Answer:

is it - 4(3a+b)    ?

Step-by-step explanation:

Answer: b

Step-by-step explanation:

you start with 0 min- equals 24

1 min- 21

2 min- 18

3 min- 15

4 min- 12

5 min- 9

and so on- you look for the table that best describes that. x represents the minutes, and y represent the amount of water left in the sink.

Answer:

B

Step-by-step explanation:

After the first minute it should be at 21, because it would be reduced by 3. Second, the same. ETC

Answer:

C) y is greater than or equal to 1

a direct variation is when the two numbers increase or decrease but they still vary together

Answer:

B

Step-by-step explanation:

"at least 50" includes 50 as a possibility, which means it would be [tex]p\geq 50[/tex]

Answer:

16 people haven't replied

Step-by-step explanation:

Add 9 + 8 = 17 and subtract 33 - 17 = 16

If this helps

The guests (g) still need to reply are 16.

Arithmetic operation is an elementary part of mathematics that consists of the study of the properties of the traditional operations on numbers—addition, subtraction, multiplication, division, exponentiation, and extraction of roots.

Now it is given that,

Number of guests invited = 33

Number of guests replied "will attend" = 8

Number of guests replied "will not attend" = 9

So, total guest replied = 8 + 9

⇒ total guest replied = 17

Thus, the guests (g) still need to reply = 33 - 17

⇒ the guests (g) still need to reply = 16

Thus, the guests (g) still need to reply are 16.

Answer:

x = 1,650

Step-by-step explanation:

A real-world problem with a sample and a population is modeled by the proportion 66/100=x/2,500. Use the proportion to complete the sentences.

From the above question, we have to solve for x

Hence, we have the proportion

66/100=x/2,500

Cross Multiply

100 × x = 66 × 2,500

x = 66 × 2,500/100

x = 1,650

Answer:

4-2=2

Step-by-step explanation:

since they are on the same quadrant you we subtract.

Step-by-step explanation:

yx = 2

if x = 7

y(7) = 2

y = 2/7

yx = 2

if y = 2

2(x) = 2

x = 1

Answer:

So the formula of area of the circle A=πr2. The answer is 153.86.

Step-by-step explanation:

You first divide 14/2=7 then do 7^2 which equals 49 lastly multiplying 3.14 X 49. So how is the radius 7 because half of a diameter is a radius.Therfore the answer is 153.86.

Answer:

b

Step-by-step explanation:

(x⁴ -11x² + 30)(x +2) = (x⁴ -11x² + 30)*x + (x⁴ -11x² + 30)*2

                               = x⁴*x - 11x²*x + 30*x + x⁴*2 - 11x²*2 + 30*2

                               =x⁵ - 11x³ + 30x + 2x⁴ - 22x² + 60

                               = x⁵ + 2x⁴ - 11x³ - 22x² + 30x + 60

Answer:

[tex]\frac{55}{14}[/tex]

Step-by-step explanation:

First, we convert the mixed numbers into improper fractions: [tex]1\frac{3}{7} =\frac{10}{7}[/tex], and [tex]2\frac{3}{4}=\frac{11}{4}[/tex]. Now, we multiply the fraction using the multiplication rule, [tex]\frac{a}{b} \times \frac{c}{d} = \frac{a \times c}{b \times d}[/tex]: [tex]\frac{10}{7} \times \frac{11}{4} = \frac{110}{28} = \frac{55}{14}[/tex].

Thus, the product of the two given fractions is 55/14.

D (No, because there are values in the interval that are greater than 0.85.)

Step-by-step explanation:

edge2021 :)

The true proportion of times this weather forecaster correctly predicts the weather is less than 85% are; No, because there are values in the interval that are greater than 0.85.

Suppose we're given that:

Favourable Cases X (in count, in sample)

Sample Size N

Level of significance =[tex]\alpha[/tex]

Then, the sample proportion of favorable cases is:

[tex]\hat{p} = \dfrac{X}{N}[/tex]

The critical value at the level of significance [tex]\alpha[/tex] is [tex]Z_{1- \alpha/2}[/tex]

The true proportion of times this weather forecaster correctly predicts the weather is less than 85% are given as;

IT is No, because there are values in the interval that are greater than 0.85.
