At a basketball game, A team made 56 successful shots. They were a combination of 1-point and 2-point shots. The team scored 95 points in all. Right and solve a system of equations to find the number of each type of shot.
QUESTION:
There were____ 2-point shorts and____ 1-point shots.
Answer:
95/3 = 31
31 ratio for 2 and 1 then make up the difference
there were 25 point and 45 ...1 point shots
but 32 x 3 makes 96 you will see the top answer is correct 25 2 points and 45 one points as we can distribute 50 and 45 easily as a fair 6/10 and 4/10 balance of 95 just like we do to find 60% of 95 or 40% of 95.
Hi Samantha heres an example for both questions see if you can try add the items and find a multiple to 95 for this question then divide by 3 and distribute like this example below which answers your other question about popcorn.
Step-by-step explanation:
462 = revenue
282 = amount sold
$1 = small
$3 = large
1. we add the amounts together = $4
2. We divide 462/4 = 460/4 = 115 so we are 2 out
3. In our workings we show 4 less +2 less = 4 x 115 = 460 +2 =462-6
456
111 = small $1
456-111 = 345 + 6 = 351 ( large $3 as we were 4+2 less we add 6 = 351
351/3 = 119 large. (we divide by price $3)
111 = small.(we keep)
To find equations
we know know on our workings we have 111 +351 we can call these s and l
s111 + l351 = s111 + l119
462 = 230
462/230 = 2sl mean price.
=====
We plug in again to find 1
462/230 + 1 = 2sl(+l)+x
1s x 1^2 x 1l^2 x x = 1 we rearrange the 1
1s x 1^2 x 3l we replace ^2 with 1
1s x 1 x 3l = 1
1 x 3l = 1/1s
3l = 1s
====
Now we can match s and l
3 / 1 + 4 = 460l
3 / 1 = 460/4l
3 / 1 = 120l
1 x 120-3l
1 x 117l
117 ( 351/3) = L you cna try rewriting this ( ) plug in in a new equation just added to show you how it works.
l = 357 = L I wrote capitals as the l looked like a number.
When we subtract total 462- 351 = s then s = 111
When you understand minus 6 may have made things more tricky try another number where the total 462 is rounded up by 3 to 465 or 470 an work in 30's and 10's then divide by 10 may be of some help/reflection to designing equations it helps you remember alternatives to find out distribution.
Find exact length of the third side
Answer:
37
Step-by-step explanation:
This is a right triangle so we can find the lengths by using the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
12^2 + 35^2 = c^2
144 +1225 = c^2
1369 = c^2
Take the square root of each side
sqrt(1369) = sqrt(c^2)
37 =c

In a data set with a normal distribution, the mean is 59 and the standard deviation is 3.
Part A
About what percent of the data lie between 53 and 62?
A. 68%
B. 83.85%
C. 81.5%
D. 50%
Part B
Complete: About 95% of the data lie between
Answer:
a) [tex]P(53<X<62)=P(\frac{53-\mu}{\sigma}<\frac{X-\mu}{\sigma}<\frac{62-\mu}{\sigma})=P(\frac{53-59}{3}<Z<\frac{62-59}{3})=P(-2<z<2)[/tex]
[tex]P(-2<z<2)=P(z<2)-P(z<-2)[/tex]
[tex]P(-2<z<2)=P(z<2)-P(z<-2)=0.97725-0.02275=0.9545[/tex]
b) [tex]a=59 +1.96*3=64.88[/tex]
And for the other limit we have:
[tex]a=59 -1.96*3=53.12[/tex]
And we will have 95% of the values between (53.12, 64.88)
Step-by-step explanation:
Part a
Let X the random variable of interest of a population, and for this case we know the distribution for X is given by:
[tex]X \sim N(59,3)[/tex]
Where [tex]\mu=59[/tex] and [tex]\sigma=3[/tex]
We are interested on this probability :
[tex]P(53<X<62)[/tex]
And we can solve this using the z score:
[tex]z=\frac{x-\mu}{\sigma}[/tex]
Using the last formula we got:
[tex]P(53<X<62)=P(\frac{53-\mu}{\sigma}<\frac{X-\mu}{\sigma}<\frac{62-\mu}{\sigma})=P(\frac{53-59}{3}<Z<\frac{62-59}{3})=P(-2<z<2)[/tex]
And we can find this probability with this difference:
[tex]P(-2<z<2)=P(z<2)-P(z<-2)[/tex]
And uing the normal standard distribution or excel we got:
[tex]P(-2<z<2)=P(z<2)-P(z<-2)=0.97725-0.02275=0.9545[/tex]
Part b
For this part we want to find a value a, such that we satisfy this condition:
[tex]P(X>a)=0.025[/tex] (a)
[tex]P(X<a)=0.975[/tex] (b)
As we can see on the figure attached the z value that satisfy the condition with 0.95 of the area on the left and 0.05 of the area on the right it's z=1.96.
If we use condition (b) from previous we have this:
[tex]P(X<a)=P(\frac{X-\mu}{\sigma}<\frac{a-\mu}{\sigma})=0.975[/tex]
[tex]P(z<\frac{a-\mu}{\sigma})=0.975[/tex]
But we know which value of z satisfy the previous equation so then we can do this:
[tex]z=1.96<\frac{a-59}{3}[/tex]
And if we solve for a we got
[tex]a=59 +1.96*3=64.88[/tex]
And for the other limit we have:
[tex]a=59 -1.96*3=53.12[/tex]
And we will have 95% of the values between (53.12, 64.88)
In a normal distribution with mean 59 and standard deviation 3, approximately 81.85% of the data lie between 53 and 62. And about 95% of the data lie between 53 and 65, which is two standard deviations from the mean.
Explanation:In a normal distribution, about 68% of the data lie within one standard deviation of the mean, about 95% lie within two standard deviations, and about 99.7% within three standard deviations.
Part A:
The range from 53 to 62 in this case is from -2 standard deviations from the mean (56) to +1 standard deviation (62). Looking at the empirical rule, we find that about 34.13% of data fall between the mean and -1 standard deviation, and 13.59% fall between -1 and -2 standard deviations. Similarly, about 34.13% of the data fall between the mean and +1 standard deviation. Therefore, the total percentage of data lying between 53 and 62 would be
34.13% + 13.59% + 34.13% = 81.85%, so option B is the closest.
Part B:
About 95% of the data lie between two standard deviations from the mean. Therefore, you would add and subtract two times the standard deviation from the mean, which would yield 59 - 2(3) = 53 and 59 + 2(3) = 65. Thus, about 95% of the data lie between 53 and 65.

