Answer:
87 days
Step-by-step explanation:
First if she already made 304 cranes and she makes 8 a day. Simply divide 304 by 8. You would then get 38. Next divide 1,000 by 8. You would get 125. You would subtract the total from how many days you need; 125, to how many days you already spent; 38. 125 - 38 = 87. 87 days are needed to make paper cranes.
Pickup a weighs about 1.,500 pounds pickup b weighs 685 kilogram’s which pickup actually weighs more
Answer:
pickup b
Step-by-step explanation:
Unit conversion :
1 kilogram is about 2.20462262 pounds
Solving :
⇒ Let's convert pickup b's mass into pounds
⇒ mass (pickup b) = 685 × 2.20462262
⇒ mass (pickup b) = 1510 pounds (approximately)
Clearly :
⇒ 1500 < 1510
⇒ mass (pickup a) < mass (pickup b)
Hence, pickup b weighs more.

there are 25 pounds of vegetables, how many pounds of protein are on the dinner plate?
Answer:
10 lbs
Step-by-step explanation:
25 is to 5 as x is to 2
25/5 = x/2
2 * 25/5 = x = 10 lbs

Find the probability of rolling factors of 24
Answer:
5/6
Step-by-step explanation:
The factors of 24 that are on a die are: 1,2,3,4 and 6. This only leaves 5 that isn't a factor of 24. Therefore, since there are 5 possibilities out of the 6 total numbers, the probability of rolling factors of 24 is 5/6.

x = 50.5°
Explanation:In order to solve, get to know about the sine rule:
[tex]\bf Sine \ Rule = \dfrac{A}{sinA} = \dfrac{B}{sinB}= \dfrac{C}{sinC}[/tex]
Solve for BD:[tex]\sf \dfrac{BD}{sin(50)} = \dfrac{5.6}{sin(78)}[/tex]
[tex]\sf BD = \dfrac{5.6(sin(50))}{sin(78)}[/tex]
[tex]\sf BD = 4.385686657 \ cm[/tex]
Then find angle D = 180° - 78° = 102°
Solve for angle C[tex]\sf \dfrac{4.385686657}{sinC} = \dfrac{9.3}{sin(102)}[/tex]
[tex]\sf C = sin^{-1}(\dfrac{4.385686657sin(102)}{9.3} )[/tex]
[tex]\sf C = 27.37 ^{\circ \:}[/tex]
Total Sum of interior angles of a triangle is 180°[tex]\sf B + C + D = 180^\circ[/tex]
[tex]\sf x + 27.37^\circ + 102^\circ = 180^\circ[/tex]
[tex]\sf x = 180^\circ - 102^\circ - 27.37^\circ[/tex]
[tex]\sf x = 50.53^\circ[/tex]
[tex]\sf x = 50.5^\circ \ \ \ (rounded \ to \ nearest \ 3 \ significant \ figure)[/tex]
Answer:
x = 50.5° (3 sf)
Step-by-step explanation:
Sine Rule for side lengths
[tex]\sf \dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]
(where A, B and C are the angles and a, b and c are the sides opposite the angles)
Find BD:
[tex]\implies \sf \dfrac{BD}{\sin BAD}=\dfrac{AB}{\sin BDA}[/tex]
[tex]\implies \sf \dfrac{BD}{\sin 50^{\circ}}=\dfrac{5.6}{\sin 78^{\circ}}[/tex]
[tex]\implies \sf BD=\dfrac{5.6\:sin 50^{\circ}}{\sin 78^{\circ}}[/tex]
[tex]\implies \sf BD=4.385686657...cm[/tex]
Angles on a straight line sum to 180°
⇒ ∠ADB + ∠BDC = 180°
⇒ 78° + ∠BDC = 180°
⇒ ∠BDC = 102°
Sine Rule for angles
[tex]\sf \dfrac{\sin A}{a}=\dfrac{\sin B}{b}=\dfrac{\sin C}{c}[/tex]
(where A, B and C are the angles and a, b and c are the sides opposite the angles)
Find ∠BCD:
[tex]\implies \sf \dfrac{\sin BCD}{BD}=\dfrac{\sin BDC}{BC}[/tex]
[tex]\implies \sf \dfrac{\sin BCD}{4.385...}=\dfrac{\sin 102^{\circ}}{9.3}[/tex]
[tex]\implies \sf BCD=\sin^{-1}\left(\dfrac{4.385...\sin 102^{\circ}}{9.3}\right)[/tex]
[tex]\implies \sf BCD=27.46935172...^{\circ}[/tex]
The interior angles of a triangle sum to 180°
⇒ ∠CBD + ∠BDC + ∠BCD = 180°
⇒ x + 102° + 27.469...° = 180°
⇒ x = 50.53064828...°
⇒ x = 50.5° (3 sf)

A recent study found that the average length of caterpillars was 2.8 centimeters with a
standard deviation of 0.7 centimeters. what is the probability that a randomly selected caterpillar will have a
length longer than (greater than) 4.0 centimeters?
Using the normal distribution, it is found that there is a 0.0436 = 4.36% probability that a randomly selected caterpillar will have a length longer than (greater than) 4.0 centimeters.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.In this problem, the mean and the standard deviation are given, respectively, by:
[tex]\mu = 2.8, \sigma = 0.7[/tex].
The probability that a randomly selected caterpillar will have a length longer than (greater than) 4.0 centimeters is one subtracted by the p-value of Z when X = 4, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{4 - 2.8}{0.7}[/tex]
Z = 1.71
Z = 1.71 has a p-value of 0.9564.
1 - 0.9564 = 0.0436.
0.0436 = 4.36% probability that a randomly selected caterpillar will have a length longer than (greater than) 4.0 centimeters.

What is the equation 8x-3y=6-4x in Stanford form?
Answer:
[tex]12x - 3y = 6[/tex]
Step-by-step explanation:
Standard form is written this way: [tex]Ax+By=C[/tex]
However, in this case, we just have to simplify 8x-3y=6-4x, as it is already mostly in standard form.
So, to do this, we have to combine like terms.
The only like terms that can be combined are -4x and 8x.
So, we add 4x to both sides, and we get: [tex]12x - 3y = 6[/tex].

A local baseball team is struggling this season, and many fans of the team believe it may be time to replace the head coach. To estimate support for firing the current head coach, a television news station provides a link on its website where fans of the team can respond to the question: "Do you feel the current head coach should be fired?” After 2,367 votes on the website, 79% of those who responded felt the coach should be fired. Which of these describes the type of bias in this survey and a likely direction of the bias in estimating overall support for firing the coach?
This is nonresponse bias. The result overestimates true support for firing the coach.
