The answer would be -17

Step-by-step explanation:

On evaluation of  19 - 11 + (-17) + (-19) + 11 will result in -17

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

Using the concept that

+ - = -

On opening the brackets,

19 -11 + -17 + - 19 + 11=19-11-17-19+11

=19-19-17-11+11

Volume of a Rectangular Prism:

V = lwh

Length: 12 centimeters

Height: 9 centimeters

Width: 2 centimeters

V = 12(9)2

V = 108 x 2

V = 216

V = 216cm^2

The volume of the prism is 216 cm³ with a length of 12 cm, a height of 9 cm, and a width of 2 cm. This is obtained by using the formula for the volume of a prism.

The volume of a prism is

V=B × h cm³

Where B is the base area of the prism and h is the height of the prism.

For the given prism,

length l=12cm

width w=2cm and

height h=9cm

Calculating the base area:

Since the prism has length and width, it is a rectangular prism

Thus,

B = l × w sq.cm

Then, the volume of the prism becomes

V= l × w × h cm³

On substituting the values

V= 12 × 2 × 9

  = 216 cm³  

Therefore, the volume of the given prism is 216 cm³.

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.

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.

Answer:

16 cups

Step-by-step explanation:

If Joanna bought a gallon container of milk at the store then  volume of the container in cups is 16.

A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.

Given that Joanna bought a gallon container of milk at the store.

We need to find the  volume of the container in cups

1 cup= 8 ounces

1 gallon =128 ounces

So divide 128 by 8

128/8

8 is the common divisor  for 128 and 8

So divide both numerator and denominator by 8

We get 16 cups

Hence, the volume of the container in cups is 16.

Answer:

(a) (x + 3)(2x + 7) = 0

(b) These solutions mean that for these two x values, f(x) is equal to 0. It's also where the graph of f(x) crosses the x-axis.

Step-by-step explanation:

(a) We set 4x² -26x + 42 equal to 0:

4x² -26x + 42 = 0

Let's divide both sides by 2 to simplify this a bit:

2x² - 13x + 21 = 0

Now, we need factors a and b of 2 and c and d of 21 such that ac + bd = -13. The factors of 2 are: 1 and 2, so let's say a = 1 and b = 2. The factors of 21 are: (1, 21), (3, 7), (-1, -21), and (-3, -7). We see that if c = -7 and d = -3, this works:

ac + bd = 1 * (-7) + 2 * (-3) = -7 - 6 = -13

So, the factored form is:

(x - (-3))(2x - (-7)) = 0

(x + 3)(2x + 7) = 0

(b) So now we need to solve this. Set each of the two parenthetical expressions equal to 0:

x + 3 = 0

x = -3

AND

2x + 7 = 0

x = -7/2

These solutions mean that for these two x values, f(x) is equal to 0. It's also where the graph of f(x) crosses the x-axis.

Answer:

a) 2(x - 3)(2x - 7) = 0

b) function is 0 when x = 3 or 7/2

Step-by-step explanation:

4x² - 26x + 42 = 0

2(2x² - 13x + 21) = 0

2[2x² - 6x - 7x + 21] = 0

2[2x(x - 3) - 7(x - 3)] = 0

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.

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.
