Answer:
1 7/8 - 1 5/8 = 2/8.
Step-by-step explanation:
The amount of milk in cups that Samuel had after he made biscuits is 1/4 cups.
What is Subtraction?Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.
The process of subtraction can also be termed as finding difference.
Given that,
Amount of milk Samuel had = 1 7/8 cups
Amount of milk used to make biscuits = 1 5/8 cups
We have to find the amount of milk left after he made the biscuits.
This is found by subtracting the total amount of milk by the amount of milk used to make the biscuits.
Amount of milk left = 1 7/8 - 1 5/8
= 2/8
= 1/4 cups
Hence 1/4 cups of milk will be left.

Answer:
Exponential
Step-by-step explanation:
The function g(x) described by the given table of values is most likely an exponential function because x increases by a constant factor and the values of g(x) increase or decrease by a consistent factor. This behavior aligns with the characteristics of an exponential function, where the variable x appears in the exponent. I put polynomial as my answer on the test and got it incorrect and then realized the answer was exponential.
A camera has a listed price of 643.99 before tax. If the sales tax rate is 9.75%, find the total cost of the camera with sales tax included. Round your answer to the nearest cent, as necessary.
Answer: $1,271.88
Step-by-step explanation:
The total cost of the camera with sales tax included will be 100% plus our sales tax:
100% + 9.75% = 109.75%
Dividing a percent (%) by 100 gives us a decimal:
109.75% / 100 = 1.975
We can multiply this decimal by the listed price of the camera to find our answer
643.99 * 1.975 = $1,271.88
The camera will cost $1,271.88 with sales tax.
A coin is flipped 8 times. Find the probability of the event: exactly 5 heads a. 0.625 b. 0.03125 c. 0.219 d. 0.0039
The probability of the event of getting exactly 5 heads in 8 tosses of a coin(assuming unbiased coin) is given by: Option C: 0.219 (approximately).
How to find that a given condition can be modeled by binomial distribution?Binomial distributions consists of n independent Bernoulli trials.
Bernoulli trials are those trials which end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))
Suppose we have random variable X pertaining binomial distribution with parameters n and p, then it is written as
[tex]X \sim B(n,p)[/tex]
The probability that out of n trials, there'd be x successes is given by
[tex]P(X =x) = \: ^nC_xp^x(1-p)^{n-x}[/tex]
The expected value and variance of X are:
[tex]E(X) = np\\ Var(X) = np(1-p)[/tex]
For this case, we've got:
A coin is flipped 8 times.To find: P(getting exactly 5 heads)Each coin flip is a bernoulli distribution as it has two possible outcomes (assuming any other outcome like coin landing standing straight etc ignored). Take success = getting head in a flip, and failure = not getting success= not getting head = getting tail as the outcome of the flip.
Now, each of those 8 flips are independent in terms of result of each other (assuming coin stays unbiased).
If we take:
X = number of heads out of those 8 flips = number of successes in those 8 bernoulli trials, then:
[tex]X \sim B(n = 8, p)[/tex]
where p is the probability of success = P(Getting head in an unbiased coin with head or tail as only possible outcomes) = 1/2 = 0.5 (as head can come in 1 way, and total outcomes is 2, all equally likely).
Thus, we get:
[tex]X \sim B(n = 8, p=0.5)[/tex]
Now, P(Exactly 5 heads in those 8 flips) = P(X = 5)
Using the probability function of the binomial distribution, we get:
[tex]P(X = 5) = \: ^8C_5(0.5)^5(0.5)^{8-5} = \dfrac{8\times 7\times 6\times 5\times 4}{5 \times 4 \times 3\times 2 \times 1} \times (0.5)^8 \approx 0.219[/tex]
Thus, the probability of the event of getting exactly 5 heads in 8 tosses of a coin(assuming unbiased coin) is given by: Option C: 0.219 (approximately).

Answer:
1.
First, I would solve for ACB.
Calculations:
63° = y?
I would do that because I know that angle 'y' is vertical to 63°, which is given. (Also vertical angles are congruent, meaning that the measure the same degrees).
2.
Second, I would solve for BAC.
Calculations:
x + 63 + 85 = 180
x + 148 = 180
-148 -148
x = 32°
I would do that because I know that there are two given angles so I could easily solve for the leftover angle, 'z', using the a + b + c = 180° formula.
3.
Next, I would solve for CED.
Calculations:
x + 130 = 180
-130 -130
x = 50°
I would do that because I know finding this angle will help me find angle CDE.
4.
Finally, I would solve for CDE.
Calculations:
x + 63 + 50 = 180
x + 113 = 180
-113 -113
x = 67°
I would do that because I know there are now two given angles so I could easily solve for the leftover angle, x, using the a + b + c = 180° formula.

