The area of a triangle is 60 cm2. Its base measures 5 cm. What is the triangle's
height on this base?


possible answers:
7.75 cm approximately
12 cm
24 cm
150 cm

Answers

Answer:

24

Step-by-step explanation:

Answer:

h = 24 cm

Step-by-step explanation:

Area = 1/2 b * h

b = 5 cm

Area = 60 cm^2

60 = 1/2 * 5 * h                   Multiply both sides by 2

60*2 = 2*1/2 *  5 * h            

120 = 5 h                           Divide by 5

24 = h

Đơn giản các biểu thức logic:
a- p ∧ (p ∨¬q) ∧ (¬p ∨ ¬q)

Answers

I can't conveniently copy the logical symbols you use, so I write

AND = ∧ (conjunction)

OR = ∨ (disjunction)

NOT = ¬

Tautologically,

p = (p AND q) OR (p AND NOT q)

and we can distribute the OR to get the equivalent statement

(p OR (p AND NOT q)) AND (q OR (p AND NOT q))

and again to get

((p OR p) AND (p OR NOT q)) AND ((p OR q) AND (q OR NOT q))

Now, q OR NOT q is always true, and p OR p is simply p, so we have

p = p AND (p OR q) AND (p OR NOT q)

This shows that p OR NOT q is already included in p, so our initial statement is simply

p AND (NOT p OR NOT q)

Distributing the conjunction, we get

(p AND NOT p) OR (p AND NOT q)

p AND NOT p is tautologically false, but we're considering a disjunction, so the truth value of p AND NOT q is the only value that's relevant. So, the initial statement collapses to

p AND NOT q

C. Two events are mutually exclusive if the intersection between the sample spaces of the two
events is not empty.
D. Two events are mutually exclusive if the union of the sample spaces of the two events is not
empty.

Answers

c is the correct answer

The statements which best defines the mutually exclusive events is two events are mutually exclusive if it is impossible for the two events to occur simultaneously (A).

When two events are said to be mutually exclusive?

The two events area said to be mutually exclusive when the cannot be take place simultaneously. For the two events, A and B, to be mutually exclusive,

[tex]P(A\cap B)=0[/tex]

Properties of mutually exclusive event:

Mutually exclusive event can not occur simultaneously.Probability of occurring the Mutually exclusive event for the same time is 0.They are disjoint.

Answers

Answer:

14

Step-by-step explanation:

This can be seen as a arithmetic series. It is the number of girls, let’s say g, plus the number of girls plus five boys. Deena, can be viewed as 1, plus 5 equals 6. Then Chloe, 2, plus 5 equals 7. And so on and on.

We can create an equation for this:

g+(g+5)=s

(s is the number of students.)

‘If the total number of students is 23;

g+(g+5)=23

We can solve this for:

2g = 23-5 ⇒

g=9

So the number of girls is 9, th number of boys is simply:

23-9=14

Determine the following probabilities. Enter your final answers as reduced fractions. Two coins are flipped. Find the probability that the first coin land on heads and the second coin lands on heads. Two cards are drawn from a deck of 52 cards. The first card is replaced before drawing the second card. Find the probability that the first card is hearts and the second card is a Jack. A single digit between 0 and 9 is randomly chosen, and a single letter from A to Z is randomly chosen. Find the probability that the number is 3 and the letter is a consonant. Two dice are rolled. Find the probability that first die lands on an even number and the second die is less than 3 .

Answers

Probabilities are used to determine the chances of events

(a) Coins

In a coin, the probability of the likely outcomes in each flip are:

Head = 1/2

Tail = 1/2

So, the probability that the first lands on head, while the second lands on tail is:

[tex]\mathbf{Pr = \frac 12 \times \frac 12}[/tex]

[tex]\mathbf{Pr = \frac 14}[/tex]

The probability that the first lands on head, while the second lands on tail is 1/4

(b) Deck of cards

There are 52 cards in a deck, 13 of which are hearts while 4 are jack.

The probability that the first card is heart is 13/52

The probability that the second card is jack is 4/51

So, the probability that the first selected card is heart, while the second is jack is:

[tex]\mathbf{Pr = \frac{13}{52} \times \frac{4}{51}}[/tex]

[tex]\mathbf{Pr = \frac{1}{51}}[/tex]

The probability that the first selected card is heart, while the second is jack is 1/51

(c) Digits and Letters

There are 10 digits between 0 and 9, so the probability of selecting 3 is 1/10.

There are 21 consonants, so the probability of selecting a consonant is 21/26

So, the probability of selecting 3 and a consonant is:

[tex]\mathbf{Pr = \frac{1}{10} \times \frac{21}{26}}[/tex]

[tex]\mathbf{Pr = \frac{21}{260}}[/tex]

The probability of selecting 3 and a consonant is 21/260

(d) Dice

There are 3 even numbers on a die; so the probability of landing on an even number is 3/6

There are 2 numbers less than 3 on a die; so the probability of landing on a number less than 3 is 2/6

So, the probability of landing on an even number and a number less than 3 is:

[tex]\mathbf{Pr = \frac 36 \times \frac 26}[/tex]

[tex]\mathbf{Pr = \frac 16}[/tex]

The probability of landing on an even number and a number less than 3 is 1/6

Your friend claims that the SAS Congruence Theorem (Theorem 5.5) will apply to a triangle and it’s image after the triangle has been translated, reflected, rotated, and dilated. Is your friend correct?

Answers

The triangles would not be congruent since it was dilated.

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Rigid transformation are transformation that preserve the shape and size of the figure. These are rotation, reflection, and translation. Dilation is not a rigid transformation because it reduces or increases the size of the figure.

Two triangles are congruent if they have the same shape and size.

the length of one base of a trapezoid is 7mm less than twice the length of the other base. the height of the trapezoid is 12mm. the area of thr trapezoid is 48mm. find the length in millimeters of the longer base. (please show step by step)

Answers

Answer:

Step-by-step explanation:

let x be the length of one base in mm

The other base will be 2x - 7 mm

I will ASSUME you mean the area is 48 mm²

Area of a trapezoid is the Average base length times height

A = ½(x + (2x - 7))h

A = ½(3x - 7)h

2A/h = 3x - 7

2A/h + 7 = 3x

x = (2A/h + 7)/3

x = 2A/3h + 7/3

x = 2(48)/3(12) + 7/3

x = 5 mm

the other length is

2(5) - 7 = 3 mm