your welcome and hope this helps
Final answer:
The Quadratic formula will give us the coordinates of the points of intersection of a line and a quadratic only when the value of the discriminant is positive or zero.
Explanation:
The Quadratic formula will give us the coordinates of the points of intersection of a line and a quadratic only when the value of the discriminant is positive or zero.
The quadratic formula is:
x = (-b ± √(b² -4ac)) / 2a
Where a, b, and c are the coefficients of the quadratic equation ax² + bx + c = 0.
The quadratic formula will give us the coordinates of the points of intersection of a line and a quadratic only when the value of the discriminant is positive or zero. The quadratic formula is derived from the standard form of a quadratic equation, which is ax² + bx + c = 0. To find the points of intersection between a line and a quadratic, we would substitute the y-component (or x-component, depending on the variable used) of the line equation into the quadratic equation and solve for the remaining variable using the quadratic formula.

Ahmed is riding the elevator in a building. The building has floors above and below ground level. Ahmed uses the expression below to describe his movement.
6 + (negative 8)
Which statement could describe Ahmed’s movement?
Final answer:
Ahmed's movement described by the expression 6 + (negative 8) suggests he moves from the sixth floor above ground level down to the second floor below ground level.
Explanation:
The expression Ahmed uses to describe his movement in the elevator is 6 + (negative 8). To understand this expression in the context of elevator movement, 6 could represent Ahmed starting on the sixth floor above ground level. The addition of negative 8 would signify moving 8 floors downward. Thus, the expression indicates that Ahmed moves from the sixth floor down to the second floor below ground level (since 6 - 8 equals -2). The negative result corresponds to floors below ground level. Therefore, the statement that could describe Ahmed's movement is: Ahmed moves from the sixth floor above ground level down to the second floor below ground level.

Find the surface area of the pyramid shown below. The base is a rectangle and the opposite
triangular faces are the same size and shape.
Answer:
SA = 397
Step-by-step explanation:
The area of the rectangle is L x W = 18 x 7 = 126
The area of the triangle[tex]\frac{1}{3}[/tex] face is
A = [tex]\frac{1}{2}[/tex]bh
A = [tex]\frac{1}{2}[/tex] 18 x 10
A = [tex]\frac{1}{2}[/tex] 180
A = 90
Since there are two triangles the same size we times by 2
90 x 2 = 180
The triangles on the left and right sides are two other sizes compared to the other two triangles
A = [tex]\frac{1}{2}[/tex]bh
A = [tex]\frac{1}{2}[/tex] 7 x 13
A = [tex]\frac{1}{2}[/tex] 91
A = 45.5
Since there are two triangles the same size we times by 2 again so it will be 91
Than we add them up
91 + 126 + 180 = 397

a. Vertex: (-1,-6) b. Vertex: (-6,-1) C. Vertex: (2,1)
d. Vertex: (1,6)
e. Vertex: (1,-6)
Answer:
A is the answer, (-1,-6) is the vertex.
Step-by-step explanation:
With any quadratic, the formula for the x coordinate of the vertex is -b/2a.
In this case it is -(-4) / 2(-2) = 4 / -4 = -1.
To find the y, simply substitute the x.
f(-1) = -2(-1)² – 4(-1) – 8 = -2 + 4 – 8 = 2 – 8 = -6
