Answer:
9+x*-7=-19
9-7x=-19
-7x=-19-9
-7x=-28
x=-28/-7
x=4
The number 4 is the required expression.
What is PEMDAS?The abbreviation PEMDAS is used to indicate the sequence of steps to be taken when resolving expressions with multiple operations. P is for "parentheses," E is for "exponents," M is for "multiplication," D is for division, A is for addition, and S is for subtraction.
Let x be the required number.
And the given expression is the sum of 9 and the product of a number and -7 is -19
That means ,
9 + x × -7 = -19
Using PEMDAS,
9 - 7x = -19
-7x = -19 -9
-7x = -28
x = 4
Therefore, the required number is 4.

The ratio of boys to girls in Ms. Reedus's classroom is 2 to 3. There are 18 girls in the classroom. What is the total number of students in Ms. Reedus's class?
Answer: The final answer is 30.
Step-by-step explanation: The question says the ratio is 2 boys : 3 girls. There are 18 girls. Well, how did you get from 3 to 18? You multiply by 6. But whatever you do to the denominator you have to do with the numerator. So, multiply 2 and 6. That gives you 12 boys and 18 girls. Adding 12 and 18 gives you 30. Therefore, there are 30 students in the whole class.

summerize this:
I didn’t know what I was doing or what I believed in, except the United States of America and the Cleveland Browns. Sometimes, to break my addiction to the tube[1], I spent the night in a derelict shed with mushrooms growing from the rafter boards. Back-yard rehab. I used to read in there, or, anyway, swing my eyes over the pages of library books: “Out of Africa” (the girl I was in love with loved the move); Donal Trump’s autobiography; Kierkegaard; “Leaves of Grass”; a book about how to make a robot from an eight-track player. As long as nobody had assigned the book, I could stick with it. I didn’t know what I was reading. I didn’t really know how to read. Reading messed with my brain in an unaccountable way. It made me happy; or something. I copied out the first paragraph of Annie Dillard’s “An American Childhood” on my bedroom’s dormer wall. The book was a present from an ace teacher, a literary evangelist in classy shoes, who also flunked me, of course, with good reason. Even to myself I was a lost cause.

FRQ 2
At a particular coffee shop, 92% of customers order a beverage, 3% of customers order food alone (order food and not a beverage), and 12% of customers order food and a beverage. Suppose we randomly select a customer. Let B = the customer orders a beverage and F = the customer orders food.
a) What is P(F)? Interpret this value in context.
b) What is the probability that the customer orders food given that they order a beverage? Write this event in symbolic form and find the probability.
c) If 180 customers are randomly selected, how many of them can we expect to order neither food nor a beverage? Justify your response.
Answer:
a) P(F) = 0.15
b) P(F/B) = 0.13
c) 5% customers order neither food not beverage.
Further explanation is in the explanation section
Step-by-step explanation:
Solution:
Data given:
B = The customer orders a beverage
F = The customer orders food.
F + B = The customers order food and a beverage.
Percentage share:
F = 3%
B = 92%
F + B = 12%
a)
So, the Probability of B, the customer orders a beverage will be:
P(B) = 92% = 0.92
Probability of (F+B), the customers orders food and beverage will be:
P(F ∩ B) = 12% = 0.12
And we know that, 3% customers order food alone so,
P(F) - P(F ∩ B) = 3% = 0.03
So,
P(F) = (P(F) - P(F ∩ B)) + P(F ∩ B)
P(F) = 0.03 + 0.12
P(F) = 0.15
It means that 15% customer order food only.
b) Probability that the customer orders food given that they order a beverage.
P(F/B) = (Probability that the customer orders food given that they order a beverage.)
P(F/B) = P(F∩B)/P(B)
P(F/B) = 0.12/0.92 = 0.13
P(F/B) = 0.13
Symbolic form of the required probability is = P(F/B)
c) If 180 customers are randomly selected, how many of them can we expect to order neither food nor a beverage?
Probability of ordering food and beverage will be:
P(F U B)
So,
Probability of ordering neither food nor beverage will be = 1 - P(F U B)
And,
P(F U B) = P(F) + P(B) - P(F ∩B)
P(FUB) = 0.15 + 0.92 - 0.12
P(FUB) = 0.95
Probability of ordering neither food nor beverage will be = 1 - P(F U B)
Probability of ordering neither food nor beverage will be = 1 - 0.95
Probability of ordering neither food nor beverage will be = 0.05
Hence, 5% customers order neither food not beverage.
So, we have selected 180 random people so, 5% of 180 =
number of people order neither food nor beverage = 5/100 x 180
number of people order neither food nor beverage = 9 people
It means we can expect out of 180 people, 9 people will not order food or beverage.

Choose the answer that shows 5–15 rewritten using a positive exponent.
Answer:
The required answer is [tex]\dfrac{1}{5^{15}}[/tex].
Step-by-step explanation:
Consider the provided exponent.
The given exponent is [tex]5^{-15}[/tex].
We need to write it using a positive exponent.
So, use the property: [tex]a^{-m}=\dfrac{1}{a^m}[/tex]
By using the above property we can rewrite the given exponent as:
[tex]5^{-15}=\dfrac{1}{5^{15}}[/tex]
Hence, the required answer is [tex]\dfrac{1}{5^{15}}[/tex].

HELP! I will mark BRAINLIEST please!
Answer: A
Step-by-step explanation:
In this equation, the largest exponent is odd, so the two ends are going in different directions. Since the leading coefficient is positive, the left side is going down, while the right side is going up.
As y approaches negative infinity (goes down), x approaches negative infinity (goes left).
Simplified: as the y value decreases, the x value decreases.
As y approaches infinity (goes up), x approaches infinity (goes right).
Simplified: as the y value increases, the x value increases.
"in the table below, Identify the figure,find it's perimeter, and find it's area.". <- that's the question
Answer:
✔️Quarter circle
✔️Area = 38.5 cm² (nearest tenth)
✔️Perimeter = 25.0 cm (nearest tenth)
Step-by-step explanation:
✔️The figure given is a ¼ circle
Radius is given as = 7 cm
✔️Area = ¼(πr²)
Plug in the value of r
Area = ¼(π*7²)
Area = ¼(π*49)
Area = 38.5 cm² (nearest tenth)
✔️Perimeter = ¼(2πr) + 2r
Plug in the value of r
Perimeter = ¼(2*π*7) + 2(7)
Perimeter = ¼(14π) + 14
Perimeter = 25.0 cm (nearest tenth)
