A cooking school is teaching students how to make pasta noodles. The line plot displays how much flour each student used. How many total cups of flour did the students use to make the pasta?
Answer:
[tex]Total = 11\frac{1}{8}\ cups[/tex]
Step-by-step explanation:
Given
See attachment for plot
Required
Total number of cups used
The number of dot on each dataset represent the number of student
So, to get the total number of cups, we simply add the product of the number of cups and the number of student for each data item
So, we have:
[tex]Total = \frac{1}{8} * 6 + \frac{1}{4} * 5 + \frac{3}{8} * 2 + \frac{1}{2}*0 + \frac{5}{8} * 4 + \frac{3}{4} * 2 + \frac{7}{8} * 5[/tex]
[tex]Total = \frac{6}{8} + \frac{5}{4} + \frac{6}{8} + 0+ \frac{20}{8} + \frac{6}{4} + \frac{35}{8}[/tex]
Solve
[tex]Total = \frac{6+10+6+0+20+12+35}{8}[/tex]
[tex]Total = \frac{89}{8}[/tex]
[tex]Total = 11\frac{1}{8}\ cups[/tex]

The circumference of a circle is 87.92 inches. What is the circle's diameter? Use 3.14 for n.
Answer:
28
Step-by-step explanation:
circumference=diameter × π
diameter=87.92÷3.14=28
The diameter of circle will be 28 inches.
What is Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Given that;
The circumference of a circle is 87.92 inches.
Now,
We know that;
The circumference of circle = 2πr
Since, The value of π = 3.14
Substitute all the values, we get;
⇒ 87.92 = 2 × 3.14 × r
⇒ 87.92 = 6.28 r
⇒ r = 14
Thus, The diameter of circle = 2 × 14
= 28 inches

Robert plays cricket. He hit the ball in such a way that it goes up 180 feet
in 45 seconds. What is the speed of ball in feet per second?
Answer:
4 feet per second
Step-by-step explanation:
Hi there!
[tex]v=D/t[/tex] where v is velocity (speed), D is distance and t is time
Plug in the known values (D=180 feet, t=45 seconds)
[tex]v=180/45\\v=4[/tex]
Therefore, the speed of the ball is 4 feet per second.

Use the Quadratic Formula
Use the Quadratic Formula to find the zeros of the given
expression. Be sure to show your steps!
2x2-7x+3
Plz help no links
Answer:
1/2 and 3
Step-by-step explanation:
The quadratic formula is as given:
( -b±√(b^2-4ac) )/2a
To use it, plug in the a,b and c values.
ax^2+bx+c
In this case a is equal to 2, b is equal to -7, and c is equal to 3
plugging it into our formula gives us:
(-(-7)±√(-7^2-4*2*3) )/2*2
Which is equal to:
7±√(49-24) / 4
= 7±√25 / 4
=7±5 / 4
=2/4, 12/4= 1/2, 3

Jill sold one third of her dolls and bought 15 more she now has 25 dolls with how many did she start?
Answer:
15
Step-by-step explanation:
sold 1/3 so 2/3 remain
(2/3)x + 15 = 25
Subtract 15 from both sides
(2/3)x = 10
Multiply both sides by 3/2
x = 15
Find the geometric mean between 6 and 48 given the sequence (3,6,12,24,48,96)
Answer:
16.97
Step-by-step explanation:
the geometric mean value of a set of n numbers is the nth root of the product of all n numbers.
so, here this means
[tex]gm = \sqrt[6]{3 \times 6 \times 12 \times 24 \times 48 \times 96} [/tex]
this would be 16.97
but careful, the problem only asks for the gm between 6 and 48 of the sequence.
so, we actually only consider the subset 6, 12, 24, 48.
therefore
[tex]gm = \sqrt[4]{6 \times 12 \times 24 \times 48} [/tex]
this is also
[tex]gm = \sqrt[4]{3 \times 2 \times 3 \times 2 \times 2 \times 3 \times 2 \times 2 \times 2 \times 3 \times 2 \times 2 \times 2 \times 2} [/tex]
[tex] = \sqrt[4]{ {3}^{4} \times {2}^{10} } [/tex]
[tex] = \sqrt[4]{ {3}^{4} \times {2}^{4} \times {2}^{4} \times {2}^{2} } [/tex]
[tex] = 3 \times 2 \times 2 \times \sqrt[4]{ {2}^{2} } [/tex]
[tex] = 12 \times \sqrt{2} [/tex]
so, we could specify the result as that simple expression
or calculate it
gm = 16.97
hey, the result is the same as for the complete sequence.
coincidence ? no, it is not. but that is a subject for a different question.
3) Mary deposits £10000 in an account which pays 5.6% compound
interest per year.
How much will Mary have in her account after 5 years?
Answer:
FV= £13,131.66
Step-by-step explanation:
Giving the following information:
Initial Investment (PV)= £10,000
Interest rate (i)= 5.6%
Number of periods (n)= 5 years
To calculate the future value (FV), we need to use the following formula:
FV= PV*(1 + i)^n
FV= 10,000*(1.056^5)
FV= £13,131.66

[tex]\sqrt{5}[/tex] goes under the 'Between 2and 3' box.
([tex]\sqrt{3.5}[/tex])^2 is the exact same as 3.5, as the square root and square cancel each other out, so it goes in the 'Between 3 and 4' box.
