Answer:
x>10
Step-by-step explanation:
Think of the < and > signs as arrow marks
Whichever direction the arrows pointing, that's where you should plot.
The line graph shown goes rightwards, so use the sign that looks like it's pointing right. (>)
Finally, don't use the greater than or equal to sign because the circle isn't colored in. This means that it doesn't include 10, only numbers higher than 10.

Hyla has blocks of clay that are each 4 centimeters by 4 centimeters by 2 centimeters. She needs to cover the bottom of a box with a 2-centimeter tall layer of clay. The bottom of the box is 24 centimeters long and 20 centimeters wide. How many blocks of clay does Hyla need?
The number of blocks of clay needed by Hyla is 30 blocks
What is area?Area is the region bounded by a plane shape.
To calculate the number of blocks of clay needed by Hyla, we find the area of the bottom of the box and divide it by the area of the block.
Formula:
n = LWH/lwh............... Equation 1Where:
n = Number of blocks of clay needed by HylaL = Length of the bottom of the boxW = Width of the bottom of the boxH = Height of the boxl = Length of the bottom of the blockw = Width of the blockh = Height of the block.From the question,
Given:
L = 24 cmW = 20 cmH = 2 cml = 4 cmw = 4 cmh = 2cmSubstitute these values into equation 1
n = (24×20×2)/(4×4×2)n = 30Hence, The number of blocks of clay needed by Hyla is 30 blocks

deviation = ((absolute value of the difference between expected heads and observed heads) + (absolute value of the difference between expected tails and observed tails)) divided by total number of tosses. This value should always be positive.
1. In tossing one coin 10 times, what are your chances for tossing a head? a tail?: When I tossed one coin 10 times, I got heads 4 times and I got tails 6 times.
2. In tossing one coin 100 times, what are your chances for tossing a head? a tail?: I got heads 55 times and tails 45 times when I tossed one coin 100 times.
3. In tossing one coin 200 times, what are your chances for tossing a head? a tail?: When I flipped one 200 times, I got heads 92 times, and tails 108 times.
4. What is the deviation for 10 tosses?: 0.1
5. What is the deviation for the 100 tosses?
6. What is the deviation for 200 tosses?
7. How does increasing the total number of coin tosses from 10 to 100 affect the deviation?
8. How does increasing the total number of tosses from 100 to 200 affect the deviation?
When a coin is tossed ten times, the probability of getting a head will be 1/2.
How to solve the probability?In probability, one can either get a head or a tail. Therefore, when a coin is tossed ten times the probability of tossing a head will be:
= 5/10 = 1/2
In tossing one coin 100 times, the chances for tossing a head will be:
= 1/2 × 100 = 50
In tossing one coin 200 times, the chances for tossing a head will be:
= 1/2 × 200
= 100

