Can anyone help with this??

  A

Step-by-step explanation:

Consider figure B. It has a uniform horizontal cross section of  2 m, and a height of 7 m. Its area is ...

  A = bh

  A = (2 m)(7 m) = 14 m²

__

Figure A decomposes into a rectangle that is 3 m × 5 m and an additional triangle that has a base of 3 m and a height of (7 -5) = 2 m.

The rectangle part of Figure A has an area of ...

  A = bh

  A = (3 m)(5 m) = 15 m²

Already this area is larger than the area of figure B, and we have not even added in the are of the triangle.

__

Figure A has the larger area.

Additional comment

The area of the triangle of figure A is ...

  A = 1/2bh = 1/2(3 m)(2 m) = 3 m²

so the total area of Figure A is (15 m² +3 m²) = 18 m².

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
