Answer:
-2x² + 15
Step-by-step explanation:
Step 1: Add like terms
4x² - 6x² = -2x²
-10x + 10x = 0
3 + 12 = 15
Step 2: Rewrite
-2x² + 15
Answer:
946.242 milliliters
Step-by-step explanation:
The client drank 6 ounces of orange juice and 4 ounces of coffee for breakfast. We need to convert ounces to milliliters
1 ounce = 29.574 milliliters
6 ounces of orange juice
= 6 × 29.574 = 177.444 milliliters
4 ounces of coffee = 4 × 29.574 = 118.296 milliliters
For lunch, he consumed 8 ounces of tea and 6 ounces of ginger ale.
8 ounces of tea = 8 × 29.574 =236.529 milliliters
6 ounces of ginger ale = 6 × 29.574 =177.444 milliliters
4 ounces of water at 10:00 a.m. and at 2:00 p.m. this means 8 ounces of water.
8 ounces of water = 8 × 29.574 =236.529 milliliters
Total consumption by the client =
177.444 + 118.296 + 236.529 + 236.529= 946.242 milliliters
Volume of a sphere formula is: V=4
/3 πr^3
You know v=17000 and pi=3.14
17 000 = 4/3 x 3.14 x r^3
(divide 17 000 by 4/3 x 3.14 ) --> r^3 = 4060.51 (2dp)
(cube root is to get just r) r = 15.95 inches (2dp)
There 15 inches to the nearest inch.
Hope this is correct! :D
When we reject the null and the null is true, we have a made a type I error
The null hypothesis in statistics states that there is no difference between groups or no relationship between variables. It is one of two mutually exclusive hypotheses about a population in a hypothesis test.
null hypothesis is denoted as H₀
Reject the null hypothesis when the p-value is less than or equal to your significance level. Your sample data favor the alternative hypothesis, which suggests that the effect exists in the population. When you can reject the null hypothesis, your results are statistically significant.
when the p-value is greater than your significance level, you fail to reject the null hypothesis.
Sometimes , we reject our null hypothesis even when its true
there we made a type I error in hypothesis