Determine the exact value for each of the 6 trig functions for the point (-2, 6).
Answer:
Sine: 0.94
Cosine: -0.31
Cotangent: -0.3(infinite)
Cosecant: 1.05
Tangent: -3
Secant: -3.16
Formula for finding the 6 trigonometry functions
To find the sine, you must divide the opposite side by the hypotenuse, because the sine is the ratio or fraction whose angle is opposite to the adjacent angle.To find a cosine, you must divide the adjacent angle by the hypotenuse.When finding a cotangent, you must divide the adjacent angle by the opposite, since the cotangent is also a ratio, but not like a sine.When you are finding a cosecant, you divide the hypotenuse by the opposite angle.You find the tangent by diving the opposite angle by the adjacent angle. It is like finding the cotangent but backwards.Last but not least, the secant. You find the secant by dividing the hypotenuse by the adjacent angle.Finding opposite and adjacent angles
To find the opposite angle, one simple way to determine that is to find the opposite side to that angle you are trying to find. For instance, when finding an angle, one side is 200, the adjacent side is 500. We must divide the opposite angle by the adjacent angle to find the missing angle. 200/500 = 0.4, so the missing angle is 0.4.To find the adjacent angle, that is always the side right next to a given angle.Hope this helps!
Step-by-step explanation:
The six trig functions are
[tex] \sin( \alpha ) = \frac{y}{r} [/tex]
[tex] \cos( \alpha ) = \frac{x}{r} [/tex]
[tex] \tan( \alpha ) = \frac{y}{x} [/tex]
[tex] \csc( \alpha ) = \frac{r}{y} [/tex]
[tex] \sec( \alpha ) = \frac{r}{x} [/tex]
[tex] \cot( \alpha ) = \frac{x}{y} [/tex]
Where
[tex]r = \sqrt{ {x}^{2} + {y}^{2} } [/tex]
[tex]r = \sqrt{ - 2 {}^{2} + {6}^{2} } [/tex]
[tex]r = \sqrt{40} [/tex]
[tex]r = 2 \sqrt{10} [/tex]
So we just plug in -2 for x, 6 for y, and our r value into these functions.
[tex] \sin( \alpha ) = \frac{6}{2 \sqrt{10} } = \frac{3}{ \sqrt{10} } = \frac{3 \sqrt{10} }{10} [/tex]
[tex] \cos( \alpha ) = \frac{ - 2}{2 \sqrt{10} } = \frac{ - 1}{ \sqrt{10} } = \frac{ - \sqrt{10} }{10} [/tex]
[tex] \tan( \alpha ) = \frac{6}{ - 2} = - 3[/tex]
Csc is the reciprocal of sine.
[tex] \csc( \alpha ) = \frac{ \sqrt{10} }{3} [/tex]
Sec is the reciprocal of cosine
[tex] \sec( \alpha ) = - \sqrt{10} [/tex]
Cot is the reciprocal of tan
[tex] \cot( \alpha ) = - \frac{1}{3} [/tex]

Answer:
x = 2, y = 13, z = 1
Step-by-step explanation:
2 * 2 * 13 * 13 * 17 is equal to 2x * 13y * 17z.
knowing that 2x = 2 * x
therefore
2 * 2 * 13 * 13 * 17 * 1

f a seed is planted, it has a 85% chance of growing into a healthy plant. If 9 seeds are planted, what is the probability that exactly 1 doesn't grow?
The probability that exactly 1 doesn't grow will be 0.07
What is Probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
We can use Bernoulli estimation to solve this. P(g) = 0.85, probability of not growing into healthy plant P(n) = 1-P(g) = 1 - 0.85 = 0.15
Using the Bernoulli approximation:
P(n=1)=⁹C₁xP(n)¹.⁵xP(g)⁸.⁵
P(n=1)=9x0.15¹.⁵x0.8⁸.⁵
P(n=1)=0.07
Hence the probability that exactly 1 doesn't grow will be 0.07

Using a system of equations, it is found that there are 10 baskets that hold 4 meals in the shop.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are given by:
Variable x: Number of baskets that hold 2 meals.Variable y: Number of baskets that hold 4 meals.There are 25 baskets in the shop, hence:
x + y = 25 -> x = 25 - y
They can hold a total of 70 meals, hence:
2x + 4y = 70
2(25 - y) + 4y = 70
2y = 20
y = 10

[tex]\displaystyle x = \{ 17, 21, 24, 34 \}[/tex]
Step 2: Find Profit
To find the profit the store makes each day, we input the number of customers that visited the store each day into our given function:
For the day that had 17 customers:
[tex]\displaystyle\begin{aligned}f(17) & = 3.55(17) - 4 \\& = 60.35 - 4 \\& = \boxed{56.35} \\\end{aligned}[/tex]
∴ the butcher store made $56.35 when 17 customers visited the store.
For the day that had 21 customers:
[tex]\displaystyle\begin{aligned}f(21) & = 3.55(21) - 4 \\& = 74.55 - 4 \\& = \boxed{70.55} \\\end{aligned}[/tex]
∴ the butcher store made $70.55 when 21 customers visited the store.
For the day that had 24 customers:
[tex]\displaystyle\begin{aligned}f(24) & = 3.55(24) - 4 \\& = 85.2 - 4 \\& = \boxed{81.2} \\\end{aligned}[/tex]
∴ the butcher store made $81.20 when 24 customers visited the store.
For the day that had 34 customers:
[tex]\displaystyle\begin{aligned}f(34) & = 3.55(34) - 4 \\& = 120.7 - 4 \\& = \boxed{116.7} \\\end{aligned}[/tex]
∴ the butcher store made $116.70 when 34 customers visited the store.
