4x^2+12xy+9y^2-24xy\)

\(=9y^2-12xy+4x^2\)

\(\left(2x-3y\right)^2\)

\(a=2x,\:\:b=3y\)

\(=\left(2x\right)^2-2\cdot \:2x\cdot \:3y+\left(3y\right)^2\)

\(=4x^2-12xy+9y^2\)

\(9y^2-12xy+4x^2=4x^2-12xy+9y^2\)

\(\mathrm{Subtract\:}9y^2\mathrm{\:from\:both\:sides}\)

\(9y^2-12xy+4x^2-9y^2=4x^2-12xy+9y^2-9y^2\)

\(\mathrm{Simplify}\)

\(-12xy+4x^2=4x^2-12xy\)

\(\mathrm{Subtract\:}4x^2-12xy\mathrm{\:from\:both\:sides}\)

\(-12xy+4x^2-\left(4x^2-12xy\right)=4x^2-12xy-\left(4x^2-12xy\right)\)

\(\mathrm{Simplify}\)

\(0=0\)

\(\mathrm{Both\:sides\:are\:equal}\)

\(\mathrm{True\:for\:all}\:x\)

They both are like terms, so you can add up the coefficients together.

It will take them 2 hours to crash into each other. The two boys are standing 30 miles apart and are both going to start cycling towards each other at the same time. They are traveling at a constant speed of 15 miles per hour.

Since they are traveling towards each other, the total distance they will cover is the sum of the distances they each travel.
To find the time it takes for them to crash into each other, we can use the formula:
Time = Distance / Speed
The total distance they need to cover is 30 miles, and their speed is 15 miles per hour.
Time = 30 miles / 15 miles per hour = 2 hours
Therefore, it will take them 2 hours to crash into each other.

The probability that at least 4 accounting majors are on the committee is P(at least 4 accounting majors) = 1 - P(less than 4 accounting majors)

We can use the complement rule to solve this problem. The complement rule states that the probability of an event happening plus the probability of the event not happening is equal to 1.

In this case, we can find the probability that less than 4 accounting majors are on the committee and then subtract that from 1 to find the probability that at least 4 accounting majors are on the committee.

There are 6 accounting majors and 9 finance majors, for a total of 15 students.

To find the probability that fewer than 4 accounting majors are on the committee, we can use the binomial probability formula:

P(k) = (combination(8,k)) \(\times (6/15)^k \times (9/15)^{(8-k)\)

where k is the number of accounting majors on the committee.

To find the probability that fewer than 4 accounting majors are on the committee, we need to sum the probabilities for k = 0, 1, 2, and 3.

P(less than 4 accounting majors) = P(0) + P(1) + P(2) + P(3)

Finally, we can use the complement rule to find the probability that at least 4 accounting majors are on the committee:

P(at least 4 accounting majors) = 1 - P(less than 4 accounting majors)

You can calculate the exact probability using the binomial coefficient and the binomial probability formula and then subtract that from 1 to get the final probability.

The confidence interval will range from 0.365 and 0.675.

To construct the confidence interval, we can use the following formula:

CI = p ± zα/2  √(p(1-p)/n)

where:

p = sample proportion = 0.52

zα/2 = critical value for the 99% confidence level = 2.576

n = sample size = 50

Plugging in the values, we get:

CI = 0.52 ± 2.576 x [√(0.52(1-0.52)/50)]

CI = 0.52 ± 0.155

CI = (0.365, 0.675)

Therefore, we can say with 99% confidence that the true proportion of U.S. workers who have negotiated a pay raise is between 0.365 and 0.675.

QR = 30

Step-by-step explanation:

GHI ~ PQR means that PQR is the same shape and length ratios as GHI but is a different size.

All of the leg lengths of GHI are multiplied by something to get the leg lengths of PQR.

You're given the leg lengths 12 and 20. So you need to find out what 12 is multiplied by to get to 20. 12 * 5/3 = 20.

So multiply 5/3 by the other leg length 18.

18 * 5/3 = 30

So QR = 30

In mathematics, a shearing transformation is a linear transformation that moves points in a plane or a two-dimensional space by a fixed distance in a specified direction.

The shearing transformation that shears units in the vertical direction can be determined as follows: A shearing transformation matrix takes the following form:|1 c||0 1|where c is the shear factor. To shear the units in the vertical direction, set c equal to the desired vertical shear factor. In this case, the vertical shear factor is 2.|1 2||0 1|is the shearing transformation matrix that shears units in the vertical direction.

Therefore, the shearing transformation matrix that shears units in the vertical direction is:

| 1 s |

| 0 1 |

where "s" represents the amount of shear.

To determine the shearing transformation matrix that shears units in the vertical direction, we can consider a 2D coordinate system. In a 2D coordinate system, a shearing transformation matrix can be represented as:

| 1 s |

| 0 1 |

where "s" represents the amount of shear in the vertical direction. If we apply this transformation matrix to a point (x, y), the transformed coordinates would be:

x' = x + s * y

y' = y
