A local little league has a total of 65 players, of whom 20% are right-handed. How many
right-handed players are there?

Answer:

-0.880

Step-by-step explanation:

Mean X = 56.7

Sd = 30

N = sample size = 64

Null hypothesis:

H0:u = 60

Alternative hypothesis:

H1:u not equal to 60

This corresponds to a 2 tailed test. So we will have to use a z test with 1 mean, known population and standard deviation

Level of significance = 0.05

Z critical value = 1.96

The test statistic

Z = X - u/sd/√n

= 56.7 - 60/30√64

= -0.880

The test statistic is equal to -0.880

Answer:

18 Daisies and 12 Carnations

Step-by-step explanation:

The total amount of flowers adds to be 30 therefore the amount of daises plus the amount of carnations should equal 30 (d+c=30). Then your ratio of daises to carnations is 3 to 2. Which means that you are going to have three daisies for every 2 carnations.

Answer:

m<C = 119°

Step-by-step explanation:

Create an equation to find the value of x.

(9x - 26)° = (2x - 12)° + (4x + 43)° (exterior angle theorem of a ∆)

Solve for x

9x - 26 = 2x - 12 + 4x + 43

Add like terms

9x - 26 = 6x + 31

9x - 6x = 26 + 31

3x = 57

Divide both sides by 3

x = 19

✔️m<C = 4x + 43

Plug in the value of x

m<C = 4(19) + 43

m<C = 76 + 43

m<C = 119°

the answer is 0.74 not 0.074

Step-by-step explanation:

Answer:

number 1 is D

number 2 is distribute 2 into x and 14(multiplying)  getting 2x+28=40

then subtract 28 from each side  40-28=12  after just simply divide 2x by its self and into 12 getting 6

number 3 is 12

number 4 is subtract 2 from both side

number 5 is divide

number 6 is 6

I hope this helps have a great day!

Answer:

I suggest you use Socratic, it solves questions like this.

Step-by-step explanation:

Answer:   or (1,1)

Step-by-step explanation:

You can apply the Method of substitution.

Knowing that   (second equation), you can substitute it into the first equation and solve for the variable y:

Now you need to substitute  into the second equation  to calculate the value of the variable x. Then:

Then, the solution is:

or (1,1)

Answer: This is true because everything in the first equation was multiplied equally to get to the second equation. Every part was multiplied by three. The first equation is x-7=3 and the second can be seen as 3(x-7=3). The three will not affect x seeing that the entire equation had the same thing done to it.

Step-by-step explanation:

There can be only 1 triangle formed by the given information.

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices. A triangle is also a polygon.

Given that, ABC can be formed if C=60∘, c=17√3 and a=34

Using the sine law for triangle,

A/sina = B/sinb = C/sinc

34/sina = 17√3/sin60°

⇒ sina = 90°

Since, The triangle ABC is a right triangle,

Hence, There can be only 1 triangle formed by the given information.

Answer:

x=67

Step-by-step explanation:

Two ways to solve it:

1st way: Just looking at it, x is definitely not 180° because it’s to big of an angle, it is definitely not 113° because it’s still to big of an angle, and it’s also not 90° because it doesn’t form a right angle. So it must be 67°.

2nd way: Since two angles in a straight line add up to 180°, you can subtract 113° from 180° to find what x is. You can tell that 180° - 113° is equal to 67°

So either way, the answer is: x=67

Given value:

[tex]\to \mu= 711\\\\\to \sigma= 80\\\\\to P(Z >0.84) = 0.20\\\\\to z = 0.84[/tex]

The formula for z-score:
