Answer:
Bag of tulips = $ 7
Step-by-step explanation:
Given :
12d + 6t = 198
6d + 7t = 127 <====== Multiply this equation by -2
-12d - 14t = -254 <==== now add this one to the top equation ( this will eliminate 'd' )

A. The normal distribution curve can go below the x-axis, but just barely.
B. The tails (ends) of the normal distribution curve are allowed to curve back up away from the
x-axis.
C. The normal distribution can have two modes as long as the graph is symmetric.
D. The mean, median, and mode are located at the center.
The correct statement regarding the normal distribution is given by:
D. The mean, median, and mode are located at the center.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.Most measures of the normal distribution are concentrated around the center, which represents all of the mean, median and mode, hence option D is correct.

A mix of peanuts and raisins contains five peanuts for every two raisins
So if the total number of peanuts and raisins in a mix is 84, calculate the number of peanuts of raisins in the mix.
Answer:
60 peanuts and 24 raisins.
Step-by-step explanation:
First work out the divisor which is 5 + 2 = 7.
84 / 7 = 12.
So there are 12 * 2= 24 raisins and 5 * 12 = 60 peanuts.

Alex is standing still and throws a football with a speed of 10 m/s to his friend, who is also standing still. the two friends are standing 5 meters apart. which describes how each person observes the speed of the football? alex observes it as 10 m/s, and his friend observes it as less than 10 m/s. alex observes it as less than 10 m/s, and his friend observes it as 10 m/s. both alex and his friend observe it as 10 m/s. both alex and his friend observe it as less than 10 m/s.
The statement that describes how each person observes the speed of the football is both Alex and his friend observe it as 10 m/s.
To answer the question, we need to know what speed is.
What is speed?Speed is the distance moved per unit time
Since Alex is standing still and throws a football with a speed of 10 m/s to his friend, who is also standing still. If there were relative motion between Alex and his friend, that is Alex or his friend were moving, each person would observe a different speed for the football.
Since there is no relative motion between Alex and his friend, they both observe the same speed for the football.
So, both Alex and his friend observe it as 10 m/s.
So, the statement that describes how each person observes the speed of the football is both Alex and his friend observe it as 10 m/s.

-9x+2x+32=-10 The solution for X
Answer: x = 6
Step-by-Step Explanation:
=> -9x + 2x + 32 = -10
= -7x + 32 = -10
= -7x = -10 - 32 = -42
=> x = -42/-7 = 42/7 = 6
Therefore, x = 6

-9x+2x+32=-10. what is x?
[tex]\dashrightarrow\large\blue\textsf{\textbf{\underline{Answer \& How to solve:-}}}[/tex]
When solving an equation, we need to make sure all variables are on the
left-hand side, and all numbers are on the right-hand side.
There are numbers on both sides, so we need to move all of them to the right.
[tex]\bold{-9x+2x=-10-32}[/tex]
[tex]\bigstar[/tex] On simplification,
[tex]\bold{-9x+2x=-42}[/tex] Next, combine like terms (-9x+2x).
[tex]\bigstar[/tex] On further simplification,
[tex]\bold{-7x=-42}[/tex] Next, divide by -7 on both sides.
[tex]\bigstar[/tex] Which results in
[tex]\bold{x=6}[/tex]
Note:-It's always a good idea to make sure the solution is correct.
We can check that by substituting the value of x (x=6) in lieu of x (into the original equation) and seeing whether or not we have a true statement:-
[tex]\bold{-9(6)+2(6)+32=-10}[/tex]
[tex]\dagger[/tex] On simplification,
[tex]\bold{-54+12+32=-10}[/tex]
[tex]\dagger[/tex] On further simplification,
[tex]\bold{-42+32=-10}[/tex]
[tex]\dagger[/tex] Which results in
[tex]\bold{-10=-10}[/tex]
LHS=RHS, so our solution is indeed correct.
So we conclude that [tex]\boxed{\bold{x=6}}[/tex].

