Your probability is zero for two reasons.
1) The experimental probability of landing on 8 is 100%
2) There is no 10.

Here are the shopping times (in minutes) of ten shoppers at a local grocery store.

d1i1m1o1n [39]

The frequency which is to filled in the table is 3,1,2,4.

Given shopping time of ten shopkeeper: 36,20,32,18,20,33,28,34,37,23.

We have to complete the frequency in the table. Frequency of something is the number of times that number is coming.

Shopping time is given as 36,20,32,18,20,33,28,34,37,23.

Intervals for which frequency is given is 18 to 22, 23 to 27, 28 to 32, 33 to 37.

Numbers in the range 18 to 22=18,20,23 therefore 3

Numbers in the range 23 to 27=23 therefore 1

Numbers in the range 28 to 32=32 , 28 therefore 2

Numbers in the range 33 to 37=36, 33, 37, 34 therefore 4.

Hence the frequency which is to filled are 3,1,2,4.

Simple interest I in dollars is calculated using the formula I=prt, where p represents the principal, or amount in dollars tha

and we do this one the same way as the other.

$\bf ~~~~~~ \textit{Simple Interest Earned} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\dotfill&\$540\\ P=\textit{original amount deposited}\dotfill & \$4800\\ r=rate\to 4.5\%\to \frac{4.5}{100}\dotfill &0.045\\ t=years \end{cases} \\\\\\ 540=(4800)(0.045)t\implies \cfrac{540}{(4800)(0.045)}=t\implies 2.5=t$

In the lab, Leila has two solutions that contain alcohol and is mixing them with each other. Solution A is alcohol and Solution

torisob [31]

Answer:

300ml

Step-by-step explanation:

As values are missing in your question, the complete question is:

In the lab, Leila has two solutions that contain alcohol and is mixing them with each other. Solution A is 6% alcohol and Solution B is 20% alcohol. She uses 400 milliliters of Solution A. How many milliliters of Solution B does she use, if the resulting mixture is a 12% alcohol solution?

Considering x=ml of 20% solution B

Therefore, 400+x=ml of resulting 12% solution

Solution A alcohol+ solution B alcohol= Alcohol solution

6% (400)+ 20%x = 12%(400+x) ->(converting percentage into decimal)

.06*400+.2x=.12(400+x)

24+.2x=48+.12x

.08x=24

x=24/.08=300 ml

she used 300 milliliters of 20%Solution B in resulting mixture.

The height of a triangle is 4 feet less than the length of its base, b. The area of the triangle is 30 square feet.

Papessa [141]

Answer:

base(b)=10 and height(h)=6

Step-by-step explanation:

From the question,

base(b)=x feet

height(h)=(x-4) feet

Area(A)=30 square feet

Now,

We know,

Area of triangle(A)=1/2*b*h

or, 30=1/2*x*(x - 4)

or, 30=1/2*x^2 -4x

or, 30*2=x^2 -4x

or, 60=x^2 -4x

or, 0 = x^2 -4x -60

or, 0 = x^2 +6x - 10x -60

or, 0 = x(x + 6) -10(x + 6)

or, 0 = (x+6) (x-10)

Either,

x+6=0. or, x-10=0

or,x= -6. or, x= 10

Since, the base of the triangle can not be negative number then, x≠ -6feet but x=10feet

Lastly,

Height(h)=X - 4

=10 - 4

=6 feet

The equation of the line graph is y=__x+__

BigorU [14]

Answer:

Step-by-step explanation:

Formula is y= mx+b

b= slope intercept which is 3

m is the slope and it is 3/2 = 1.5

so...

y= __x+__

y= 1.5x+ 3

Hope this helped!
