PLEASE HELP ASAP Three friends entered a contest to count the number of jelly beans in a jar. The table shows their guesses of the number of jelly beans in the jar. There were actually 950 jelly beans in the jar.



Which statements are true?



Name Number guessed
Brandon 991
Li Mei 939
Jodi 976



Choose exactly two answers that are correct.

A. Li Mei’s estimate had about a 1.2% error.

B.Jodi had the highest percent error.

C. Jodi’s estimate had about a 26% error.

D. Brandon’s estimate had about a 4.3% error.

Answers

A. and D. For A multiply 950 by .012 and you get 11 (rounded) meaning she was off by about 11, which she was. You can instantly rule B out because Brandon was the furthest off not Jodi. For C multiply 950 by .26 and you get 247, she was not off by 247, she was off by 26, so that's wrong. And for D multiply 950 by .043 and you get 41 (rounded) which means he was off by 41, which he was. And there's your answer A and D are true :) Hope this helped

How does the simile in the line "The words leapt like a leaping sword" in Stanza 4 affect the poem? It creates a mental image of Columbus physically attacking his crew. It brings to life the energetic effect these words have on the sailors. It reminds readers that Columbus and his men are armed against natives. It calls attention to the fact that sailing to the New World was dangerous. Behind him lay the gray Azores, Behind the Gates of Hercules; Before him not the ghost of shores, Before him only shoreless seas. The good mate said: “Now must we pray, For lo! the very stars are gone. Brave Admiral, speak, what shall I say?” “Why, say, ‘Sail on! sail on! and on!’” “My men grow mutinous day by day; My men grow ghastly wan and weak.” The stout mate thought of home; a spray Of salt wave washed his swarthy cheek. “What shall I say, brave Admiral, say, If we sight naught but seas at dawn?” “Why, you shall say at break of day, ‘Sail on! sail on! sail on! and on!’” They sailed and sailed, as winds might blow, Until at last the blanched mate said: “Why, now not even God would know Should I and all my men fall dead. These very winds forget their way, For God from these dread seas is gone. Now speak, brave Admiral, speak and say”— He said: “Sail on! sail on! and on!” They sailed. They sailed. Then spake the mate: “This mad sea shows his teeth to-night. He curls his lip, he lies in wait, With lifted teeth, as if to bite! Brave Admiral, say but one good word: What shall we do when hope is gone?” The words leapt like a leaping sword: “Sail on! sail on! sail on! and on!” Then, pale and worn, he kept his deck, And peered through darkness. Ah, that night Of all dark nights! And then a speck— A light! A light! A light! A light! It grew, a starlit flag unfurled! It grew to be Time’s burst of dawn. He gained a world; he gave that world Its grandest lesson: “On! sail on!”