Find the quotient of 2 3/5 ÷ 1 2/5 Give your answer as a mixed number in its simplest form.
The quotient of 2 3 / 5 ÷ 1 2 / 5 as a mixed fraction is 1 6 / 7
What is quotient?Quotient is the answer obtained when we divide one number by another. Therefore,
2 3 / 5 ÷ 1 2 / 5
let's convert the mixed fraction to improper fractions.
2 3 / 5 = 13 / 5
1 2 / 5 = 7 / 5
Therefore,
13 / 5 ÷ 7 / 5 = 13/ 5 × 5 / 7
13/ 5 × 5 / 7 = 13 / 7 = 1 6 / 7

Step-by-step explanation:
when picking (ahem, buying) a soccer ball, there are 75 total possibilities.
the chance to pick a bad one is then
4/75 = 0.053333333...
now we are buying 3 balls out of the 75.
how many possible options do we have ?
picks cannot be repeated, and the sequence does not matter, so we need combinations :
C(75,3) = 75! / (3! × (75-3)!) = 75×74×73/(3×2) = 25×37×73 =
= 67,525 possible groups of 3 balls.
from all these possibilities, how many have 2 good and 1 bad ball ?
as many as options we have to pick 2 balls out of 71 and 1 out of 4 :
C(71,2) × C(4,1) = 71! / (2 × (71-2)!) × 4! / (1 × (4-1)!) =
= 71×70/2 × 4 = 71×70×2 = 9,940 possibilities
so, the total probability to buy 2 good and 1 bad ball is

The equations a = n, b = 2n + 6 and c = n² - 1 are polynomials, and the expression for ab - c is n² + 6n + 1
How to determine the expression for ab - c?The polynomials are given as:
a = n
b = 2n + 6
c = n² - 1
The expression ab - c is calculated using:
ab - c = n * (2n + 6) - (n² - 1)
Expand
ab - c = 2n² + 6n - n² + 1
Collect like terms
ab - c = 2n² - n² + 6n + 1
Evaluate
ab - c = n² + 6n + 1
Hence, the expression for ab - c is n² + 6n + 1

Enter an equation to represent the cost (C) of shipping a package based on its mass in pounds (p).
Answer:
C = 4p
Step-by-step explanation:
Because it starts at 0 pounds costs 0 dollars, we know it starts at the origin and has no y-intercept. Because it rises up 20 dollars for every 5 pounds, we can use rise/run to do 20/5 to get an increase of 4 dollars per pound.

Answer:
38.5 litres soup the hospital has to prepare daily to serve 250 patients.Step-by-step explanation:
As we given that A patient in a hospital is given soup daily in a cylindrical bowl of diameter 7 cm. If the bowl is filled with soup to a height of 4 cm.
So,
Heigth of cylinder = 4 cmDiameter of cylinder = 7 cmRadius of cylinder = 7/2 = 3.5 cm[tex]\bigstar[/tex]To Find Volume of soaps required in the hospital to prepare daily to serve 250 patients. Firstly we need to find The volume of Soap in each bowl for 1 patient.
Using formula:
[tex] \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf \red{\underbrace{Volume_{(Cylinder)} = \pi r^2 h}} \\ \\ [/tex]
On substituting the required values, we get:
[tex] \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf Volume_{(Cylinder)} = \dfrac{22}{7} \times {(3.5)}^{2} \times 4 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf Volume_{(Cylinder)} = \frac{22}{7} \times 12.25 \times 4 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf Volume_{(Cylinder)} = \frac{22}{ \cancel{7} } \times{ \cancel{ 49}} \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf Volume_{(Cylinder)} = 22 \times 7 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf{ \red{ \underbrace{Volume_{(Cylinder)} = 154 \: {cm}^{3}}}} \\ \\ [/tex]
Hence, We have get the volume of soap for 1 patient is 154 cm³.
Now we need to find the volume of soap for 250 patients:
[tex] \\ \: \: \: \: \: \: \dashrightarrow \: \: \: \: \: \: \sf 154 \times 250 \\ \\ \: \: \: \: \: \dashrightarrow \: \: \: \: \: {\red{\underbrace {\sf {38500 \: cm^3}}}} \\ \\ [/tex]
