Answer:
Kindly check explanation
Step-by-step explanation:
Given the data below :
x : 89.3 68.6 32.7 37.3 39.7 46.7 66.1 79.4 66.4 52.1 47.3 64.4 53.7 63.4 46.2 63.0 92.1 57.6
Mean(m) = ΣX / n
ΣX = 1066 ; n = number of observations = 18
Mean(m) = 1066 / 18
Mean = 59.22
Standard deviation (σ) :
Using the online standard deviation calculator :
σ = √(Σ(x - m)²/n-1)
σ = √264.198395
σ = 16.72
The mean amount poured into a glass for the 18 samples is 59.22 while the variation in the data samples from the mean value is 16.72.
typical amount poured into a short, wide glass is 19.7 mL. A typical deviation from the mean amount poured is_____mL.
(59.22 - 19.7) mL = 39.52mL
Mean amount poured into a tall slender glass = 51.283
Mean (short wide glass) = 59.22mL
Mean (tall slender glass) = 51.283mL
Short wide glass > tall slender glass
How do you these two questions?
Answer:
dy/dx = e⁻²ᵗ (1 − t)
d²y/dx² = -e⁻³ᵗ (3 − 2t)
(1.5, ∞)
Step-by-step explanation:
x = eᵗ
y = te⁻ᵗ
dx/dt = eᵗ
dy/dt = -te⁻ᵗ + e⁻ᵗ
dy/dt = e⁻ᵗ (1 − t)
dy/dx = (dy/dt) / (dx/dt)
dy/dx = e⁻ᵗ (1 − t) / eᵗ
dy/dx = e⁻²ᵗ (1 − t)
d²y/dx² = d(dy/dx)/dt / (dx/dt)
d²y/dx² = (-e⁻²ᵗ − 2(1 − t) e⁻²ᵗ) / eᵗ
d²y/dx² = -e⁻²ᵗ (1 + 2(1 − t)) / eᵗ
d²y/dx² = -e⁻³ᵗ (3 − 2t)
The function is concave up when the second derivative is positive. -e⁻³ᵗ is always negative, so the second derivative is positive when 3 − 2t is negative.
3 − 2t < 0
3 < 2t
t > 3/2
Or, in interval notation, (1.5, ∞).

What were each tax totals. What is the gross pay. What is the net pay. Show your work
Answer:
$440$66, $35.20, $30.80$308Step-by-step explanation:
Gross pay means the amount of money you get without any tax reductions.
40 * 11 = $440
Find the value of all the taxes.
440 * 0.15 = $66
440 * 0.08 = $35.20
440 * 0.07 = $30.80
Net pay means the amount of money you get with tax reductions.
440 - 66 - 35.20 - 30.80 = $308
Best of Luck!

A cashier at the grocery store rung up 2 customers in 8 minutes. At this rate, how many customers can he ring up in 30 minutes?
Ok so here you go..
He takes 8 minutes to ring up 2 costumers
In 1 minute,he will ring 2/8 customers
In 30 minutes= 2/8 *30= 7.5
The answer doesn't make sense so maybe your data is incorrect
11 = -3k - 22 -8k what is the value of k?
Answer:
k = -3
Step-by-step explanation:
Step 1: Write equation
11 = -3k - 22 - 8k
Step 2: Solve for x
Combine like terms: 11 = -11k - 22Add 22 to both sides: 33 = -11kDivide both sides by -11: -3 = kRewrite: k = -3Step 3: Check
Plug in k to verify it's a solution.
11 = -3(-3) - 22 - 8(-3)
11 = 9 - 22 + 24
11 = -13 + 24
11 = 11

The owner of a restaurant serving Continental-style entrees was interested in studying ordering patterns of patrons for the Friday-to-Sunday weekend time period. Records were maintained that indicated the demand for dessert during the same time period. The owner decided to study two other variables, along with whether a dessert was ordered: the gender of the individual and whether a beef entrée was ordered. The results are as follows:
GENDER

Solve for x - PLEASE NEED HELP, this is my 3rd time posting it.
Answer:
[tex]x=58[/tex]
Step-by-step explanation:
First, remember that the maximum degree of an angle totals 360°.
Since we already have 294°, this means that what is left must total [tex]360\textdegree - 294\textdegree= 66\textdegree[/tex].
Therefore, this means that our two smaller angles must equal 66°. So:
[tex](36)+(x-28)=66[/tex]
Solve for x. Add on the left:
[tex]x+8=66[/tex]
Subtract 8 from both sides. Therefore, the value of x is:
[tex]x=58[/tex]

