3. Jada can bake 12 cookies in 20 minutes. How many cookies can she bake 1
in 6 hours? HINT: 20 minutes and 6 hours are not equal, the hours MUST be
turned to minutes.
Answer:
she can bake 216 cookies in 360 minutes
Step-by-step explanation:
Answer:
Jada can bake 216 cookies in 6 hours.
Step-by-step explanation:
We need to know how many she can cook in 6 hours.
She currently bakes 12 every 20 minutes
we know that 1 hour is 60 minutes.
So we multiply 12 by 3 to get 36 because we know 60 minutes divided by 20 minutes is 3 minutes.
Now we know that she bakes 36 cookies in 1 hour
But it asked for 6 hours so simple multiplication:
36 cookies per 1 hour X 6 hours
36X6= 216

A used automobile dealership recently reduced the price of a used compact car by 10%. If the price of the car before discount was $18,100, find the discount and the new price.
Answer:
The discounted price would be 16290 as 18100 times 10 over 100 is 1810 so subtract that from 18100 and you get 16290

A survey showed that 70% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight. If 7 adults are randomly selected, find the probability that exactly 2 of them need correction for their eyesight.
Answer:
0.0250047
Step-by-step explanation:
Given that :
Proportion who need correction glasses = 70%
Number of trials = 7
Probability that exactly 2 needs correction glasses :
Using a binomial probability formula :
P(success) = p = proportion who need glasses = 0.7
P(x =x) = nCr * p^x * (1 - p)^(n - x)
P(x = 2) = 7C2 * 0.7^2 * 0.3^(7 - 2)
P(x = 2) = 7C2 * 0.7^2 * 0.3^5
P(x = 2) = 21 * 0.49 * 0.00243
P(x = 2) = 0.0250047

Step-by-step explanation:
To find the slope of a line, you need to find the [tex]\frac{rise}{run}[/tex] between two points. I will be using the points (-3, 2) and (-1, -2).
[tex]\frac{rise}{run}[/tex] = [tex]\frac{-2-2}{-1-(-3)}[/tex]
= [tex]\frac{-2-2}{-1+3}[/tex]
= [tex]\frac{-4}{2}[/tex]

g If the p-value for your test statistic in a test of hypothesis (for example, a t-test, one-tail) is 0.07 and the significance level alpha is set at 0.05, you conclude that: Both hypotheses H0 and H1 can be accepted The null hypothesis H0 cannot be rejected The null hypothesis H0 can be rejected The research hypothesis H1 can be accepted
Complete Question
If the p-value for your test statistic in a test of hypothesis (for example, a t-test, one-tail) is 0.07 and the significance level alpha is set at 0.05, you conclude that:
A
Both hypotheses H0 and H1 can be accepted
B
The null hypothesis H0 cannot be rejected
C
The null hypothesis H0 can be rejected
D
The research hypothesis H1 can be accepted
Answer:
The correct option is B
Step-by-step explanation:
From the question we are told that
The p-value is [tex]p-value = 0.07[/tex]
The level of significance is [tex]\alpha = 0.05[/tex]
Generally given that it is a one tail test then the possible value of
The null hypothesis is [tex]H_o : \mu = x[/tex]
Here [tex]\mu[/tex] is the mean and x is the value
the possible values of the alternative hypothesis is [tex]\mu > x \ \ or \ \ \mu < x[/tex]
Now from the value given we see that the [tex]p-value > \alpha[/tex] hence
The decision rule is

find the value of x then classify the triangle by its angles
Answer:
Step-by-step explanation:
3x + x + 60 = 180.
first, we add the x's together.
4x + 60 = 180
then we see if they all have a common multiple. in this case, they do. they are all divisible by 4, so we can use that.
x + 15 = 45
then, just subtract 15 from both sides, that way we get the variable by itself.
x = 30
also, it is a right triangle. the top angle (3x) multiplied by 3 is 90. any triangle that has a 90 degree angle is automatically a right triangle.
Step-by-step explanation:
3x+X+60=180
4x=180-60
X=120/4
X=30

The sum of the numbers is 30. What are the
three numbers?
Answer: 6, 21, 3
Step-by-step explanation:
2:7:1
Also, 2x 7x and 1x or just x
2x+7x+x = 30
10x = 30
x=3

The book store earned x dollars in profit. Last week, the total profit
increased by 5%. Which expression represents the book store's total
increase in profit?
Answer:
x + 0.05x
Step-by-step explanation:
Given
Earnings earned by the bookstore = x
percentage increase = 5%
Increment = 5% of x
Increment = 0.05x
book store's total increase in profit = Original earning + increment
book store's total increase in profit x + 0.05x
Hence the expression that represents the book store's total increase in profit is x + 0.05x

as a trinomial in standard form.
Given:
[tex](x+9)^2[/tex]
To find:
The given expression as a trinomial in standard form.
Solution:
We have,
[tex](x+9)^2[/tex]
Using the formula, [tex](a+b)^2=a^2+2ab+b^2[/tex], we get
[tex](x+9)^2=x^2+2(x)(9)+(9)^2[/tex]
[tex](x+9)^2=x^2+18x+81[/tex]
Standard form a trinomial is [tex]ax^2+bx+c[/tex].
[tex]x^2+18x+81[/tex] is in the standard form.
Therefore, the required expression is [tex]x^2+18x+81[/tex].

What is the coefficient: 4 - 2y
The coefficient of the variable y for the given equation 4 - 2y is -2.
What is the coefficient?A coefficient is a number that is being multiplied by the variable, i.e. the numerical term with variable, that is a number that is placed before another variable. While the variable represents some quantity, it may also represent a number, a function, etc. The letters a, b, c, x, y, and z are common symbols used for variables.
We have,
An equation 4 - 2y,
So,
In the above-given expression,
We have only one variable and one Constant term,
i.e.
Constant term = 4
And,
Variable term = -2y
So,
In the variable term,
The coefficient of y = -2
