Type the correct answer in each box. write each answer as a fraction, using / for the fraction bar. wesley draws a card at random from a well-shuffled deck of playing cards. the probability that wesley draws an ace or a jack is . the probability that wesley draws a number card or a black card is .
The probability that Wesley draws an ace or a jack is 0.154 and the probability that Wesley draws a number card or a black card is 0.846
The probability of Ace or jackIn a standard deck of cards, we have:
Total = 52
Ace = 4
Jack = 4
Ace and Jack = 0
The probability is then calculated as:
P = P(Ace) +P(Jack) - P(Ace and Jack)
This gives
P = 4/52 + 4/52 - 0/52
Evaluate
P = 0.154
Hence, the probability that Wesley draws an ace or a jack is 0.154
The probability of Number card or black cardIn a standard deck of cards, we have:
Total = 52
Number card = 36
Black = 26
Number card and Black = 18
The probability is then calculated as:
P = P(Number card) +P(Black card) - P(Both)
This gives
P = 36/52 + 26/52 - 18/52
Evaluate
P = 0.846
Hence, the probability that Wesley draws a number card or a black card is 0.846

Solve for h
h - 3h - 8 = 14
H=?
Answer:
-22
Step-by-step explanation:
h-3h-8=14
-2h=14+8
-2h=22
h=-11
The initial step that must be taken before solving almost any problem is to understand what the problem is asking for us to do and what is provided to us to complete that goal. Looking at the problem statement, we can see that we are being requested to solve for h and we are provided an expression to do so. Let's begin solving the expression by combining like terms.
Combine like terms
[tex]h - 3h - 8 = 14[/tex][tex](h - 3h) - 8 = 14[/tex][tex](- 2h) - 8 = 14[/tex]Just a quick explanation on what combine like terms means, it basically just means to combine the coefficients of the numbers associated with the same variables. Like in this example we can combine h and -3h because they have have the variable h associated with them.
Add 8 to both sides
[tex](- 2h) - 8 = 14[/tex][tex](- 2h) - 8+ 8 = 14 + 8[/tex][tex]- 2h= 22[/tex]Divide both sides by -2
[tex]- 2h= 22[/tex][tex]\frac{- 2h}{-2}= \frac{22}{-2}[/tex][tex]h= \frac{22}{-2}[/tex]Simplify the expression
[tex]h= - \frac{22/2}{2/2}[/tex][tex]h= - \frac{11}{1}[/tex][tex]h= - 11[/tex]Therefore, after completing the steps above we were able to determine that the value of h is equal to -11.
. The Flower Bouquet flower shop charges $1.50 for placing an order and $0.50 for each flower ordered. Which equation could be used to find n,the number of flowers purchased if the total bill was $9. (1 point)
A $9 = (0.50 + 1.50)n
B 0.50n + 1.50 = $9
C $9 = 50n + 1.50
D 0.50 n + 1.50n = $9
The equation that could be used to find the number of flowers purchased if the total bill was $9 is:0.50n + 1.50 = $9.
Since each flower costs $0.50, multiplying the cost per flower by the number of flowers (n) gives the total cost of the flowers then 0.50n represents the cost of the flowers.
and, 1.50 represents the fixed cost for placing the order.
and $9 represents the total bill, which includes the cost of the flowers and the fixed cost.
By adding the cost of the flowers (0.50n) to the fixed cost (1.50), the equation sets the total bill equal to $9 we get the Equation as
0.50n + 1.50 = $9

(x - 4)(x + 23) = (x + 14)(x - 1) ← expand factors on both sides using FOIL
x² + 19x - 92 = x² + 13x - 14 ( subtract x² from both sides )
19x - 92 = 13x - 14 ( subtract 13x from both sides )
6x - 92 = - 14 ( add 92 to both sides )
6x = 78 ( divide both sides by 6 )

A man stands on his balcony, 140 feet above the ground. He looks at the ground, with his sight line forming an angle of
75 with the building, and sees a bus stop. The function d=140 sec 0 models the distance from the man to any object given
his angle of sight 0. How far is the bus stop from the man? Round your answer to the nearest foot.
The bus at an angle of sight of 75 degrees from the man is at a distance of 541 feet
How to determine the distance?The distance function is given as:
d = 140 sec(x)
Where x represents the angle of sight.
In this case,
x = 75
So, we have:
d = 140 sec(75)
Evaluate the product
d = 541
Hence, the bus at an angle of sight of 75 degrees from the man is at a distance of 541 feet

Ms. Stewart teaches three science classes. Her students are freshmen and
sophomores. Her student data are shown in the relative frequency table.
Which statement is false?
The statement that is false is 15% of her students are in biology, the correct option is A.
How to form two-way table?Suppose two dimensions are there, viz X and Y. Some values of X are there as X_1, X_2, ... , X_n and some values of Y are there as Y_1, Y_2, ... , Y_n
List them in title of the rows and left to the columns. There will be n \times k table of values will be formed(excluding titles and totals), such that:
Value(ith row, jth column) = Frequency for intersection of X_i and Y_j (assuming X values are going in rows, and Y values are listed in columns).
Then totals for rows, columns, and whole table are written on bottom and right margin of the final table.
For n = 2, and k = 2, the table would look like:
[tex]\begin{array}{cccc}&Y_1&Y_2&\rm Total\\X_1&n(X_1 \cap Y_1)&n(X_1\cap Y_2)&n(X_1)\\X_2&n(X_2 \cap Y_1)&n(X_2 \cap Y_2)&n(X_2)\\\rm Total & n(Y_1) & n(Y_2) & S \end{array}[/tex]
where S denotes total of totals, also called total frequency.
n is showing the frequency of the bracketed quantity, and intersection sign in between is showing occurrence of both the categories together.
We are given that;
The relative frequency table
Now,
This is because the relative frequency table shows that 0.15 of her students are freshmen in biology and 0.2 of her students are sophomores in biology. Therefore, the total percentage of her students in biology is 0.15 + 0.2 = 0.35, which is 35%, not 15%.
The other statements are true based on the relative frequency table.
Therefore, by the two-way table the answer will be 15% of her students are in biology.

O h(x) = 3x(x - 2) - 4
Answer:
h(x) = 3x(x - 2) - 4
Step-by-step explanation:
A quadratic function is a polynomial having a degree of 2.
==============================================================
On expanding h(x) :
⇒ h(x) = 3x (x - 2) - 4
⇒ h(x) = 3x² - 6x - 4
=============================================================
Hence, h(x) is a quadratic function.
Answer:
h(x) = 3x(x - 2) - 4
Step by-step explanation
A quadratic function has a degree of 2.
Firstly, we expand h(x):
h(x) = 3x (x - 2) - 4
OR h(x) = 3x squared - 6x - 4
Therefore, it is h(x)

three consecutive integers such that the smallest and three times the largest is 330 . what is the smallest integer?
Which equation represents the line that is parallel to y = -3 and passes through (-1, 6)?
y = __
Answer:
Step-by-step explanation:
We'll look for an equation with the form y=mx+b, where m is the slope and b the y-intercept (the value of y when x=0).
A parallel line will have the same slope as the reference line, in this case it is 0, since y = -3 has no x term in it [y is independent of x]. The line we want will have the form y=b, since m is 0. Put the given point, (-1,6) into this equation to find b:
y=b