Answer:
31/40
Step-by-step explanation:
Given expression:
[tex]\dfrac{2}{5} + \dfrac{3}{8}[/tex]
Note: Both fractions must have same denominators if we want to perform addition, subtraction, multiplication, or division.
The only way to simplify this expression is to have a common denominator, which can be determined by the LCM of 5 and 8.
⇒ Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40, 45...⇒ Multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72...Multiply the denominators with such a number that is equivalent to 40.
Note: The number you are multiplying should also be multiplied to the numerator.
[tex]\rightarrow \dfrac{2 \times 8}{5 \times 8} + \dfrac{3 \times 5}{8 \times 5}[/tex]
[tex]\rightarrow \dfrac{16}{40} + \dfrac{15}{40}[/tex]
Finally, simplify the expression to determine the solution.
[tex]\rightarrow \dfrac{31}{40}[/tex]
Since 31 is a prime number, we can't simplify this fraction. Thus, the final answer is 31/40.
Ah yes, adding fractions! Adding fractions can be a bit of a pain.
So, we have [tex]\frac{2}{5} + \frac{3}{8}[/tex].
To add fractions, the bottoms, or denominators, must be the same number. So we must multiply the fractions by certain numbers to make the denominators the same number. So let's go easy and make the denominator 40, because 8 goes into 40 and so does 5. So, to make 8 become 40, we'll multiply the whole fraction by 5. For 5, we'll multiply by 8.
[tex]5 * \frac{3}{8} = \frac{15}{40}[/tex]
[tex]8 * \frac{2}{5} = \frac{16}{40}[/tex]
Now we'll add the two fractions. When we add fractions we only add the tops, the numerators.
[tex]\frac{15}{40}+\frac{16}{40} = \frac{31}{40}[/tex]
Then we must reduce (or try to reduce). This fraction cannot be reduced, so the answer is simply [tex]\frac{31}{40}[/tex].

The hopper bin in the picture below is modeled by the two-dimensional figure beside it. The hopper bin is
composed of a cylinder, and 2 EQUAL cones. Let d be the center of the base of the cone.
52° cylinder cones
The diameter of the hopper is 36 ft and the height of the cylindrical portion is 20 ft. The measure of the acute
angle formed by the slant height of the cone and its base is 52°, determine and state, to the nearest cubic foot,
the volume of the hopper bin.
The hopper bin was constructed to hold a maximum of 500,000 pounds of feed. If feed weighs 22 pounds per cubic foot, can the carnival tent be filled to 85% of its volume and not exceed the weight limit? Justify your
answer.
The volume of the hopper bin is the amount of feed in it
The volume of the hopper bin is 35974 cubic feetThe carnival tent can be filled to 85% of its volume and not exceed the weight limitThe volume of the hopper bin
The given parameters are:
Height of cylinder, H = 20 ftDiameter of cylinder, D = 36 feetAngle, θ = 52°Start by calculating the radius (r) of the cones.
r = D/2 -------- because the cones and the cylinder have equal diameters.
So, we have:
r = 36/2 = 18
The height (h) of the cones is:
tan(θ) = h/r
This gives
tan(52) = h/18
Make h the subject
h = 18 * tan(52)
Evaluate
h = 23.04
The volume is then calculated as:
Volume = Volume of cylinder + 2 * Volume of cone
This gives
Volume = πr^2H + 2 * 1/3πr^2h
Volume = πr^2H + 2/3πr^2h
Factor out πr^2
Volume = πr^2(H + 2/3h)
Substitute known values
Volume = 3.14 * 18^2 * (20 + 2/3 * 23.04)
Evaluate
Volume = 35973.85 cubic feet
Hence, the volume of the hopper bin is 35974 cubic feet
The weight limit of the hopper binThe given parameters are:
Maximum weight = 500000 poundsFeed weight = 22 pounds per cubic feetFor a feed that weighs 22 pounds per cubic feet, the weight of the hopper bin would be:
Weight = 22 * 35974 pounds
Weight = 791428 pounds
At 85% full, the weight wuld be:
Weight = 85% * 791428 pounds
Weight = 672713.8 pounds
672713.8 pounds is greater than the weight limit of 500000 pounds.
Hence, the carnival tent can be filled to 85% of its volume and not exceed the weight limit

Answer:
(-2, 0)
Step-by-step explanation:
Standard form of a parabola with a horizontal axis of symmetry:

Show that the set a = (1, 2, 1); b = (0, 1, 0); c = (-2, 0, 2) is linearly dependent.
By definition of linear independence, the vectors in the set {a, b, c} are independent if
[tex]k_1\vec a+k_2\vec b+k_3\vec c=\vec0[/tex]
can only be obtained with the choice of k₁ = k₂ = k₃ = 0.
This vector equation corresponds to the system of linear equations
[tex]\begin{cases}k_1 - 2k_3 = 0 \\ 2k_1 + k_2 = 0 \\ k_1 + 2k_3 = 0\end{cases}[/tex]
The first equation says k₁ = 2 k₃, while the third one says k₁ = -2 k₃. This can only be possible if k₁ = k₃ = 0, and from the second equation it follows that k₂ = 0. So the given set is linearly independent (and *not* dependent).
