lapo4ka [179]

Given that Johney's baseball had raised $1,456 out of $2,000 they need to play the tournament.

Amount of money they still need to raise is given by $2,000 - $1,456 = $544.

Given that there is a total of 11 players in the team. Let x represent the total amount each player needs to raise, then x = $544 / 11 = $49.45

Therefore, each player needs to raise $49.45

Answer:

Sample size shouldbe atleast 60

Step-by-step explanation:

Given that PTC is a substance that has a strong bitter taste for some people and is tasteless for others. The ability to taste PTC is inherited and depends on a single gene that codes for a taste receptor on the tongue. Interestingly, though the PTC molecule is not found in nature, the ability to taste it correlates strongly with the ability to taste other naturally occurring bitter substances, many of which are toxins.

Proportion of Italians who taste PTC =0.75

Margin of error <0.11

Confidence level = 95%

Std error of proportion = $\sqrt{\frac{0.75*0.25}{n} }$

Margin of error = $1.96*\sqrt{\frac{0.75*0.25}{n} }$ <0.11

$\sqrt{n} >1.96*\sqrt{0.75*0.25} /0.11\\=17.81*0.4330\\=7.71\\n>59.47\\$

Sample size shouldbe atleast 60

What is the answer what should I write down I will mark you the Brainlyiest 40 points so do it good!

Leni [432]

First you can count multiples of 7 all the way up to 84. 7,14,21,28,35,42,49,56,63,70,77,and 84.
Or you can do 7 x 12 equals 84.
Second write down the long division way 84/7.
7 goes into 8 one time write 7 at the top then write one at the bottom bring down the 4 and make it 14
you know 7 x 2 = 14 so 12 x 7 equals 14.
