Guess how old I am. hints: I'm not really in college, I'm in Middle School. When you find out my age you are in for a shock for I, I am the youngest in my dock. less than 13, higher than 8 once you get it right, it's time to celebrate. P. S (The reason that the category is "Math" is because I am a Mathmagician So don't make this a compotion!)

The equation of a parabola is given. y=18x2+4x+20 what are the coordinates of the focus of the parabola?

According to a research study, parents with young children slept 6.4 hours each night last year, on average. a random sample of 18 parents with young children was surveyed and the mean amount of time per night each parent slept was 6.8. this data has a sample standard deviation of 0.9. (assume that the scores are normally distributed.) researchers conduct a one-mean hypothesis at the 5% significance level, to test if the mean amount of time parents with young children sleep per night is greater than the mean amount of time last year. the null and alternative hypotheses are h0: μ=6.4 and ha: μ> 6.4, which is a right-tailed test. the test statistic is determined to be t0=1.89 using the partial t-table below, determine the critical value(s). if there is only one critical value, leave the second answer box blank.

What is the slope-intercept form for each equation in this system? compare the slopes and y-intercepts to describe the graph of the system. 3x - 4y = 28 4x + 10y = 20
