Plz Help Me With My Geometry Asap 50 Pts And Brainliest NO SCAMMING OR I WILL REPORT

Answers

Answer 1

Step-by-step explanation:

1. You already got the first step, where D is the midpoint of AC and AB is congruent to BC, since it's given.

2. AD will be congruent to DC, via the definition of a midpoint (a midpoint is the middle point of a line segment, and it splits the segment into two congruent parts)

3. BD is equal to BD, via reflexive property. ( It's a shared side between the two triangles)

4. that means that ΔADB ≅ΔCDB via SSS rule.

5. ∠ABD ≅∠CDB by CPCTC (corresponding parts of congruent triangles are congruent)

Hope this helps! :)

Answer 2

Answer:

CDB is the longer bottom point so if you want to find the circumference or ≅ you have to find the ratio it would be the points CBD

7/19% of a quantity is equal to what fraction of the​ quantity?

Answers

Answer:

36.84%

Step-by-step explanation:

and 0.3684

7/19% of a quantity expressed as a fraction of the quantity is [tex]\frac{7}{1900}[/tex].

Percentage is the fraction of a quantity expressed as a number out of hundred. For example 1% can be expressed as 1/100

A fraction is a number that consists of a numerator and a denominator. An example of a frication is [tex]\frac{7}{19}[/tex]. 7 is the numerator and 19 is the denominator.

In order to convert a percentage to a fraction, divide the fraction by 100

[tex]\frac{7}{19}[/tex] ÷ 100

= [tex]\frac{7}{19}[/tex] x [tex]\frac{1}{100}[/tex] = [tex]\frac{7}{1900}[/tex]

A bag contains 18 balls to green five black eight blue one brown one red and one white if 17 balls of a move from the bag at random what is the probability that a brown ball has been removed

Answers

Answer:

[tex]P(Brown) = 0.0556[/tex] or [tex]P(Brown) = \frac{1}{18}[/tex]

Step-by-step explanation:

Given

[tex]Total = 18[/tex]

[tex]Green = 2[/tex]

[tex]Black = 5[/tex]

[tex]Blue = 8[/tex]

[tex]Brown = 1[/tex]

[tex]Red = 1[/tex]

[tex]White = 1[/tex]

Required

Determine the probability of selecting a brown ball

This is calculated as thus:

[tex]P(Brown) = \frac{Brown}{Total}[/tex]

Substitute values for Brown and Total

[tex]P(Brown) = \frac{1}{18}[/tex]

The answer can be in fraction or solved further as;

[tex]P(Brown) = 0.0556[/tex]

Tori devotes all of her income to the consumption of peanut butter and jelly. She has just discovered that at her current level of consumption the marginal utility of a jar of peanut butter is 5 and the marginal utility of a jar of jelly is 7. Which statement is TRUE? a. To maximize her total utility, Tori should consume less of both goods. b. To maximize her total utility, Tori should consume more peanut butter and less jelly. c. To maximize her total utility, Tori should consume more of both goods. d. There is not enough information provided to justify a change in Tori's level of consumption.

Answers

the correct answer is option A

To maximize her total utility, Tori should consume less of both goods statement is TRUE. Thus option A is correct.

What is marginal utility?

The additional satisfaction a shopping experience from owning one extra unit of an item or a service is known as marginal utility. Economists utilize the idea of marginal utility to estimate the quantity of a good that buyers will purchase.

Progressive taxation are frequently defended using the law of diminished marginal utility. In the context of consumption, a jar of peanut butter has a marginal utility of 5, while a jar of jelly has a marginal utility of 7.

The purchaser should spend their income so that every penny spent on goods or services results in the same marginal benefit in order to get the most value. Therefore, option A is the correct option.

what does 4^2x-4=1 equal

x=4/2

If the starting equation is

ˣ - 4 = 1

first move the 4 on the left to the right side:

ˣ = 5

Take the base-4 logarithm of both sides:

log₄(4²ˣ ) = log₄(5)

Drop the exponent on the left, using the property [tex]\log_b(a^n)=n\log_b(a)[/tex]:

2x log₄(4) = log₄(5)

Now [tex]\log_b(b)=1[/tex] for any b, so

2x = log₄(5)

Solve for x by dividing both sides by 2:

x = 1/2 log₄(5)

You can also express this as

x = log₄(√5)

to make the solution slightly more compact.

You can also use the change-of-base identity to rewrite the solution as

x = log(5) / (2 log(4))

where the base of the logarithm is arbitrarily chosen. Then

x = log(5) / log(4²)

x = log(5) / log(16)

x = log₁₆(5)

Forty-five percent of households say they would feel secure if they had​ $50,000 in savings. You randomly select 8 households and ask them if they would feel secure if they had​ $50,000 in savings. Find the probability that the number that say they would feel secure is​ (a) exactly​ five, (b) more than​ five, and​ (c) at most five.

Answers

Answer:

0.172 ; 0.0884 ; 0.9115

Step-by-step explanation:

Proportion or those who feel secure, p = 0.45

Sample size, n = 8

Using the binomial distribution formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

A.) p(x = 5)

P(x =5) = 8C5 * 0.45^5 * 0.55^3

P(x = 5) = 56 * 0.0184528125 * 0.166375

P(x = 5) = 0.1719248540625

P(x = 5) = 0.172

B.) P(x > 5)

P(x > 5) = P(x = 6) + P(x = 7) + P(x = 8)

P(x > 5) = 0.0703 + 0.0164 + 0.0017

P(x > 5) = 0.0884

C.) P( ≤ 5) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3) + P(x = 4) + P(x = 5)

Using the binomial probability calculator to obtain a direct solution :

P( ≤ 5) = 0.9115

Look at this set of ordered pairs:
(3, -13)
(3, 2)
(18,-5)
Is this relation a function?
yes
no

Answers

Answer:

No

Step-by-step explanation:

Given ordered pairs:

(3, -13) (3, 2) (18,-5)

There is a repeat of domains (3) with different range (-13 and 2) but the function can't have repeat domains so it is not a function

Answer:

It would not be a function

Step-by-step explanation:

A function has no repeating 'x' values

(3,-13) x=3

(3,2) x=3

(18,-5)  x=18

So, because there is more than one of the same 'x' value (3) it is not a function.

John states that the products of two real numbers is a real number. Extending this to imaginary numbers. John states that the product of two imaginary numbers must be imaginary. Is his statement correct? Explain

No, this is a wrong statement.

In the context, it is given that John states that the product of two the real numbers provides a number that is real. This is always true, the product is always a real number of two real number.

But the product of any two imaginary numbers is not a imaginary number, the product is always a real number.

Answer:

Solving the inequality [tex]3x -2 < 4[/tex] we get [tex]\mathbf{x<2}[/tex]

Option D is correct option.

Step-by-step explanation:

We need to solve the inequality [tex]3x -2 < 4[/tex] and find value of x

Solving the inequality for finding value of x, we will keep x on left side of inequality and all other terms on the right side.

[tex]3x -2 < 4[/tex]

Adding 2 on both sides

[tex]3x -2+2 < 4+2\\3x < 6[/tex]

Now, we will divide 3 on both sides

[tex]\frac{3x}{3}<\frac{6}{3}\\x<2[/tex]

So, we get x < 2

Solving the inequality [tex]3x -2 < 4[/tex] we get [tex]\mathbf{x<2}[/tex]

Option D is correct option.
