Step-by-step explanation:

cancel the 1 and add 18+4=22

Hello.

The greater the negative number, the smaller (in value) it is.

Answer:

The expected value of the proposition is -$0.76.

Step-by-step explanation:

It is provided that a basketball player has made 291 out of 389 free throws.

Then rate of him making a free throw is,

[tex]P(\text{free throw})=\frac{291}{389}=0.7481[/tex]

The probability that he makes the next 2 free throws is:

[tex]P(\text{Next 2 free throws})=(0.7481)^{2}=0.5596[/tex]

The payout rules are:

Compute the expected value of the proposition as follows:

Expected value = $38 × P (Makes both) + (-$50) × P (Misses both)

                          [tex]=($38\times 0.5596)+(-$50\times (1-0.5596))\\=21.2648-22.02\\=-0.7552\\\approx -$0.76[/tex]

Thus, the expected value of the proposition is -$0.76.

Answer:

An expression will be said to be a perfect square trinomial if it takes the form of ax² + bx + c and if it satisfies the condition b² = 4ac.

Step-by-step explanation:

An expression which is obtained from the square of a binomial equation is known as perfect square trinomial.

Now, the conditions for which an equation will be called a perfect square trinomial are;

i) It is of the form: ax² + bx + c

I) It satisfies the condition: b² = 4ac.

Thus, the perfect square formula could take the following forms:

(ax)² + 2abx + b² = (ax + b)²

Or

(ax)² − 2abx + b² = (ax − b)²

Answer:

x = -2/3

Step-by-step explanation:

24 - 3x = -6x + 22

solve using inverse operations

24 - 3x = -6x + 22

    + 6x     + 6x

24 + 3x = 22

-24         -24

3x = -2

/3    /3

x = -2/3

Answer:

The security cost is 575

Step-by-step explanation:

Given

[tex]y = 151x + 575[/tex]

x = days

y = cost

Required

Determine the security deposit

From the equation, we understand that

x represent days:

This implies that

151x represent the payment for x days.

So, the security cost is 575

Answer:

u<19

Step-by-step explanation:

70 > 3u+13

you subtract 13 to both sides

which will give you 57

then you divide 3 and 57

leaving you of with 19

so your answer will be u<19

Answer:

B

Step by step explanation:

Y3 becomes y×3=u3

25 becomes 2×5=10=

Y3-10 squared=

Y3-210

Answer:

These types of angles are supplementary.

b. x + 75 +x +125 = 180

=> 2x = 180–200

=> 2x = –20

=> x = –20/2

=> x = –10

Bonus question:-

angle 1 = 48°

angle 2 = 180° –78°

= 102°

value of f :-

f + 48 + 102 = 180

=> f + 150 = 180

=> f = 180–150

=> f = 30°

Answer:

x=7

Step-by-step explanation:

since the two angles are equal, set them equal to each other and solve for x

7x+35=84

subtract 35 from both sides

7x=49

divide both sides by 7 to isolate x

x=7

Answer:D

Step-by-step explanation:s aThe function is always increasing because wether the value of x increases or decreases, the value of f(x) is increasing as well

Answer:

12 students

Step-by-step explanation:

Given that:

Eighth grade student = 72

Sixth grade student = 84

To group the students into the largest possible equal group with no student left, obtain the greatest common factor of the number of sixth grade and eighth grade student

Factors of 72:

72 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36

84 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 81

The greatest factor common in both numbers is 12.

Answer:

the answer is -2

Step-by-step explanation:

LOGIC lol

i’ll try to break it down for u so u can understand a little better.

the horizontal line is X and the vertical line is Y.

if u start in the middle going horizontally to the right u can find X and X will = 2

to find Y u need to start in the middle and count upwards until you find where the lines meet to create a point. Y = 1

X/Y = 2/1 which can simplify to 2

But since the line is going from left to right and going downwards it is negative hope this helped :)

Answer:

f(-2) =2

Step-by-step explanation:

f(-2) means we want the y value when x = -2

When x = -2 the function has a y value of 2

f(-2) =2

Answer:   [tex]3 \le x \le 5[/tex]

x is any real number between 3 and 5, including both endpoints

================================================

Explanation:

If A < B, then 1/A > 1/B. Applying the reciprocal flips the inequality sign.

For example, if 2 < 3, then 1/2 > 1/3. It might help to look at the decimal representations

1/2 = 0.500

1/3 = 0.333

We see that 1/2 is larger.

The inequality [tex]x < y < z[/tex] is the same as [tex]x < y \ \text{ and } \ y < z[/tex].

We've broken the single inequality into two smaller parts.

The given inequality breaks down into [tex]\frac{1}{6} \le \frac{1}{x+1}[/tex] and [tex]\frac{1}{x+1} \le \frac{1}{4}[/tex]

------------

Let's solve the first inequality for x

[tex]\frac{1}{6} \le \frac{1}{x+1}\\\\6 \ge x+1\\\\6-1 \ge x\\\\5 \ge x\\\\x \le 5[/tex]

Repeat for the other inequality as well

[tex]\frac{1}{x+1} \le \frac{1}{4}\\\\x+1 \ge 4\\\\x \ge 4-1\\\\x \ge 3\\\\[/tex]

-------------------------

We found that [tex]x \ge 3 \ \text{ and } \ x \le 5[/tex]

This is the same as [tex]3 \le x \ \text{ and } \ x \le 5[/tex] which combines to [tex]3 \le x \le 5[/tex]
