Answer:

2 7/18

Step-by-step explanation:

Follow the pemdas order of operations, apply the + (-a) = a Rule. Add and subract from left to right. 5/6 - 4/9 = 7/18 with 2 and it gives you your answer but keep in mind the two multiples are 6,9. Hope this helps!

Answer:

The sample size is  [tex]n =  841 [/tex]

Step-by-step explanation:

From the question we are that

    The standard deviation is  [tex]\sigma = 5.6 \ hours[/tex]

     The margin of error is  [tex]E = 0.45[/tex]

From the question we are told the confidence level is  98% , hence the level of significance is    

      [tex]\alpha = (100 - 98) \%[/tex]

=>   [tex]\alpha = 0.02[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  2.33[/tex]

Generally the sample size is mathematically represented as  

   [tex]n = [\frac{Z_{\frac{\alpha }{2} } *  \sigma }{E} ] ^2[/tex]

=>   [tex]n = [2.33 } *  5.6}{0.45} ] ^2[/tex]

=>   [tex]n =  841 [/tex]

Year | Precipitation (Inches)

2015 | 44.83

2016 | 45.18

2017 | 47.87

2018 | 35.73

2019 | 33.88

For the relationship just determine the pattern if it is addition subtraction e.t.c

Ex. The relationship is +30 or -56

Last but not least determine if it is a function pretty simple

And for my effort please name me the brainliest I really need Thank u

Answer/Step-by-step explanation:

3. Function: NO

Justification: there will be more than one y-value/output related to one x-value/input.

4. Function: YES

Justification: There are exactly one y-value/output related to each input/x-value in the relation.

5. Function: YES

Justification: each x-value/input is mapped to exactly one y-value/output. No input value is mapped to more than one output value.

Answer:

y = - [tex]\frac{1}{4}[/tex] x + [tex]\frac{9}{4}[/tex]  

Step-by-step explanation:

(-3, 3)

2y = 8x - 6 ⇔ y = 4x - 3

y - 3 = - [tex]\frac{1}{4}[/tex] (x + 3)

y = - [tex]\frac{1}{4}[/tex] x + [tex]\frac{9}{4}[/tex]

Answer:

The domain (x values) is negative infinity to positive infinity since the graph keeps going in both directions ( left and right ) and the range (y values) is -1 to positive infinity since the graph starts at vertex (-1, -4) and continues infinitely upward.

Answer:

The equilibrium quantity is 26.4

Step-by-step explanation:

Given

[tex]Q_d = 48 - 9P[/tex]

[tex]Q_s = 12 + 6P[/tex]

Required

Determine the equilibrium quantity

First, we need to determine the equilibrium by equating Qd to Qs

i.e.

[tex]Q_d = Q_s[/tex]

This gives:

[tex]48 -9P = 12 + 6P[/tex]

Collect Like Terms

[tex]-9P - 6P = 12 - 48[/tex]

[tex]-15P = -36[/tex]

Solve for P

[tex]P = \frac{-36}{-15}[/tex]

[tex]P =2.4[/tex]

This is the equilibrium price.

Substitute 2.4 for P in any of the quantity functions to give the equilibrium quantity:

[tex]Q_d = 48 - 9P[/tex]

[tex]Q_d = 48 - 9 * 2.4[/tex]

[tex]Q_d = 26.4[/tex]

Hence, the equilibrium quantity is 26.4

Answer:

√10

Step-by-step explanation:

Pythagorean theorem. a^2+b^2=c^2.

In this case 9^2+b^2=√91^2. That equals 81+b^2=91. You isolate b^2, b^2=10. So b=√10.

Step-by-step explanation:

Answer:

x = -47, y = 39

Step-by-step explanation:

2x+3y=23 →equation 1

3x+4y=15 →equation 2

by elimination method,

(2x+3y=23) × 4

(3x+4y=15) × 3

8x + 12y = 92

(-)      (-)       (-)

9x + 12y = 45

---------------------

-1x + 0    = 47

-x = 47

x = -47

substitute x=-47 in equation 1

2(-47) + 3y = 23

-94 + 3y = 23

3y = 23 + 94

3y = 117

y = 117/3

y = 39

therefore, x = -47 and y = 39

hope you understood ❤❤❤

Answer:

y = x + 7

Step-by-step explanation:

The equation of a line in slope - intercept form is expressed as y = mx+c

m is the slope

c is the intercept

Get the slope m;

m = tan theta

m = tan 45

m = 1

Get the intercept c;

Substitute m = 1 and (-2, 5) into the equation y = mx+c and get c;

5 = 1(-2)+c

5 = -2+c

c = 5+2

c = 7

Get the required equation;

y = 1(x)+ 7

y = x + 7

Hence the equation of the line is y = x+7

Complete question :

Find the standardized test statistic t for a sample with n = 15, x = 10, s = 0.8, H0: μ = 10.5. Round your answer to three decimal places.

Answer:

−2.420614

Step-by-step explanation:

Given that:

Given that:

n = 10

s = 0.8

X = 15

μ = 15.9

Using the relation :

(x - μ) / (s/√n)

(10 - 10.5) / (0.8/√15)

-0.9 / 0.2065591

= −2.420614

Hence, the standardized test statistic = −2.420614
