Step-by-step explanation:

Note is seems typo, b = 0

Given, expression

It represents distributive property of multiplication a(b + c) = ab + ac

Correct choice is the first one

Part A: A Type II error in this context is failing to reject the null hypothesis that 25% of parents with hearing impaired children have the ability to pass a sign-language exam when actually less than 25% are able to pass it.

Part B: We fail to reject the null hypothesis because the p-value of 0.96 is larger than α = 0.05. The evidence is not substantial that the proportion of parents with hearing impaired children in Clover City who are able to pass a sign language exam is less than 0.25. The sample proportion of phat = 0.96 is greater than 0.25.

Part C: The sample of 175 parents with hearing impaired children in Clover City was a group of volunteers, so most likely they were confident in their ability to pass a sign language exam which could better the chances of more passing sign language exams.

Answer:

  D.  obtuse

Step-by-step explanation:

The largest angle tells you the sort of triangle it is. Here, the largest angle is more than 90°, so the triangle is classified as obtuse.

__

If it were exactly 90°, the triangle would be a right triangle. A largest angle less than 90° means the triangle is an acute triangle.

_____

Additional comment

The two angles opposite the obtuse angle have the same measure. That means the triangle can be further classified as isosceles. In an equilateral triangle, all three angles have the same measure: 60°.

Answer: 90%

Step-by-step explanation: Well let us look at it together let’s make a small example, We know that 20 out of 40 would be 50 percent because it’s half. While using this info we can find out that...

1 out of 40 would be 2.5 percent.

2.5 percent times 14.4 = 36 percent.

36 percent of 40 = 90%

Answer:

4.6% (nearest tenth)

Step-by-step explanation:

percent error = (|approx - actual| ÷ actual) × 100

percent error = (|16 - 15.3| ÷ 15.3) × 100

                      = 4.6% (nearest tenth)

[tex] \sf\% \: error = \frac{ |approx - actual| }{actual} \times 100[/tex]

[tex] \tt\% \: error = \frac{ |16 - 15.3| }{15.3} \times 100[/tex]

[tex] \tt\% \: error = \frac{ |0.7| }{15.3} \times 100[/tex]

[tex] \tt\% \: error = \frac{ |0.7| }{ \frac{153}{10} } \times 100[/tex]

[tex] \tt\% \: error = \frac{0.7}{ \frac{153}{10} } \times 100[/tex]

[tex] \tt\% \: error = \frac{ \frac{7}{10} }{ \frac{153}{10} } \times 100[/tex]

[tex] \tt\% \: error = \frac{7 }{ 153 } \times 100[/tex]

[tex] \tt\% \: error = \frac{7 00}{ 153 } [/tex]

Step-by-step explanation:

when graphed, x=1 goes up and down which makes it's slope undefined

Answer:

(infinity)

Step-by-step explanation:

rate of change for the equation x = 1

use the formula: y = mx + b

where:

y = how far up the line goes

m = slope

x = how far along

b = Y-intercept

the equation is a vertical line,

so the slope = ∞ (infinity)

Answer:

B

Step-by-step explanation:

sin = opp/hyp

The opposite side to angle A is side BC, which has a length of 60.

The hypotenuse is AB, which we can find the length of using the Pythagorean theorem. Using the Pythagorean theorem, we get that AB=100.

So the sine of A = 60/100 = 3/5

Answer:

y = 2

Step-by-step explanation:

We are given the value of x (second equation). Let's substitute the value of x into the first equation to find y.

[tex]\rightarrow \dfrac{x}{y} = 6[/tex]

[tex]\rightarrow \dfrac{4(y + 1)}{y} = 6 \ \ \ \ \ \ \ \ \ \ \ \ \ \text{\large{[}x = 4(y + 1)]}[/tex]

Use cross multiplication.

[tex]\rightarrow 4(y + 1) = 6 \times y[/tex]

[tex]\rightarrow 4(y + 1) = 6 y[/tex]

Simplify the distributive property.

