14ºC-27ºC=-13ºCA greenhouse owner wants to test the effectiveness of a new fertilizer on African violets. She has 60 violet seedlings that were grown for 8 weeks. She wants to test the new fertilizer on 10 of the plants, and decides to use a random number table to select a simple random sample. Which of the following correctly labels the population of violets?
The required answer is she needs to number each plant from 1 to 60 and randomly peek at 10 of them. Option c is correct.
A greenhouse owner wants to test. She has 60 violet seedlings that were grown for 8 weeks. She wants to test the new fertilizer on 10 of the plants and decides to use a random number table to select a simple random sample. Which of the following correctly labels the population of violets Is to be determined.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
As she has 60 seeds, firstly she must number each plant in order or randomly see the height, After that he can peek at random 10 plants to test the fertilizer.
Thus, the required answer is she needs to number each plant from 1 to 60 and randomly peek at 10 of them. Option c is correct.

What is Point-Slope Form? What is Slope Intercept Form? What is the Slope Formula?
i included pictures please help it closes in 30 minutes pls give exact answers
Answer:
For the first part
1.) Negative
2.)zero
3.) undefined
4.) positive
The point slope formula is y-y1=m(x-x1). It is best to use if you already know the slope and one other point on the line. It is used to find another point on the line.
The slope-intercept form is used to show a line. To use this form, you need to know the slope and the y-intercept.
The slope formula is y=mx+b. M is the slope while b is the y-intercept.

Step-by-step explanation:
how do i solve this question 2x-14=4(p+5) ? all ik it that i have to distribute first.
Answer:
x=(4p+34)/2
p=(2x-34)/4
Step-by-step explanation:
2x-14=4(p+5)
2x-14=4p+20
2x=4p+34
If you are solving for x, it would be:
2x/2=4p+34/2
x=(4p+34)/2
If you are olving for p, it would be:
2x-34=4p
Divide 4 from both sides:
(2x-34)/4=p or p=(2x-34)/4

Lisa and Audrey were selling pizzas to raise money for new cheerleading uniforms. Lisa
sold 7 pizzas for every 2 pizzas Audrey sold. Together they sold 288 pizzas. How many
pizzas did Lisa sell and how many pizzas did Audrey sell?
Answer:
Call the number of pizzas x;They buy pizzas from the supplier at:4x+100They sell at:7xWhen these two expressions match they will start to make a profit; so:4x+100=7xRearranging:3x=100x=1003=33.3So after the 33rd pizza they will start to make a profit.For example at the 34th they have payed:34%C3%974+100=236$ to the supplier;Selling they will get: 7%C3%9734=238$. sorry if this is complex
Write the function rule for the function shown below reflected in the given axis.
f(x)x; -axis
Let g(x) be the reflection of f(x) in the -axis. What is the function rule for g(x)?
g(x)
nothing
Answer:
The answer is "[tex]\bold{g(x) = -\frac{1}{2x} \ and \ g(x)= -3x-12}[/tex]".
Step-by-step explanation:
Please find the complete question in the attached file.
[tex]\to f(x) = 4x[/tex]
Following the y-axis reflexion, f(x) is 4(-x) = -4x after a [tex]\frac{1}{8}[/tex] vertical compression factor, f(x) is [tex]\frac{1}{8} \times -4x = \frac{1}{-2x}[/tex]
So, the [tex]g(x) = - \frac{1}{2x}[/tex]
The y axis reflecting indicates that its entire function is multiplied by -1
so, [tex]f(x)=3x+12^{-1}[/tex]
[tex]\to g(x)=-3x-12[/tex]

Two less than three-fourths of a number is, at most, negative seventeen. what is the range of values for the number?
Answer:
[tex]x\leq -20[/tex]
values ranging from minus infinity to negative 20
Step-by-step explanation:
we write the inequality associated with the text in terms of the unknown number "x" as:
[tex]\frac{3}{4} x-2\leq -17[/tex]
then, we solve for "x" by adding 2 to both sides, and then isolating "x" on the left as shown below:
[tex]\frac{3}{4} x-2\leq -17\\\frac{3}{4} x\leq -17+2\\\frac{3}{4} x\leq -15\\3\,x\leq -60\\x\leq -\frac{60}{3} \\x\leq -20[/tex]
then, the range of x-values is from minus infinity to negative 20

Find the integers m and n such that (m+n√2)(1-√2)²=-2+2√2
Answer:
m = n = 2
Step-by-step explanation:
(m + n√2)(1 - √2)² = -2 + 2√2
(m + n√2)(1 - 2√2 + 2) = -2 + 2√2
(m + n√2)(3 - 2√2) = -2 + 2√2
3m - 2m√2 + 3n√2 - 4n = - 2 + 2√2
(3n - 2m)√2 + 3m - 4n = 2√2 - 2
3n - 2m = 2
4n - 3m = 2
3n - 2m = 4n - 3m
n = m
4n - 3n = 2
n = 2
m = 2

How do you do this question?
Answer:
-0.391 < x < 0.391
Step-by-step explanation:
The Maclaurin series for cosine is:
cos(x) = ∑ (-1)ⁿ x²ⁿ / (2n)!
So the next term would be -x⁶/6!. When the absolute value of this is less than the error:
│-x⁶/6!│< 0.000005
x⁶ / 720 < 0.000005
x⁶ < 0.0036

The original price of a jacket for sale at a department store is $80. The store is having a 20%-off sale, and you have
a coupon that gives you an additional discount of 10% off the lowest sale price. How would you calculate the final
selling price of the jacket?
O Multiply the $80 original price by 0.2 and subtract the result from $80. Then multiply the new price by 0.1 and
subtract the result from the discounted price.
O Multiply the $80 price by 0.3.
O Multiply the $80 price by 0.8, and then multiply the $80 price by 0.9.
O Divide the $80 price by 0.8, and then divide the $80 price by 0.9
i think it’s the first one
You're right; the answer is the first choice.
Answer:
first option , $57.6
Step-by-step explanation:
$80 x 0.20 = $16
$80 - $16 = $64
$64 x 0.10 = $6.4
$64 - $6.4 = $57.6
above solution is the exact steps on the first option.
therefore the final price of the jacket is $57.6

If 4j+3=-5. what is j +9?
Answer:
7
Step-by-step explanation:
First, we solve for j in the first equation:
4j+3=-5
4j=-8
j=-2
Now we plug j into j+9:
-2+9=7
So j+9 is 7
