Answer:
Hmm, okay. 2 + 2 = 4
Step-by-step explanation:
If you think about it, 1 2 3 4. 3 and 4 is two numbers, so automatically you could think 1 and 2 is two numbers because it's the same amount. So, there ya go. If you can't count up to 4, then you might need more help with the question. Hope this was helpful! :D

Damian has a bag that contains strawberry chews, cherry chews, and peach chews. He performs an experiment. Damian randomly removes a chew from the bag, records the result, and returns the chew to the bag. Damian performs the experiment 48 times. The results are shown below: A strawberry chew was selected 16 times. A cherry chew was selected 10 times. A peach chew was selected 22 times. Based on these results, express the probability that the next chew Damian removes from the bag will be cherry or peach as a fraction in simplest form.
Answer: 2/3
Step-by-step explanation:
The probability that the next chew Damian removes from the bag will be cherry or peach as a fraction in simplest form is 55/576
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability for the strawberry chews:
P(strawberry chews) = 16/48
Probability for the cherry chews:
P(cherry chews) = 10/48
Probability for the peach chews:
P(peach chews) = 22/48
Now the probability of cherry or peach = P(cherry)×P(peach)
[tex]=\frac{10}{48} \times\frac{22}{48}[/tex]
= 220/2304
= 55/576
Thus, the probability that the next chew Damian removes from the bag will be cherry or peach as a fraction in simplest form is 55/576

Find the missing side x
Answer:
x = 21.52
Step-by-step explanation:
Given:
hypotenuse (That has to be found out)
Side adjacent to the given angle
and an angle,
Hence we can say that Cos ratio would be used;
Cos(28) = 19 / x
x = 19 / Cos(28)
x = 21.52

What is the shape of the cross-section formed when a cylinder intersects a
plane as shown in the drawing?
O A. circle
B. oval
C. rectangle
OD. square
Answer: circle
Step-by-step explanation:
The shape of the cross-section is formed when a cylinder intersects the plane is a circle option (A) is correct.
What is a cylinder?In geometry, it is defined as the three-dimensional shape having two circular shapes at a distance called the height of the cylinder.
We know the volume of the cylinder is given by:
[tex]\rm V = \pi r^2 h[/tex]
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
As we know, the circle is a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
As we can see in the picture the cylinder is cut by a plane that is parallel to the base of the cylinder.
The base of the cylinder is a circle.
the shape of the cross-section is formed when a cylinder intersects a
the plane is a circle.
Thus, the shape of the cross-section is formed when a cylinder intersects the plane is a circle option (A) is correct.

. if 3, 2, y, 10 are in proportion, find the value of y
Answer:
y = 15
Step-by-step explanation:
Given :
3, 2, y, 10
If the numbers are in proportion :
We can thus say :
3/2 = y/10
Cross multiply
3 * 10 = 2 * y
30 = 2y
Divide both sides by 2
30 / 2 = 2y / 2
15 = y
Multiply the expression
2/3 (6x + 15y)
and simplify completely.
Answer: 4x+10y
you can't simplify 4x+10y
Amy is going on a 4 1/4 mile hike She has already hiked 2 3/4 miles. How many more miles does she have left to hike?
Answer:
2 1/4 left to hike
Step-by-step explanation:
2+2=4 3+1=4
Amy have 1 1/2 miles left to hike.
What is a word problem?A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation
For the given situation,
Amy is going on a hike = 4 1/4 miles
She already hiked = 2 3/4 miles
Amy's distance left to hike,
⇒ [tex]4\frac{1}{4} -2\frac{3}{4}[/tex]
⇒ [tex]\frac{17}{4} -\frac{11}{4}[/tex]
⇒ [tex]\frac{6}{4}[/tex]
⇒ [tex]\frac{3}{2}=1\frac{1}{2}[/tex]
Hence we can conclude that Amy have 1 1/2 miles left to hike.

Express the series using sigma notation. 1 + 4 + 16 + ... + 256.
a.

Please select the best answer from the choices provided
A
B
C
D
Answer:
D
Step-by-step explanation:
By looking at the terms, we can notice that each term is 4 times the previous term. This means the series is geometric and we can rule out options A and B because of this. We can find the first terms of both options C and D to get:
first term c: 4
first term d: 1
The first term of our series is one, so that must mean D is the answer.

Ms. Clint is comparing the sales of sweaters and gloves at her store for the past ten winter weeks.
Answer:
B. A linear function with a positive slope.
Step-by-step explanation:
A correlation can be defined as a numerical measure of the relationship existing between two variables (x and y).
In Mathematics and Statistics, a group of data can either be negatively correlated, positively correlated or not correlated at all.
1. For a negative correlation: a set of values in a data increases, when the other set begins to decrease. Here, the correlation coefficient is less than zero (0).
2. For a positive correlation: a set of values in a data increases, when the other set also increases. Here, the correlation coefficient is greater than zero (0).
3. For no or zero correlation: a set of values in a data has no effect on the other set. Here, the correlation coefficient is equal to zero (0).
A linear function has a positive relationship and as such an increase in one variable (input variable) causes an increase in the other variable (output variable) i.e the variables are directly proportional. Thus, the graph of a linear function is a straight-line and it has a positive slope which is always constant.
From the graph, we can deduce that the scatter points lie close to a straight line with a slope that is positive.
Hence, the type of function which best models the relationship between the sales of sweaters and gloves is a linear function.
Mathematically, slope is given by the formula;
[tex] Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} [/tex]
[tex] Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

Answer:
45.5 u²
Step-by-step explanation:
first we need to find the base of the triangle so we subtract 8-5=3, now since its 2 triangles we divide by 2 and we get 1.5 for each base of the triangles
area for a triangle: A=bh/2
A=(1.5)(7)/2
since its 2 triangles then multiply by 2
A= 10.5 u²
area for a rectangle: A=bh
A=(7)(5)
A= 35 u²
35+10.5 = 45.5 u²

write √−20 in simplest radical form
Answer:
2i√5
Step-by-step explanation:
Since √-20 is negative and therefore is not a real number, first change it to i√20, to resolve this. Next, find the two closest factors of 20:
1, 20
2, 10
4, 5
Then factor them once again:
2, 2, 5
After this, you get that √20= √2*√2*√5. With this, combine the two √2 to get 2 *√5. Lastly bring back the imaginary letter i, to get 2i√5.
Hope that helps.

Answer:
x=28
y=28
Step-by-step explanation:
Equation 1:
Dived both sides by 0.75 to remove 3/4 from x.
(x-12)=16
Now, add 12 to both sides.
x=28
Equation 2:
Same here, divide both sides by 0.75.
y-12=16
Add 12 to both sides.
y=28
6. Lines p and q are parallel, and line w is a transversal.
Answer:
B
Step-by-step explanation:
<2 and <7 are same side exterior angles, so you can say they add up to 180°.
We can write an equation to model the situation:
m<2 + m<7 = 180°
We can substitute the value of m<2,
132° + m<7 = 180°
m<7 = 48°
This is option B.
