A ship maneuvers to within 2.50×103 m of anisland’s 1.76 × 103 m high mountain peak andfires a projectile at an enemy ship 6.18 × 102m on the other side of the peak, as illustrated. The ship shoots the projectile with an initialvelocity of 2.52×102 m/s at an angle of 73.4◦.The acceleration of gravity is 9.81 m/s2How close (vertically) does the projectilecome to the peak?

The annual snowfall in a town has a mean of 38 inches and a standard deviation of 10 inches. last year there were 63 inches of snow. find the number of standard deviations from the mean that is, rounded to two decimal places. 0.44 standard deviations below the mean 2.50 standard deviations below the mean 0.44 standard deviations above the mean 2.50 standard deviations above the mean

Consider a cube that has sides of length l. now consider putting the largest sphere you can inside this cube without any point on the sphere lying outside of the cube. the volume ratio -volume of the sphere/ volume of the cube is 1. 5.2 × 10−1 2. 3.8 × 10−1 3. 1.9 4. 2.5 × 10−1 5. 3.8

I’m really confused and need to learn this
