Answer:

Its incorrect

Step-by-step explanation:

Area is width times height but in this case its 3 numbers so after you did width time height if I'm not mistaken you multiply that number by 4 so you were supposed to multiply 5 and 6 the answer is 30 and then multiply 30 by 4 which is 120 I think.

Kyle has a storage box that is 2 ft. Long, 3 ft. High, and has a volume of 12 ft. 3 12 ft.3. Myla has a storage box that is 4 ft

Alex17521 [72]

Answer: The widths of Kyle and Myla's boxes is the same as 2 ft.

Step-by-step explanation:

Formula : Volume of cuboidal box = length x width x height

$width=\dfrac{Volume}{length\times height}$

Given: Kyle has a storage box that is 2 ft. Long, 3 ft. High, and has a volume of 12 ft³ .

$width=\dfrac{12}{2\times3}=2\ ft.$

Myla has a storage box that is 4 ft. High, 2 ft. Long, and has a volume of 16 ft³.

$width=\dfrac{16}{4\times2}=2\ ft.$

Hence, the widths of Kyle and Myla's boxes is the same as 2 ft.

The number of potato chips in a bag is normally distributed with a mean of 74 and and a standard deviation of 4. Approximately w

aleksklad [387]

Answer:

99.8% is the percent of bags contain between 62 and 86 potato chips.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 74

Standard Deviation, σ = 4

We are given that the distribution of number of potato chips in a bag is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P( bags contain between 62 and 86 potato chips)

$P(62 \leq x \leq 86) = P(\displaystyle\frac{62 - 74}{4} \leq z \leq \displaystyle\frac{86-74}{4}) = P(-3 \leq z \leq 3)\\\\= P(z \leq 3) - P(z < -3)\\= 0.999 - 0.001 = 0.998 = 99.8\%$

$P(62 \leq x \leq 86) = 99.8\%$

Can someone help me out ? Don't just guess the answer :(

Monica [59]

1) 2m+6 / m² + 7m - 12 + (m+2)/(m+4)

= 2(m+3) / (m+4)(m+3) + (m+2)/(m+4)

= 2/(m+4) + (m+2)/(m+4)

= 2+m+2 / (m+4)

= m+4 / m+4

= 1 [ Option A ]

Answer 2) 3/ (x+4) + 7/ (x-3)

= 3(x-3) + 7(x+4)/ (x² +x - 12)

= 3x-9 + 7x + 28 / (x² +x - 12)

= 10x + 19 / (x² +x - 12) [ Option A ]

Hope this helps!
