Can y’all please help me

Answer:

Step-by-step explanation:

using supplementary angles we can fine that two angles of a straight line =180

128+?=180 ?=180-128=52

126+?=180 ?=180-126=54

all angles of a triangle add up to 180 degrees

180=52+54+?

94=?

180-94=x

106=x

Answer:

Mutual funds differ from CDs in a multitude of ways. Mutual funds are diversified portfolios of stocks and bonds managed by a financial advisor or broker. They typically offer substantially higher returns than CDs, and while they are riskier than CDs, they are not considered high risk investments.

Concept: Arithmetic Sequence & Series

The solution is, the correct formula for the following Arithmetic Sequence:  -4, -1, 2, 5, 8,…, is, an = -4 + 3(n – 1), the value of the n-th term.

We know that,

from Arithmetic Sequence & Series we get,

The nth term of AP : a_n = a + (n – 1) × d

where, a = first term

d = common difference,

Notice the change is +3 for the first iteration and then +3 for the second iteration and so on

i.e. here,

a = -4

d = +3

Hence it must work for any nth variable.

So we have -4+3(n-1)

Hence, we get, an = -4 + 3(n – 1).

Answer:

The statements that are true about a hypothesis test for two proportions are:

I. It estimates the common value of p1 and p2 under the assumption of equal proportions.

II. It is obtained by averaging the two sample proportions 1 and 2.

Step-by-step explanation:

We use the two sample proportion z-test to determine whether the proportions of the two groups differ. This test calculates the range of values that is likely to include the differences between the sample proportions of p1 and p2.

Answer:

no

Step-by-step explanation:

here, f (x)=x^3 - 4x^2 + 3x + 7

when, factor is (x + 5)

x - a =x + 5

a = -5

Reminder= f (a)

= (-5)^3 - 4 (-5)^2 + 3×(-5) + 7

= -233

Since Reminder = -233 which is not 0 .

(x + 5) is not a factor of f (x)=x3-4x2+3x+7

Answer:

128

Step-by-step explanation:

Sam has X stamps.

Jill has (576-X) Stamps.

X-x/7 = 6x/7 = Sam's bal.

576-x + x/7 = 576 - 6x/7 = Jill's bal.

1/4(576-6x/7) = 144 - 6x/28

3/4(576-6x/7) = 432 - 9x/14 = Jill's new

bal.

6x/7 + 144-6x/28 = 144 + 24x/28-6x/28 =

144 + 9x/14 = Sam's new bal.

Jill's new bal = Sam's new bal

432 - 9x/14 = 144 + 9x/14

18x/14 = 144-432 = 288

18x = 4032

X = 224

576-X = 576-224 = 352.

Difference = 352 - 224= 128

Answer:

C.) 6

Step-by-step explanation:

I multiplied the number 2 by X and my sum was Y.

Answer:

Let's solve for a.

2(3x+4)=ax+b

Step 1: Flip the equation.

ax+b=6x+8

Step 2: Add -b to both sides.

ax+b+−b=6x+8+−b

ax=−b+6x+8

Step 3: Divide both sides by x.

ax

=

−b+6x+8

Answer:

c) is the correct answer

Step-by-step explanation:

Answer:

91.08%

Step-by-step explanation:

Confidence interval = (1.6, 8.4)

Sample size (n) = 30

Standard Error (E) = 2

Mean (m) = 5

The confidence interval is obtained using the relation :

Mean ± Zcritical * standard error

5 ± Zcritical * 2

5 - (Zcritical * 2) = 1.6

5 - 2Zcritical = 1.6

5 - 1.6 = 2Zcritical

3.4 = 2Zcritical

Zcritical = 3.4 / 2

Zcritical = 1.7

From Z probability calculator

P(Z < 1.7) = 0.044565

α = 1 - (0.044565 * 2) = 0.91087

0.91087 * 100% = 91.08% = 91%

Hence, confidence level = 91.08%

Yes, always.

Answer:

The system of equations is given as:

x ≥ $500

y ≥ $800

x + y ≤ 1600

20x + 30y ≥ 2800

Step-by-step explanation:

From the question

We are told that

x = Number of $20 seats

y = Number of $30 seats

$20 seats = At least $500 (greater than or equal to)

$30 seats = At least $800 (greater than or equal to)

You are designing a social hall that would seat no more than 1600 people

No more than means less than or equal to ≤ 1600 people

x + y ≤ 1600 people

Total revenue generated = At least $2800. This means ≥ (greater than or equal to).

20x + 30y ≥ $2800

The system of equations is given as:

x ≥ $500

y ≥ $800

x + y ≤ 1600

20x + 30y ≥ 2800

Option C is the correct Option.

Answer:

B. Function F is odd

Step-by-step explanation:

If a function is odd, then -f(x) = f(-x), for all values of x.

For such function an origin symmetry is obtained just like the image uploaded.

Also, for such function, there is an equal distance between f(x) and f(-x), just like the image uploaded (d₁ = d₂).

Thus, the correct option is "B"
