Dmitrij [34]

Answer:

-5

Step-by-step explanation:

y- 1/5x = 7

y= 1/5x +7

So, the slope of the line is 1/5

Perpendicular slopes are always the reciprocal with an inverse sign.

So, -5

Jada has a bag with tiles she pulls a tile from the bag without looking accords the shape and then puts the tile back in the bag
vova2212 [387]

What is the probablity for the number of times Jada will pull a tile wit a star?

Answer: Number of tiles pulled out of the bag by Jada = 10, so she completed 10 trials.

The outcome of each trial was star, circle or a square.

Step-by-step explanation: We can find the experimental probability of pulling each shape from the bag based on the outcomes of Jada's experiment and number of trial.

  1. P(Star) = Number of stars/Number of trials= 5/10
  2. P(Circles)= Number of circles/Number of trials =3/10
  3. P(Square) = Number of Square/Number of trials = 2/10
    Here, P refers to Probability of an outcome

If Jada repeats the experiment, She would likely again pull more stars than circles or square. She may get different number of stars,circles or squares but over a large number of trials, she would expect the ratio of the stars in the proportion. We can use this proportonal relationship to get the reasonable prediction about te number of times she pull different shape tiles.

<u>Number of outcomes(10 trials) </u> = <u>Number of outcomes(100 trials)</u>

Number of trials(10 trials)              Number of trials (100 trials)

  1. Numbeof stars = 5/10 =s/100
    5*10/ 10*10 =50/100
  2. Number of Circle = 3/10 = c/100
    3*10/10*10 = 30/100
  3. Number of square = 2/10 = q/100
    2*10/10*10 = 20/100

    If she does the experiment 100 times then she should expect to pull out 50 stars tile, 30 circles and 20 Square.

Hence, Jada pulled out the 100 tiles from the bag.

Study the example on the right to help you complete the problem below. please help!:(
Inga [223]

Answer : The equation for 'h' is h=\frac{2A}{b}

Step-by-step explanation :

The given equation is:

A=\frac{1}{2}bh

Now we have to determine the equation for 'h'.

A=\frac{1}{2}bh

Multiplying the equation by 2.

2\times A=2\times \frac{1}{2}\times bh

on simplifying, we get:

2\times A=bh

Dividing the equation by 'b'.

\frac{2\times A}{b}=\frac{bh}{b}

\frac{2\times A}{b}=h

or,

h=\frac{2A}{b}

Therefore, the equation for 'h' is h=\frac{2A}{b}

2 Evaluate the following expression when x = 2. x3 + 7x + 2
bogdanovich [222]

Answer:

B

Step-by-step explanation:

Since x is 2 wherever you see x put 2

solve x3 + x7+ 2

=(2)3 + (2)7 + 2

= you do the number outside the bracket multiplied by the number inside the bracket

like this

=(2 × 3) + (2 × 7) + 2

= 6+ 14 + 2

= 22
