Answer:

  I'(1, -4)

Step-by-step explanation:

The transformation for rotation 90° about the origin is ...

  (x, y) ⇒ (-y, x)

  I(-4, -1) ⇒ I'(1, -4)

Answer:

x = 14

Step-by-step explanation:

Given that,

2:7 is expressed in the form for 4:x.

We need to find the value of x.

2:7 must be equated to 4:x.

So,

[tex]2:7=4:x\\\\or\\\\\dfrac{2}{7}=\dfrac{4}{x}\\\\x=\dfrac{7\times 4}{2}\\\\x=14[/tex]

So, the value of x is equal to 14.

Answer:

0.2088 = 20.88% probability that Jackson randomly selects a person from this population who recalls between 26 and 29 memories.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Population mean of 30 and a population standard deviation of 5.

This means that [tex]\mu = 30, \sigma = 5[/tex]

What is the probability that Jackson randomly selects a person from this population who recalls between 26 and 29 memories?

This is the pvalue of Z when X = 29 subtracted by the pvalue of Z when X = 26. So

X = 29

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{29 - 30}{5}[/tex]

[tex]Z = -0.2[/tex]

[tex]Z = -0.2[/tex] has a pvalue of 0.4207

X = 26

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{26 - 30}{5}[/tex]

[tex]Z = -0.8[/tex]

[tex]Z = -0.8[/tex] has a pvalue of 0.2119

0.4207 - 0.2119 = 0.2088

0.2088 = 20.88% probability that Jackson randomly selects a person from this population who recalls between 26 and 29 memories.

Answer:

it is this one

Step-by-step explanation:

because since x is 4 and y is 8 that one matches up better than any other one

Answer:

x = 7

z = 85

Step-by-step explanation:

For x:

8x + 39 = 95

8x = 56

x = 7

For z:

95 + 95 + z + z = 360

190 + 2z = 360

2z = 170

z = 85

Check work:

DOES 85 + 85 + 95 + 95 = 360 ? Yes. Answer is correct.

Answer: your mom gay ;)

Step-by-step explanation:

4,500 calories a day

If you ate the same amount each day, that means you would eat 3 a day, since 6 divided by 2 is 3.

Find how many calories you would eat each day by multiplying 3 by 1,500

3(1,500)

= 4500

Answer:

-3

Step-by-step explanation:

-4a - 2a - 7 = 11

-6a - 7 = 11                                      Combine coefficients.

      +7   +7

-6a = 18                                           Isolate the variable.

a  = -3                                 Divided by 6 on both sides to isolate the variable.

Answer: 1,431

Step-by-step explanation:

split the thing into two rectangular prisms

small prism dimensions: 18 x 2 x 3

multiply the dimensions to get 108

large prism dimensions: 7 x 21 x 9

multiply the dimensions to get 1,323

add 1,323 and 108 together to get 1,431

Answer:

a) True

     [tex]\int\limits^\pi _ {0} \,(\sqrt{1-sin^{2}\alpha } )d\alpha =0[/tex]

Step-by-step explanation:

Step(i):-

Given that the definite integration

           [tex]\int\limits^\pi _ {0} \,(\sqrt{1-sin^{2}\alpha } )d\alpha[/tex]

we know that the trigonometric formula

sin²∝+cos²∝ = 1

           cos²∝ = 1-sin²∝

step(ii):-

Now the  integration

        [tex]\int\limits^\pi _ {0} \,(\sqrt{1-sin^{2}\alpha } )d\alpha = \int\limits^\pi _0 {(\sqrt{cos^{2} \alpha } } \, )d\alpha[/tex]

                                     = [tex]\int\limits^\pi _0 {cos\alpha } \, dx[/tex]

Now, Integrating

                                 [tex]= ( sin\alpha )_{0} ^{\pi }[/tex]

                               = sin π - sin 0

                              = 0-0

                             = 0

Final answer:-

     [tex]\int\limits^\pi _ {0} \,(\sqrt{1-sin^{2}\alpha } )d\alpha =0[/tex]

Answer:

  $850

Step-by-step explanation:

The amount of interest earned is ...

  I = Prt . . . . . on principal P at annual rate r for t years

Using the given values, the interest earned is ...

  I = $2000·0.0425·10 = $850

The interest Rozlyn's account earns in 10 years is $850.

Answer:

$4031.75

Step-by-step explanation:

   A = P(1+r/n)^nt       P = 3000    n semi-annually = 2       rate = 0.06    t = 5

      =  3000(1+0.06/2)^((2)(5))

      =  3000 ( 1+ 0.03)^10

      =  3000(1.03)^10            use calculator now

-0.3*0.2*12, multiply -0.3 by 0.2 to get -0.06, now multiply 12 by it to get, -0.72.

Step-by-step explanation:

Answer:

279

Step-by-step explanation:

First, you plug in 500 for " x " because it says P( 500 ).

P( 500 ) = 0.75 (500) -96

Then, you multiply / simplify

P ( 500 ) = (375) - 96

P ( 500 ) = 279

Finally, it gives you your answer for selling 500 pretzels
