Twice a number is 14. What is the number .

Answer:

See Explanation

Step-by-step explanation:

Given

[tex]-2 \le x < 5[/tex]

Required

Which is not a solution

The options are not given. So, I will list out the solutions, instead.

We have:

[tex]-2 \le x < 5[/tex]

This implies that: x starts from -2 and ends at 4

[tex]x = \{-2,-1,0,1,2,3,4\}[/tex]

Any number outside the above is not a solution of [tex]-2 \le x < 5[/tex]

Answer:

Step-by-step explanation:

there is a formula for finding distance,

distance = sqrt [ ( x2-x1)^2 + (y2-y1)^2 ]

where point P1 = (-9.-6)  

    in the form of (x1,y1)

and point P2 = (-2,-2)  

 in the form of (x2,y2)

then

distance = sqrt [ (-2-(-9))^2 + (-2-(-6))^2 ]

distance = sqrt [ (-2+9)^2 + (-2+6)^2 ]

distance = sqrt [  [tex]7^{2}[/tex] + [tex]4^{2}[/tex] ]

distance = [tex]\sqrt{65}[/tex]

you can leave it in the form of  [tex]\sqrt{65}[/tex] because that's the most accurate , but also can make a close approximation with  8.062257748

That's all the places my calculators goes out to, the numbers continue thou.

Answer:

Texas Texas Texas is I think right

No, the claim that the three samples are from populations with the same mean is not correct and this can be determined by using the given data.

Given :

The Hypothesis test is given below:

Null Hypothesis: [tex]H_0:\mu_1=\mu_2=\mu_3[/tex]

Alternative Hypothesis: [tex]H_a:\mu_1\neq \mu_2\neq \mu_3[/tex]

For the F-test, the test statistics is given by:

[tex]F = \dfrac{MS_{\rm{between}}}{MS_{\rm{within}}}[/tex]

Now, substitute the values of known terms in the above expression.

[tex]F = \dfrac{15.8252}{0.6896}[/tex]

[tex]F = 22.95[/tex]

So, the p-value regarding the value of F is:

[tex]P-value=P(F>22.95)[/tex]

[tex]P-value = 1.0.9999[/tex]

[tex]P-value = 0.0001[/tex]

The Null Hypothesis is rejected because P-value is less than the significance value.

Answer:

x = 3.96

Step-by-step explanation:

To find the missing side length you'll need the formula a^2 + b^2 = c^2

a and b would be the shorter ends, 2.8 and 2.8

c would be the longer end that's opposite the right angle.

so substitute values

2.8^2 + 2.8^2 = c^2

7.84 + 7.84 = c^2

15.68 = c^2

√15.68 = √c^2

3.959797 = c

c = 3.96

side c would be side x so x is 3.96

Answer:

[tex]55 degree= \frac{\pi }{180}\times55=\frac{11\pi }{36} =0.9599 radians[/tex]

Step-by-step explanation:

[tex]180 degree= \pi radian\\1 degree= \frac{\pi }{180}\\55 degree= \frac{\pi }{180}\times55=\frac{11\pi }{36} =0.9599 radians[/tex]

Step-by-step explanation:

Let the coordinates of point b be (x,y).

Given the coordinates of a (-7,5) and c(5,-1)

Now according to question

ab = 5bc

using distance formula

[tex]\sqrt{(x+7)^2+(y-5)^2} =5\sqrt{(5-x)^2+(-1-y)^2}[/tex]

Solving we can get

[tex]x=-\frac{-11+\sqrt{-4y^2-10y+25}}{2},\:x=\frac{\sqrt{-4y^2-10y+25}+11}{2}[/tex]'

However, we do need either x or y coordinate of point b to find the other.

Answer:

[tex]\frac{3}{5}[/tex]

Step-by-step explanation:

Probability is the chance of an event happening. One finds the probability of an event by using the following general formula,

[tex]\frac{desired}{total}[/tex]

In this case, the desired outcome is pulling whether a red or blue marble from the bag, the desired equals the sum of the number of red and blue marbles.

(red) + (blue)

= 10 + 5

= 15

The total number of marbles is the sum of all the number of marbles in the bag.

(red) + green)  + (yellow) + (blue)

= 10 + 3 + 7 + 5

= 25

Now substitute these values into the formula to find the probability, then simplify,

[tex]\frac{15}{25}[/tex]

Divide both the numerator and denominator by (5),

[tex]\frac{3}{5}[/tex]

Answer:

36/13 (2 10/13)

Step-by-step explanation:

Convert 4 1/2 into an improper fraction: 4 1/2 = 9/2

Convert 1 5/8 to an improper fraction : 1 5/8 = 13/8

Divide: Dividing 2 fractions is the same as multiplying the first fraction by the reciprocal of the second value (the numerator becomes the denominator and the denominator becomes the numerator). 13/8 is 8/13 as a reciprocal. Next multiply the 2 numerators. 9 x 8 = 72. Then multiply the denominators. 2 x 13 = 26. Which gives 72/26. Divide both numbers by 2 which gives 36/13. 36/13 as a mixed number is 2 10/13

Answer:

A. 8100

Step-by-step explanation:

85 x 86

To estimate, we multiply 85*100, which is the easiest multiplication, as a multiplication by 100 is the same as placing two zeros at the end of the number.

85*100 = 8500

Since 86 < 100, 85*86 < 8500. Thus, the correct estimate is given by option A.

Answer:

I think it is -31

Step-by-step explanation:

-4(5) -11 = -31

Answer:

-31

Step-by-step explanation:

First you substitute in 5 for all of the x in the equation, making

f(5) = -4(5) - 11

Then you just have to simplify from there.

f(5) = -20 - 11

f(5) = -31

Answer:

[tex]x = 14[/tex]

[tex]y = -3[/tex]

Step-by-step explanation:

Given

[tex]2x + 8y =4[/tex]

[tex]x = -3y + 5[/tex]

Required

Solve

Substitute [tex]x = -3y + 5[/tex] in [tex]2x + 8y =4[/tex]

[tex]2(-3y + 5) + 8y =4[/tex]

Open bracket

[tex]-6y + 10 + 8y =4[/tex]

Collect like terms

[tex]-6y + 8y =4-10[/tex]

[tex]2y =-6[/tex]

Divide both sides by 2

[tex]y = -3[/tex]

Substitute [tex]y = -3[/tex] in [tex]x = -3y + 5[/tex]

[tex]x = -3 * -3 + 5[/tex]

[tex]x = 9+ 5[/tex]

[tex]x = 14[/tex]

Statement                     Reason

∠1 = ∠2                          Given

AP = BP                          Given

∠APD = ∠BPC                Vertical angles

Therefore, by ASA , ΔAPD ≅ ΔBPC

The top angle is the same as the bottom angle, since they are vertically opposite angles.

b+20=40

b=40-20

b=20

It is also 20 degrees.

Answer:

Step-by-step explanation:

angle b+20 degree=40 degree(being vertically oppoite angles)

angle b=40-20

angle b=20

therefore angle b=20 degree.
