Barry is trying to calculate the distance between point E(3, 1) and point F(4, 7). Which of the following expressions will he us
Alex777 [14]

Answer:

Option (1) is correct.

Barry uses the expression " square root of the quantity of 7 minus 1 all squared plus 4 minus 3 all squared " to find the distance between point E(3, 1) and point F(4, 7).

Step-by-step explanation:

Given : Barry is trying to calculate the distance between point E(3, 1) and point F(4, 7).

Distance between two points can be calculate using distance formula,

Distance formula states given two points P(a,b) and Q(c,d)  the distance between P and Q can be calculated using the given expression ,

D=\sqrt{(c-a)^2+(d-b)^2}

Thus,  distance between point E(3, 1) and point F(4, 7) can be calculate using above formula as ,

Here, a= 3 , b= 1 , c = 4 and d = 7

D=\sqrt{(c-a)^2+(d-b)^2}

Substitute above values, we get,

D=\sqrt{(4-3)^2+(7-1)^2}

D=\sqrt{(1)^2+(6)^2}

D=\sqrt{37}

Thus, Barry uses the expression " square root of the quantity of 7 minus 1 all squared plus 4 minus 3 all squared " to find the distance between point E(3, 1) and point F(4, 7).

Thus, Option (1) is correct.

Answer:

11%

Step-by-step explanation:

The full circle graph represents 100% of the given population. All populations are given except for "three or more." Adding all percentages of each population should add up to 100%.

No absences (none): 23%

One absence: 45%

Two absences: 21%

Three more absences: unknown.

Let the variable x represent the unknown population.

23% + 45% + 21% + x = 100%

Combine like terms.

89% + x = 100%

Subtract 89% from both sides.

x = 11%

To put it more simply, subtract all the percentages from 100% to get the percent of the missing population. 100 - 23 - 45 - 21 = 11
