Kenny’s weight is 6/7 times Melvin’s weight.

Mathematics
1 answer:
Mazyrski [523]3 years ago
3 0

Answer=7:13


Kenny's Weight*6/7=Melvin's Weight


So, for example, if Melvin's weigh was 7...


Kenny's Weight*6/7=7

divide both sides by 6/7

Kenny Weight=6


So we can say that Melvin's weight to Kenny's weight is 7:6


The boys total weights would be...

7+6=13



So Melvin's weight over the total weight of the two boys is:


7:13

gtnhenbr [62]

Answer:

99\% CI=4.1602 \pm 0.0009

Step-by-step explanation:

From the question we are told that:

Sample size n=8

Mean \=x=4.1602

Standard deviation \sigma=0.001gram

Generally 99\% confidence from table  is mathematically given by

 99\% CI=4.1602 \pm *2.576*\frac{0.001}{\sqrt{{8}}}

 P(-z

 Z_{\alpha/2}=2.576

Generally the equation for 99\% confidence level (CI)  is mathematically given by

 99\% CI=\=x \pm Z_{\alpha/2*\frac{\sigma}{\sqrt{{n}}}

 99\% CI=4.1602 \pm 0.0009

Solve the system. 2x + y = 3 −2y = 14 − 6x Write each equation in slope-intercept form.
barxatty [35]

Answer:

2x + y = 3

y = -2x + 3 <==

-2y = 14 - 6x

y = -14/2 + 6/2x

y = -7 + 3x

y = 3x - 7 <===

Find the y intercepts of 3x^2+24x-51. quadratic formula
julia-pushkina [17]
  • Quadratic Formula: x=\frac{-b\pm \sqrt{b^2-4ac}}{2a} , with a = x^2 coefficient, b = x coefficient, and c = constant.

Firstly, starting with the y-intercept. To find the y-intercept, set the x variable to zero and solve as such:

y=3*0^2+24*0-51\\y=0+0-51\\y=-51

<u>Your y-intercept is (0,-51).</u>

Next, using our equation plug the appropriate values into the quadratic formula:

x=\frac{-24\pm \sqrt{24^2-4*3*(-54)}}{2*3}

Next, solve the multiplications and exponent:

x=\frac{-24\pm \sqrt{576-(-648)}}{6}\\\\x=\frac{-24\pm \sqrt{576+648}}{6}

Next, solve the addition:

x=\frac{-24\pm \sqrt{1224}}{6}

Now, simplify the radical using the product rule of radicals as such:

  • Product Rule of Radicals: √ab = √a × √b

√1224 = √12 × √102 = √2 × √6 × √6 × √17 = 6 × √2 × √17 = 6√34

x=\frac{-24\pm 6\sqrt{34}}{6}

Next, divide:

x=-4\pm \sqrt{34}

<u>The exact values of your x-intercepts are (-4 + √34, 0) and (-4 - √34, 0).</u>

Now to find the approximate values, solve this twice: once with the + symbol and once with the - symbol:

x=-4+ \sqrt{34},-4- \sqrt{34}\\x\approx 1.83, -9.83

<u>The approximate values of your x-intercepts (rounded to the hundredths) are (1.83,0) and (-9.83,0).</u>