Fatima earned an 85 average in her science class. The average is based on 6 tests that she takes over the span of the marking period. On her first four tests she earned an 83, a 78, an 87, and an 80. On her sixth test she scored 8 points more than on her fifth test.
Let x be the score Fatima received on her fifth test. Set up an equation using x that models this scenario. Solve the equation and state what Fatima earned on her fifth and sixth tests.
Answer:
Fifth Score = 87
Sixth Score = 95
Step-by-step explanation:
Given
[tex]Average = 85[/tex]
[tex]Scores = 83, 78, 87, 80[/tex]
[tex]Fifth\ score = x[/tex]
[tex]Sixth\ Score = 8 + x[/tex]
Required
Set up an equation
Solve for the fifth and sixth score
Average is calculated as thus:
[tex]Average = \frac{\sum x}{n}[/tex]
[tex]Average = \frac{83 +78 + 87 + 80 + x + 8 + x}{6}[/tex]
Substitute 85 for Average
[tex]85 = \frac{83 +78 + 87 + 80 + x + 8 + x}{6}[/tex]
[tex]85 = \frac{83 +78 + 87 + 80 + 8+ x + x}{6}[/tex]
[tex]85 = \frac{336+ 2x}{6}[/tex]
Multiply both sides by 6
[tex]85 * 6 = 336 + 2x[/tex]
[tex]510= 336 + 2x[/tex]
Solve for 2x
[tex]2x = 510 - 336[/tex]
[tex]2x = 174[/tex]
Solve for x
[tex]x = 174/2[/tex]
[tex]x = 87[/tex]
Hence:
[tex]Fifth\ Score = 87[/tex]
[tex]Sixth\ Score = 87 + 8[/tex]
[tex]Sixth\ Score = 95[/tex]

Lisa was throwing a dart at a target. She threw 50 times with her left hand and 50 times with her right hand. The histograms show the distance Lisa missed the target by each time. Make an inference about which hand Lisa has better aim with based on the median of each data set. Justify your response.
Answer:
wow left handed i can't try that i'm very bad at throwing left handed plus he got closer more times then his right wait no she
Step-by-step explanation:
Answer:
The left hand is more accurate.
Step-by-step explanation:
If you look at the graph, it will look like the right hand is more accurate, due to the fact that it has a closer distance than the left. However, the right hand actually never have hit the target while the left did more than once.
What is 2/3 - 5/12 x 9/20 divided by3/4
Answer: 5/12
Step-by-step explanation:
Our common denominator is 60.
25 * 27 = 675
675 / 45 = 15
40 - 15 = 25
Since our denominator is 60, 25/60 is our answer.
25 / 60 simplified is 5 / 12.

Given problem:
Write 4.2678 x 10⁵ in decimal form;
Solution
To do this simply multiply by 100000 or move the decimal the right in five places.
4.2678 x 10⁵;
4.2678 x 100000 = 426780
The answer is 426780
If the exponent is a negative power, move the decimal to the left.

tonya bought a blanket for 33.35, a pillow for 11.25, and gloves for 16.75. She paid 60 and the rest she borrowed from her friend. If tonya got 8.65 change from the cashier, how much did she borrow from her friend to pay for all the items
Lets break this down.
So, if you add up all the money, that would be 61.35. That leaves you with 1.35.
Next, to find how much she payed, you have to think, theres a one dollar bill, 5 dollar bill, 10 dollar bill, and so on.
So if you think about the left over change, and add it to the extra 1.35 it would be 10!
Hence, your answer is 10 dollars.
The money Tonya borrowed from her friend to pay for all the items is $10.
Given that, tonya bought a blanket for 33.35, a pillow for 11.25, and gloves for 16.75. She paid 60 and the rest she borrowed from her friend and she got 8.65 change from the cashier.
We need to find the money she borrowed from her friend to pay for all the items.
What is an equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side). Equations can be solved to find the value of an unknown variable representing an unknown quantity.
Let the money paid to the cashier be x.
Now, the total cost of the items=33.35+11.25+16.75
=$61.35
So, x=61.35+8.65
=$70
The money she borrowed from friend=70-60=10
Therefore, the money Tonya borrowed from her friend to pay for all the items is $10.

at a local zoo, adult visitors pay $3 and children visitors pay $1. on one day, the zoo collected a total of $720. if the zoo had 420 visitors that day, how many adults and how many children visited?
Answer:
150 adults and 270 children
Step-by-step explanation:
Let there are x adults and y children.
ATQ,
x+y=420
or
y=420-x ....(1)
Adult visitors pay $3 and children visitors pay $1. on one day, the zoo collected a total of $720.
ATQ,
3x+y=720...(2)
Put equation (1) in equation (2).
3x+420-x=720
2x=720-420
2x=300
⇒x=150
Put the value of x in equation (1)
y=420-150
⇒y=270
So, there are 150 adults and 270 children visited.
