Answer:
1/2
Step-by-step explanation:
there are 13 cards in each type so
heart or diamond would mean either one so 13 +13=26
26/52
1/2
TOTAL NUMBER OF HEART CARDS= 13
TOTAL NUMBER OF DIAMOND CARDS= 13
PROBABILITY OF AN EVENT
= NUMBER OF FAVOURABLE OUTCOMES
TOTAL NUMBER OF POSSIBLE OUTCOMES
Probability of getting a heart card♥=13/52 =1/4
Probability of getting a DIAMOND card♦= 13/52 =1/4
Probability of getting a heart and a diamond card =26/52 =1/2

The scatter plot shows the average heights of children up to age 5.
Part A
Drag numbers to complete an equation for the trend line. Numbers may be used once, more than once, or not at all.
(22, 2.5, 18, 32, 4.5)
y = ?x + ?
Part B
Using the linear equation, predict the average height for a two-year old.
A. 15 inches
B. 22 inches
C. 31 inches
D. 35 inches
Answer:
(a) [tex]y = 4.5x + 22[/tex] -- The equation
(b) 31 inches
Step-by-step explanation:
Given
See attachment
Solving (a): The equation of the trend line.
We start by calculating the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where
[tex](x_1,y_1) = (0,22)[/tex]
[tex](x_2,y_2) = (4,40)[/tex]
So, we have:
[tex]m = \frac{40 - 22}{4 - 0}[/tex]
[tex]m = \frac{18}{4}[/tex]
[tex]m = 4.5[/tex]
The equation is then calculated using:
[tex]y = m(x-x_1)+y_1[/tex]
Where:
[tex](x_1,y_1) = (0,22)[/tex]
[tex]m = 4.5[/tex]
[tex]y = 4.5(x - 0) + 22[/tex]
Open bracket
[tex]y = 4.5x - 0 + 22[/tex]
[tex]y = 4.5x + 22[/tex]
(b) The height of a 2 year old.
To do this, we substitute 2 for x in [tex]y = 4.5x + 22[/tex]
[tex]y = 4.5 * 2 + 22[/tex]
[tex]y = 9+ 22[/tex]
[tex]y = 31[/tex]
The prediction is 31 inches
Classify the polynomial according to its degree and number of terms.
9
constant monomial
sixth-degree monomial
linear binomial
sixth-degree binomial
Answer:
constant monomial
Step-by-step explanation:
The polynomial, 9, has 1 term and its degree is 0. Therefore, the polynomial is a constant monomial.
The given expression is a constant monomial. Therefore, option A is the correct answer.
What is the polynomial?A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer. A polynomial comprises constants and variables, but we cannot perform division operations by a variable in polynomials.
Here given expression is 9.
A constant monomial is a term with only a constant number. There is no variable in a constant monomial.
So, 9 is a constant monomial.
The given expression is a constant monomial. Therefore, option A is the correct answer.

27=15+n I can not get this one ether
Answer:
n= 12
Step-by-step explanation:
27=15+n
step 1. simplify
27=n+15
step 2. flip the equation n+15=27
step 3. subtract 15 from both sides
n+ 15 - 15 = 27 - 15 =
n=12
Answer:
12.
Step-by-step explanation:
We don't have the other number, so we must do the reverse operation, which is subtraction. So we have to subtract 27 from 15. 7-5 is 2, and 20-10 is 10. Add those together and you get 12.
A certain city has a population of about 100,000. There are 3,101 people with red hair in the city. Which of these is closest to the probability that a randomly selected person in the city has red hair?
Answer:
3%
hope this helps!
Step-by-step explanation:
The closest probability of a randomly selected person in the city having red hair is approximately 0.03 (or 3%).
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
A certain city has a population of around 100,000 people. In the city, there are 3,101 people with red hair.
The required probability can be calculated by dividing the number of people with red hair by the total population of the city:
= 3,101 / 100,000
= 0.03101,
It can be rounded to 0.03.
Thus, the required probability is 0.03.