[tex]\rightarrow 4(y + 1) = 6 y[/tex]

[tex]\rightarrow 4y + 4 = 6 y[/tex]

Subtract 4y both sides.

[tex]\rightarrow 4y - 4y + 4 = 6 y - 4y[/tex]

[tex]\rightarrow 4 = 2y[/tex]

Divide both sides by 2.

[tex]\rightarrow \dfrac{4}{2} = \dfrac{2y}{2}[/tex]

[tex]\rightarrow 2 = y[/tex]

Thus, the value of y is 2.

spicifically 5/3

The x satisfy only 1 value and x is  [tex]\frac{5}{3}[/tex]   .

The modulus function, which is also called the absolute value function gives the magnitude or absolute value of a number irrespective of the number being positive or negative. It always gives a non-negative value of any number or variable. Modulus function is denoted as y = |x| or f(x) = |x|, where f: R → (0,∞) and x ∈ R.

According to the question

-2|3x-5|=0  

Step1: Dividing -2 both side

|3x-5|=0  

Step 2: Open modulus

3x-5=0      and        - 3x+5=0

3x=5         and         - 3x = - 5

x = [tex]\frac{5}{3}[/tex]    

Hence, the x satisfy only 1 value and x is  [tex]\frac{5}{3}[/tex]   .

Answer:

≤ 4.3 gigabytes

Step-by-step explanation:

Flat fee + cost for x gigabytes = her budget

47 + 5 * x ≤ 68.50

5x = 68.50 - 47 ≤ 21.50

x ≤ 21.50/5 = 4.3 gigabytes

Micaela can use approximately 4.3 gigabytes of data while staying within her budget of $68.50 per month.

Let, "x" to represent the number of gigabytes of data Micaela can use while staying within her budget.

The total cost can be calculated by adding the flat cost of $47 to the cost based on the gigabytes used ($5 per gigabyte):

Total Cost = Flat Cost + (Cost per Gigabyte * Number of Gigabytes)

Given that Micaela wants to keep her bill at $68.50 per month, we can set up the equation:

68.50 = 47 + 5x

Now, solve for x:

68.50 - 47 = 5x

21.50 = 5x

Divide both sides by 5:

x = 21.50 / 5

x = 4.3

So, Micaela can use approximately 4.3 gigabytes of data while staying within her budget of $68.50 per month.

Answer:

A

Step-by-step explanation:

A function is a relation for which each value from the set the first components of the ordered pairs is associated with exactly one value from the set of second components of the ordered pair.

Answer:

x^(2)+(y+2)^(2)=1

Step-by-step explanation:

Part (a)

This sequence is convergent because all we care about are the leading terms for the numerator and denominator. As n gets really large, the leading terms dictate what happens.

The leading term up top is 9n

The leading term down below is 7n

Divide the two items to get (9n)/(7n) = 9/7

We don't have to worry about dividing by zero because n will go off to infinity, and as it does so, the sequence [tex]\{a_n\}[/tex] converges to 9/7

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

Part (b)

As n heads to infinity, the terms of the sequence are approaching 9/7 (they never quite hit the exact value though).

Note how 9/7 = 1.2857 approximately which is larger than 0

So effectively for very large values of n, we're adding on 1.2857 each time or close to it, meaning that this infinite series diverges.

------

For a series like this to converge, the answer to part (a) must be 0. This way at some point, we're effectively adding 0 to the series and we approach some fixed sum.

For example, consider the sequence 1/(7n+1)

As n goes to infinity, the terms of the sequence approach 0

This means that for some very large n, the 1/(7n+1) is basically 0 and we aren't adding much onto the sum to change it. So this sum will converge to a fixed value.

to know what scale to use you divide the the highest score by the number of hozirontal line (feint/lighter drawn lines) which are 14.

so 260 ÷ 14 equals = 18.57

I then rounded the 18.57 to the nearest 10th = 20.

so the scale used is 20s

Answer:

x+14=21 Add 14 to both sides of the equation. Subtract 14 from the left side of the equation. Add 14 to the left side and subtract 14 from the right side of the equation.
