Answer:
none
Step-by-step explanation:
any value on y cancel 4y and then we will have -12=12 which is not true.
Step 1
Given; If Body temperatures of healthy adults have a bell-shaped distribution with a mean of 98.20°F and a standard deviation of 0.93°F.
Using the empirical rule, what is the approximate percentage of healthy adults with body temperatures between 96.34°F and 100.06°F?
Step 2
Answer: 6 cm
Step-by-step explanation:
Given: The ratio of the areas of two similar parallelograms is 4:9.
To find : The height of the bigger one if the smaller is of height 4 cm.
Let h be the height of the bigger one.
Since the areas of similar figures are proportional to the square of their corresponding sides.
Then, 
![\dfrac{16}{h^2}=\dfrac{4}{9}\\\\\Rightarrow\ h^2=\dfrac{9}{4}\times16\\\\\Rightarrow\ h^2=36\\\\\Rightarow\ h= 6\ cm\ \ \ \ \text{[ height cannot be negative.]}](https://tex.z-dn.net/?f=%5Cdfrac%7B16%7D%7Bh%5E2%7D%3D%5Cdfrac%7B4%7D%7B9%7D%5C%5C%5C%5C%5CRightarrow%5C%20h%5E2%3D%5Cdfrac%7B9%7D%7B4%7D%5Ctimes16%5C%5C%5C%5C%5CRightarrow%5C%20h%5E2%3D36%5C%5C%5C%5C%5CRightarow%5C%20h%3D%206%5C%20cm%5C%20%5C%20%5C%20%5C%20%5Ctext%7B%5B%20height%20cannot%20be%20negative.%5D%7D)
Hence, the height of bigger parallelogram = 6 cm
Answer:
y = 2x - 9.
Step-by-step explanation:
2y - 4x = -18
Add 4x to both sides:
2y = 4x - 18
Divide both sides by 2:
y = 2x - 9.