3(s + 4) = 30 what the value of s
Answer:
s=6
Step-by-step explanation:
Hope this helps :)
The value of s for the given expression 3(s + 4 = 30 will be 6.
What is an expression?A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
A statement expressing the equality of two mathematical expressions is known as an equation.
As per the given expression,
3(s + 4) = 30
Divide both sides by 3
s + 4 = 10
Subtract both sides by 4
s + 4 - 4 = 10 - 4
s = 6

Rearrange t= 5s + 4 to make s the subject
Answer:
Subject 's' in terms of 't'
[tex]s = \frac{t-4}{5}[/tex]
Step-by-step explanation:
Explanation:-
Given that the subject 't in terms are 's'
Given that t = 5 s +4
subtracting '4' on both sides, we get
t - 4 = 5s +4-4
t - 4 = 5 s
Dividing '5' on both sides ,we get
[tex]\frac{t-4}{5} = \frac{5s}{5}[/tex]
[tex]\frac{5s}{5 } = \frac{t-4}{5}[/tex]
[tex]s = \frac{t-4}{5}[/tex]

Answer:
2) (see image below)
3) x = 8
side(s) = 74
4) x = 10
EF = DE = 67
base = 31
Step-by-step explanation:
For No. 2, if you draw out two triangles with the corresponding angles, you can make it a lot easier. See the image below:
For No. 3, it is given that it's an equilateral triangle, meaning all sides and angles are congruent. So:
12x – 22 = 10x – 6 = 7x + 18
Instead of using all three at once, you can use any two. I'll be using:
12x – 22 = 10x – 6
2x = 16
x = 8
Plugging x in, we can get all the sides, because this is an equilateral triangle:
12x – 22
12(8) – 22
96 – 22
74
For No. 4, it is given that the triangle is an isosceles triangle where DE ≅ EF, so:
8x – 13 = 5x + 17
3x = 30
x = 10
Plugging in x for one of the congruent sides and the base, you can get your needed side length values:
8x – 13
8(10) – 13
80 – 13
67
x + 21
10 + 21

to understand thisyou need to know about:trianglesequationPEMDAStips and formulas:a straight line contains 180°a triangle contains 180°let's solve:equation for x
according to the question
110°+x=180°
x=180°-110°
x=70°
equation for y
according to the question
[tex]11 {0}^{o} + {40}^{o} + y = 18 {0}^{o} [/tex]
[tex]15 {0}^{o} + y = 180^{o} [/tex]
[tex]y = 18 {0}^{o} - 15 {0}^{o} [/tex]
[tex]y = 3 {0}^{o} [/tex]
equation for z
according to the question
90°+x+z=180°
90°+70°+z=180° (since x=70°)
160°+z=180°
z=180°-160°
z=20°
Answer:
X= 70
Z= 20
y= 30°
Step-by-step explanation:
Finding X:
Sum of angle in a straight line is 180
Therefore X = 180-110
Finding z:
Sum of angle in triangle is 180, and it’s a right angled triangle (90°)
Z= 180-(x+90)
Z= 180-( 70+90)
Finding y, look at the big triangle ABC:
There’s a right angle and <C is 40°,
Therefore <B is 180-(40+90)= 50°
<B= y + z
50° = 20° + y
y= 30°

Step-by-step explanation:
The perimeter of a rectangular field that measures 2 feet by 18 inches is _________ ft.
Answer:
7 ft
Step-by-step explanation:
As we know that the formula to find the perimeter of a rectangle is
P = 2 (l) + 2(w). With that being said, we can look at the question.
The answer should be given in terms of feet, so we will have to convert 18 inches to ft. In order to convert from inches to ft, you will have to divide by 12.
18 / 12 = 1.5ft
18 inches = 1.5 foot
Now we take the given values and put them into the formula to find the perimeter of the rectangular field.
2 (l) + 2(w) = 2 (2 ) + 2 (1.5) = 7ft
The perimeter of the rectangular field is 7ft.

- El resultado de la conversión de 350 km/h a m/s es:
A. 1.26x10 m/s
B. 1260 m/s
C. 97.22 m/s
Answer:
350 kilómetros por hora son 97,2222 metros por segundo ;)
The result of converting 350 km/h to meter per second is 97.22 m/s.
To convert from kilometers per hour (km/h) to meters per second (m/s), you need to apply the conversion factor.
The conversion factor for this conversion is 1 km/h = 0.2778 m/s.
To convert 350 km/h to m/s, multiply 350 by the conversion factor:
350 km/h×0.2778 m/s
= 97.22 m/s
Therefore, the result of converting 350 km/h to m/s is approximately 97.22 m/s.
